A study to analyze local dose reference level values in Kohgiluyeh and Boyer-Ahmad as a deprived area

Local Dose Reference Level (LDRL) values as the standard radiation dose of all radiography examinations are used in medical imaging to reveal the patient dose level or administered activity for a specified imaging procedure.

The incident air kerma (Ki) was measured for five radiographic examinations (Skull AP/Lat, Chest AP/Lat, Lumbar AP/Lat, Thoracic AP/Lat and Pelvic AP) throughout the province of Kohgiluyeh and Boyer-ahmad (as a deprived area). The founding DRLs results were sort; the third quartile was selected as the average DRL and compared with the other DRLs provinces of Iran as well as the standard data of developed countries.

The radiographic LDRL were found to be 0.72, 1.62, 3.06, 2.96, 7.21, 9.99, 7.1, 8.42 and 5.56 mGy for Chest PA, Chest Lat, Skull AP, Skull Lat, Lumbar AP, Lumbar Lat, Thoracic AP, Thoracic Lat and Pelvic AP, respectively.

The founding revealed that if the applied radiation protocols are as same as developed countries the DRL values in some projections such as the lumbar vertebrae could be close to international references.
