deep dose calculated in the production of 18F radioisotope in water target collision with plasma focus device

One of the reasons for the use of PET radioisotopes in medical research is the presence of a series of positron emitters such as 11C, 13N, 15O, and 18F. The detectors combined with them perform a series of processes similar to natural processes in the body. Another advantage of this method is imaging of metabolic function, which causes early detection of dangerous diseases such as cancerous tumors, cardiovascular diseases, neurological diseases such as epilepsy, Parkinson's disease, and allows the doctor to treat the disease before it develops. In this research, in search of radioisotope production devices with short half-lives, to simulate the depth dose received by a phantom cube of water geometries are 20 cm at a distance of 50 cm from the spring and firing one million photons from a point spring with the energy of 25 MeV Cylindrical water with a radius of 7 cm and a height of 3 mm in order to produce radioisotope F18, Geant tool 4.10.7 has been used and to have safe radiotherapy, the received deep dose has been calculated with appropriate results.
