Previously, numerous studies have focused on radi- ation-induced genetic effects using animal models9). Radiation has been proved to be carcinogenic in all types of experimental animals (mice, rats and monkeys for X-radiation and mice, rats, rabbits and dogs for gamma radiation) and has been shown to induce tumors in at least 17 different tissue sites, that is, sites at which tumors have been observed in humans (i.e., leukemia, thyroid gland, breast and lung)10).
Radiation technicians are qualified and authorized personnel performing different radiation- related examinations in hospitals and private clinics. They are occupationally exposed to radiation emitted from X-ray devices for a long time during handling of patients for diagnostic and therapeutic purposes11). However, the level of exposure depends on the work- ing area, exposure time, job rotation and protective measures adopted by the individual workers12). Trends in radiation exposure for both patients and staff are affected not only by advances in radiation protection but also by the level of doses used in the practice of medicine13).
