The examination of dental images is a crucial method for diagnosing diseases, devising treatment plans, and assessing treatment progress by dentists. While X-rays are beneficial in treating certain ailments, they also pose risks; thus, safeguarding against X-ray exposure is paramount for both dentists and patients. A study was undertaken to evaluate the awareness, attitudes, and practices of dentists in Birjand concerning ionizing radiation effects and protective measures.

This descriptive-analytical research, employing random sampling, assessed dentists' knowledge, attitudes, and practices through questionnaire distribution. Data were gathered from 111 dentists in Birjand and analyzed using t-tests and analysis of variance with SPSS 20 software.

The study comprised 52 males (46.8%) and 59 females (53.1%). Average scores for dentists' knowledge, attitude, and practices in radiation protection were 77.85%, 83.5%, and 43.7%, respectively. Notably, no statistically significant disparity was observed in knowledge levels between those who had completed retraining courses and those who had not (P>0.05). Furthermore, 35.1% of participants utilized lead aprons, while 73.8% employed thyroid necklaces for patient protection.

Findings indicated that dentists in Birjand exhibit a satisfactory level of knowledge and attitude towards radiation protection. Despite the lack of a significant difference in awareness between retraining course attendees and non-attendees, there was a collective interest in participating in such courses. Hence, it is recommended that refresher courses incorporate updated radiation protection guidelines.

Radiographers’ awareness about the principles of radiation protection and the physical principles of digital radiology devices can play an important role in obtaining quality images and reducing the dose of patients. The purpose of this study is to evaluate the level of students and radiologists awareness of Khorasan province in the field of radiation protection principles and physical principles of digital imaging systems.

Methods and Materials:

 A digital radiography questionnaire was used in this study whose validity and reliability were confirmed. The first part of the questionnaire included demographic questions. The second part included 11 questions about the principles of radiation protection and 11 questions about the physical basics of working with digital radiography devices. If the answer is correct, a positive score is given and other options are given a zero score. The third part, which was specific to radiographers, included a question about participating in previous training workshops.

The level of awareness about the principles of radiation protection in radiographers (score 49.08 ± 14.45) was significantly higher than that of students (score 66.63 ± 16.99) (P < 0.05). The level of awareness about physical basics in students (score 54.27 ± 17.09) was significantly higher than radiographers (score 39.36 ± 10.45) (P < 0.05). The level of awareness about physical principles had a significant and negative relationship with age and work experience (P < 0.05).

Radiographer’s level of awareness about the physical basics of digital imaging systems is insufficient. It is necessary to increase radiographer’s level of awareness in this field through the development of continuous training programs.

Risks and complications caused by long-term exposure to ionizing radiation can reduce job satisfaction in radiologists. Improving the level of knowledge, attitude and performance can be effective in increasing their job satisfaction.  The present study was conducted with the aim of determining the job satisfaction of radiographers and its relationship with knowledge, attitude and performance towards the principles of radiation protection among radiographers in Sanandaj, 2018.

The present study was an analytical cross-sectional study that was conducted on 63 radiologists working in the radiology departments of Sanandaj city. Sampling was done by census. The data was collected by using a demographic characteristics questionnaire, a job satisfaction questionnaire, and a questionnaire to measure the knowledge, attitude and performance of radiographers about the principles of radiation protection in radiographers. Data analysis was done using SPSS-16 software at a significance level of 0.05.

The mean and standard deviation of the job satisfaction score was 82.90±12.50. There was no significant relationship between job satisfaction score with knowledge, attitude and practice. There was a statistically significant relationship between the average practice score and marital status(P=0.02), education(P=0.002) and employment status (P=0.009).

Despite the fact that the job satisfaction of radiation workers is desirable, it is necessary to take steps to maintain and improve the job satisfaction of radiation workers by paying more attention and facilitating the environmental and organizational factors of the workplace. It seems that in order to investigate the relationship between job satisfaction and knowledge, attitude and performance parameters, more research with a larger sample size is needed.

Using computed tomography (CT) scan may cause complications in the eye lens, thyroid gland, and breasts. One of the radiation protection methods to protect patients from unnecessary and unintended exposures is utilizing non-lead shields in CT-scan tests. Before designing and using these shields, it is necessary to study their performance by a simulation.

Bismuth, tungsten, and tin with absorption edges in diagnostic radiology energy ranges were selected for this research. Each of the metals along with the silicon was used as building blocks in the Monte Carlo simulation. To determine the mass attenuation coefficient of the samples, the beam was simulated as single energy. The energy range was selected according to the common imaging tests in diagnostic laboratories from 20 to 140 keV with 20 keV steps. The flat photon source with a radius of 5 mm was placed at the origin of the geometry. Information obtained from the simulation could specify that the shield had the most attenuation coefficient at which energies.

The shield containing 10% bismuth and 90% silicon showed more attenuation in the energies above 100 keV. Tungsten and tin shields also showed greater attenuation at medium and low energies.

By using the effect of attenuation window and selecting proper percentage and metal for the energy applied in diagnostic radiology, patients can be protected from radiation exposure to radiosensitive superficial organs.

Radiology technicians have a critical role in protecting patients along with providinghigh-quality images. The present study assessed radiology students' last semester about the principlesof protection, dose level, and cancer risk of ionizing radiation applied for diagnostic imaging. This studywas conducted in training hospitals of Ahvaz Jundishapur University of Medical Sciences, Ahvaz City, Iran.

 This cross-sectional descriptive study was performed using a study-designed questionnaire.The sample size was 40, and statistical analysis was performed in SPSS v. 24.

 Only 15% of students correctly answered the question of ionizing radiation stochastic effect. While70% of students stated the average dose of an abdominal ultrasound correctly, only 2.5% of them determinedthe average dose of a myocardial nuclear medicine scan correctly. In total, the respondents received 35% ofthe overall score of knowledge about cancer risk caused by ionizing radiation of imaging examinations.

 The students' knowledge about the principles of radiation protection was moderate, andtheir knowledge about the level of radiation dose and cancer risk caused by various imaging procedureswas insufficient. Theoretical and practical education has a significant role in improving the knowledgeand skills of radiology technicians. So, repeating and emphasizing the principles of radiation protectionand paying more attention to these topics in the courses and internships of radiology technology studentsseems necessary. These measures will improve the performance of students and make them preparedto accept their future professional responsibilities.

Today, the use of dental radiography equipment in dental centers has increased due to its high application in the diagnosis of dental diseases. As a result, concerns are increasing regarding repeated exposure to this low dose level of radiation. Therefore, the knowledge and practice of dentists about radiation protection are essential for themselves and the patients. This study aimed to assess the knowledge and practice of dentists about radiation protection.

This cross-sectional study was performed based on a questionnaire in several cities of Iran. The first part of the questionnaire included such information as gender, years of work experience, and participation in radiation protection workshops. The second, third, and fourth sections consisted of questions on radiobiology, radiation protection, and performance, respectively.

In this study, 94 dentists participated, and the mean scores of dentists (out of 5 points) for radiobiology knowledge, radiation protection knowledge, and performance were obtained at 2.66±1.1, 2.80±1.01, and 2.87±1.37, respectively. The results of Pearson analysis showed that general knowledge had a significant relationship with performance (P=0.014). There was also a significant relationship between the history of participation in radiation protection workshops and performance (P=0.01).

It was found that more knowledge about the effects of ionizing radiation on the body and more awareness of the principles of radiation protection would help dentists to better observe the practical principles of radiation protection. Also, participating in radiation protection workshops could increase dentists' knowledge, and therefore, improve their performance.

The staff of angiography departments is exposed to ionizing radiation for a long time every day. Due to the destructive effects of these radiations on people and their next generations, the knowledge of the radiation protection principles has an important role in reducing the biological effects of radiation. In this study, the radiation staff's knowledge about the radiation protection standards in angiography departments of Mashhad educational hospitals is investigated.

A researcher-made questionnaire, including demographic information and technical questions about the knowledge of radiation protection principles, rules, and also observation of this principles, were completed by the angiography departments' radiation staff of educational hospitals of Mashhad.

The mean score of the radiation staff's knowledge was estimated as %52.31±%12.21. The results showed a significant positive and moderate correlation between the score of knowledge and person's work experience. The knowledge score of staff with "the minimum exposure time to the radiation" was more than the other group that did not follow the minimum exposure time to the radiation.

The results of this study showed the knowledge of angiography department staff was relatively low, which was especially evident in people with less work experience. Considering that all participants in this study declared that the holding of training workshops related to this subject is necessary, therefore, purposeful planning should be performed to hold retraining classes continuously.

Most exposure of people to artificial sources through diagnostic radiographs is due to the increase of these tests in the community and the inevitability of these tests. Optimizing the dose of skin inlet can play an important role in reducing radiation exposure, which can be achieved by monitoring the inlet dose as a key parameter.The purpose of this study was to evaluate the rate of skin input dose in routine radiographic tests at Loghman Hakim Hospital in Tehran to compare the doses recommended by the International Commission for Protection against Radiation (ICRP) as well as, if possible, to provide simple guidelines for dose reduction and optimization. Patients with preserved image quality.

This descriptive study was performed in Loghman Hakim public hospital in Tehran with 235 patients 100 females and 135 males with a weight range of ± 10 kg. In this study, skin doses of patients were measured using four diagnostic radiographs of IAEA standards, in 12 common radiographic views using thermoluminescence chips and Geiger Müller dosimeter.

The doses of skin for each radiographic method in milligrays were as follows: Chest (posterior-anterior) 0.34, Chest (1.85), Abdominal (anterior-posterior) 3.31 , Hip (anterior-posterior) 4.79, cervical (anterior-posterior) 1.95, cervical vertebra (1.24), dorsal (anterior-posterior) 2.38, dorsal vertebrae (profile) 4.68), lumbar vertebrae 3.95, lumbar vertebrae 9.53, skull (antero-posterior) 29.2 and skull 1.89.

This study shows that the rate of skin inlet dose in the twelve investigated facets was in accordance with the recommended doses and was in line with the standards provided by the International Commission for Protection against ICRP and also optimized the radiation parameters. And standardizing radiographic conditions by preserving the image quality will reduce the dose received by patients. In this regard, dosimetry at regular intervals and periodic and regular quality control tests of radiographic devices can be optimized, monitored, reduced dose. And protecting patients as well as assessing potential harm The object of radiation will be effective.

 Ionizing and non-ionizing radiation are widely used in the diagnosis and treatment of diseases. Considering the potential risks of radiation, radiation safety training courses are important for medical staff.

 The aim of this study was to investigate the effectiveness of one-day radiation safety training program in increasing the radiation safety knowledge of physicians.

 In this descriptive-analytical study, subjects were 12 physicians (6 general practitioners and 6 non-radiologist specialists) participated in the training program organized by Qazvin University of Medical Sciences in 2018. A researcher-made questionnaire was used for surveying physicians before and after the training. The mean and standard deviation of the scores were first calculated. Then, the pre- and post-test scores were compared using Wilcoxon signed-rank test, and the correlation of these scores with their age, gender, expertise area, and work experience was examined by Spearmanchr('39')s correlation test.

 The mean total scores of the physicians before and after training were 7.00±2.56 (ranged 3-11) and 11.92± 2.31 (ranged 8-15) out of 18, respectively. The radiation safety knowledge of physicians significantly increased after training (P<0.001). No significant relationship was found between their scores and their age, gender, expertise area and work experience.

 The radiation safety training program was effective in increasing the radiation safety knowledge of physicians and it can be used for a larger community of physicians.

Radiation protection of patients, personnel and other people is very important in medical imaging using ionizing radiation (such as X-rays and gamma rays). These radiations can cause various biological damages such as carcinogenesis, cataracts, embryonic injuries. Therefore, the knowledge of radiation protection of radiation workers is very important and the purpose of this research is to assess the radiation protection knowledge of radiology technologists in military hospitals in Tehran. This research is descriptive-analytic and cross-sectional study. A questionnaire about the knowledge, attitude, and performance of radiation protection was distributed among the 80 radiation technologists of Tehran’s military hospitals. The data of the completed questionnaires were analyzed using one-way ANOVA, sample t-test and Spearman/Pierson correlation tests in SPSS-19 software. The mean of the obtained radiation protection knowledge score was 11.20 ± 4.28 out of 20. There was no significant difference between the radiation protection knowledge, performance knowledge and motivation among graduates of AJA and other universities as well as between men and women. There was a very weak correlation between age with knowledge of radiation protection and performance as well as between education with knowledge of radiation protection, performance knowledge and motivation. Comparison of our investigation results with previous studies showed that the level of radiation protection knowledge of Army Radiology technologists is low. It was also determined that age, gender, and work experience had no effect on the functional knowledge and radiation protection knowledge, nor did it have an impact on knowledge, performance and motivation with increasing educational level.

Cerium oxide nanoparticles, or nanoceria, as radioprotectors can play an important role in reducing complication of ionizing radiation. The aim of this study was to reduce the mortality of normal lung cells against 6-MV photon beams by using nanoceria; so that through identifying optimal concentration of nanoceria, it could be used in radiation therapy.
Nanoceria suspensions were sterilized with 70% ethyl alcohol. In order to optimize the nanoparticles distribution in aqueous medium, suspension was shaken by vortex for 3 minutes. Then, the sonication was performed for 2 hours using ultrasound sonicator. MRC-5 cells were cultured in Dulbecco's modified eagle medium/F12 (DMEM/F12) medium, and placed in a high-humidity incubator at 37 °C. To determine the non-toxic concentration, the cells were treated with serial concentrations of 5, 10, 30, 50, 70, 90, 110, 150, 200, 250, and 300 µM of nanoceria. Quantitative radio-protection effect of nanoceria was performed in non-toxic concentrations against 6-MV X-ray with doses of 20, 40, 60, 80, and 100 cGy.
Findings: The concentration of 70 μM and low concentrations did not have toxicity for MRC-5 cells. The mean cell viability (%) in this concentration of nanoceria was 89.4 ± 2.6 percent. MRC-5 cells at presence of 70 µM anoceria had significant radiation protection against radiation doses of 40, 80, and 100 cGy compared to the control group.
Using cerium oxide nanoparticles can increase the precision of treatment, and reduce secondary effects of radiotherapy.

Inequalities of geographical areas due to inappropriate concentration of facilities in various socio-economic areas have led to an increase in potential health risks for people in the community. Radiation protection in hospitals is a very important topic due to some economical, health, human and moral considerations. In order to promote a radiological protection program in hospitals, it is very important to have a good knowledge and attitude, as well as proper practice of personnel in this area. Therefore, the purpose of this study was to investigate the current status regarding knowledge, attitude and practice of operating room personnel about radiation protection in Iran.
This descriptive cross-sectional study was performed on 332 operating room personnel with random selection in hospitals on the knowledge, attitude and practice at different cities in Iran. To do so, the operating room staff was considered as a statistical society in 1394-95. The respondents to the questionnaire included physicists, nurses, apprentice and secretaries in different hospitals with low, medium and large number of beds. The selected provinces included: Alborz, East Azarbaijan, Tehran, Khorasan Razavi, Semnan, Qom, Golestan, Gilan, Kurdistan, Kermanshah and Mazandaran.
The findings of this study indicate that there is a significant relationship between the level of knowledge, attitude and practice of operating room personnel in radiation protection and different provinces. Also, the number of hospital beds is affected by the level of knowledge, attitude and performance of the personnel.
According to the findings, it can be concluded that the existence of differences can be due to the lack of care and facilities and the lack of experience of personnel, the number of specialized and limited specialized staff in conducting in-service training courses that necessitates the importance of taking strategies to eliminate them.

In mammography absorbed dose is insignificant. Biologically, in normal people, the phenomenon of hypersensitivity to low doses occurs. The purpose of this study was to investigate the synergistic of Single-Walled Carbon Nanotube (SWCNT) in the polymer substrate of Poly Dimethyl Siloxane (PDMS) in common energy in mammography.
Cerium oxide nanoparticles and SWCNT were added into the PDMS polymer in order to fabricate 15 layers of nanocomposites. The dispersion of nanoparticles in the polymer was investigated by Field Emission Scanning Electron Microscopy (FE-SEM). At mammography unit of Motahari Hospital, the nanocomposites were irradiated with 28 kV tube potential. The radiation characteristics were then recorded by the piranha dosimeter. The results of radiation attenuation were calculated. Statistical analysis with Kruskal-Wallis test was performed with a significance level of less than 0.05.
The results of the FE-SEM showed the excellent dispersion of nanoparticles. It indicated the accuracy of the range (10-30 nm) of particle diameter. The characteristic of the beam quality (0.338 mm Al) was correctly within the defined range. The statistical analysis resulted in a P-value of 0.027, which it indicated a significant difference in the amount attenuation of nanocomposites. By adding SWCNT into samples, the absorption was increased by up to 3%. The most important achievement was a 12% reduction in weight, for hybrid nanocomposites (25% cerium oxide nanoparticles SWCNT) than those that contained only 25% of the cerium oxide.
The results showed that cerium oxide, based on PDMS, is able to attenuate X-rays. In addition, single-wall carbon nanotubes can be effective in improving the effectiveness of protective clothing in terms of increasing attenuation and decreasing weight in mammography.

In the vicinity of some of radiation therapy centers, measured exposure may not agree with calculated values due to the skyshine phenomenon. The aim of this study was to determine a computational model to predict the dose of radiation skyshine via Monte Carlo simulations.
The simulation of linear accelerator head, skyshine geometry, and skyshine dose calculation at several heights and for different roof thicknesses was done using Monte Carlo N-Particle eXtended (MCNPX) code. The simulation results were validated via measuring and then were compared with the Council on Radiation Protection-151 (NCRP151) model results.
Findings: The results of dose distribution in skyshine simulated model for all thicknesses of roof and every height from ground level showed an increase in the dose up to about 10 meters distance from the isocenter and then a decrease by distance from the isocenter; while the dose in the NCRP151 model, continuously decreases by distance. In addition, the amount of dose in each point was around 50 times larger than the simulated values. Dose reduction in both methods was proportional to the inverse-square.
The model developed in this study can be used to predict the skyshine dose when designing a radiotherapy facility. The developed model is superior to the NCRP151 model due to its ability to calculate the dose in every point, inside and outside of treatment room, to investigate the influence parameters such as ceiling thickness and height from ground level and to determine the point with maximum dose.

Anode heel effect refers to reduction of radiation intensity in the anode side of X-ray tube. This variation in radiation intensity across the anode-cathode of X-ray tube can be benefited for decrease radiation exposure in some radiological examinations. The aim of this study was to evaluate the effect of anode heel orientation on the radiation dose received by the testes in male patients undergoing pelvic radiography.
This is a cross-sectional study, conducted at one of the teaching hospitals of Ahvaz, Jundishapur University of Medical Science Ahvaz, Iran, from September 2015 to March 2016. In order to measure the profile of radiation intensity variation, 13 paired sets of high radiosensitive cylindrical lithium fluoride thermo-luminescent dosimeters (TLD) aligned on the cathode-anode central axis upon the table and then irradiated using routine exposure parameters. The anode of X-ray tube was positioned toward the feet for 40 patients and toward the head for 39 patients undergoing pelvic radiography. For measure the entrance skin dose (ESD), 8 TLD chips were located on the central point of the radiation field and 5 TLDs were located on the testes position to measure the dose received.
Radiation intensity profile showed that radiation intensity decrease from the cathode to the anode side. Discrepancy of radiation intensity on central axis of cathode-anode was calculated about 35%. The radiation dose received by the testes was 26.74% lower for patients the anode directed toward the feet, compared to the patients in which the anode directed toward the head (FTC: 1.260±0.296 mGy, FTA: 0.923±0.167 mGy, P In pelvic radiography, positioning of testes directed to the anode of X-ray tube can decrease the receive dose.

Ionizing radiations are one of the harmful factors in workplaces, so this study aimed to determine the radiation protection condition in radiology centers in educational hospitals of Ahwaz University of medical sciences.
Methods and Materials: This research was a cross-sectional study that was performed among 25 active radiology rooms in 2013. First, an expert visits the radiology centers. Second, dosimetery was performed with Gaiger-Moler–DGM-1500 dosimeter. Finally the related standard checklist was completed. The checklist included general constructions and protective equipment’s conditions. In addition, the status of ray room, darkroom, and control room were monitored. Data were analyzed using SPSS version 19.
96% of these centers had an appropriate ray room and dark room. 64% of them had favorable store. From The viewpoint of environmental health parameters, all centers had desirable sewage collection and water piping. Only 68% of centers performed quality control of their equipment and 94% of them had several protective equipment for patients. Staffs protection against radiation was desirable in all of the centers.
Discussion and Due to the lack of adequate and accurate expert monitoring, quality control of equipment and patient’s protection was not appropriate.

More than 80% of patients need to take x-rays during their diagnosis and treatment stages. Due to the biological effects of ionizing radiation, observance of radiation protection principles are necessary. The observance of radiation protection principles in intensive care units at Imam Reza hospital of Kermanshah in 2014 was evaluated in this study.
In this cross-sectional study which was performed by census method, performance of 38 radiographers working in target center was investigated regarding the following of the principles of radiation protection in respect of patients, nurses, radiographers, and other clients in intensive care units. Data collection tool included a questionnaire and a checklist of 31 principles of radiation protection.
The overall level of observance of radiation protection principles in intensive care units was at an appropriate level (94.7%) in 36 radiographies. The highest and lowest levels of principle observance of radiographers were in respect to themselves (94.7%) and nurses in the intensive care units and other clients (26.3%), respectively.
According to results in this study, radiation protection principles observance by radiographers during portable radiography examinations respect of themselves is appropriate but respect of other nurses is not satisfactory. It seems that it can be improved to 100% of the optimum level by equipping intensive care units to protective equipment, setting some obligations to use them, and controlling and continuous monitoring of protective measures of radiographers.

Introduction and The growing use of ionizing radiation in disease diagnosis necessitaes the appropriate use of devices and awareness regarding the principles of radiation protection. With appropriate adoption of personal protection equipment and compliance with the existing regulations in relation to protection of the buildings where sources of ionizing radiation are located in, the adverse effects of radiation can be curtailed to a great extent.
In this descriptive, analytical, cross-sectional study, we investigated the rate of compliance with radiation protection standards of 45 radiography rooms in 32 diagnostic imaging centers in Khuzestan Province, Iran, 2015. The centers were chosen through random cluster sampling method. The data were obtained using open-ended interview and a checklist designed based on the recommendations of the International Commission for Radiation Protection and Atomic Energy Organization of Iran.
The compliance rates with regard to radiology room, radiology equipment, darkroom, and radiographer’s protection were 80.76%, 80.47%, 69.28%, and 93.12%, respectively. Maximum and minimum rates of compliance with the standards were related to performance of the cassette tray (100%) and hopper status (25%), respectively. Comparison of public and private imaging centers in terms of safety standards showed no significant differences (P>0.05).
The observance of the radiation protection standards in Khuzestan Province was in a relativly desirable condition. However, there are some shortcomings in compliance with the principles of protection in the darkroom. In this regard, with recommend adopting protection measures such as timelyreplacement of processing solution, appropriate ventilation of darkroom, provisionof protection equipment and appliances, and protection training required for entering the darkroom.

Cardiac CT (Computed Tomography) angiography applies as a pre-exam method for evaluating the patients with medical problems in their cardiac arteries. Due to the high delivered dose in this imaging method, dose reduction techniques and imaging strategies that serve the images quality with minimum patient dose are the subjects for investigation and research studies. This study will evaluate and discuss the clinical aspects and dose reduction techniques in cardiac CT angiography briefly.
Methods and Materials: This research is theoretical and analytical method that was performed by searching “cardiac CT angiography, radiation protection, and patient’s dose reduction methods” key words in the Google Scholar, Science Direct, PubMed and Scopus web sites in terms of content (Content Analysis). This article was written based on the 10 chosen articles which were found after the research in the internet web sites.
Various applied techniques like tube current control using ECG (electrocardiogram), X-ray tube voltage reduction, scan sequence changing methods, greater detector coverage and working modes with higher pitches are available in cardiac CT angiography for reduction in the delivered dose to the patients.
Discussion and Several applied strategies are available for dose reduction in cardiac CT angiography in daily applications. Most of these dose reduction strategie which are useful in many patients can be used in most of the clinical cases. Nowadays, many of techniques using dose saving algorithms were presented commercially. It is very essential and important to adapt the scan protocol with any possible dose reduction strategy for every patient as mentioned in the American heart institute scientific meeting in 2008. Combination of several dose saving algorithms are usually feasible and cause to more effective dose reduction in cardiac CT angiography.
