Owing radiobiological epidemiological knowledge, the UNSCEAR and 'International Commission on Radiological Protection'-ICRP have established stochastic radiation induced dose-effect relationships methods (Masood et al., 2013; Lochard, 2003). [...]we adopted the procedure described by ICRP (Publication 60) (Masood et al., 2013; ICRP, 1990) and complied by UNSCEAR for the assessment of lifetime risk of fatal and nonfatal cancers from exposed personnel from the departments: According to ICRP (Publication 60) (1990), the 'nominal 'probability coefficient' for stochastic effects (for adult workers for medical field) is fatal cancer is 4.0x10-2 (detriment per Sievert) and for non-fatal cancer is 0.8x10-2 (detriment per Sievert). According to the UNSCEAR (2000) Report data, with the average medical radiation exposure (0.33 mSv/a) the lifetime risk estimated is mentioned as 4.6x10-4 for fatal cancer related to 35 years of occupational exposure to IR (Masood et al., 2013). In current study, all measured lifetime fatal and lifetime non fatal cancer risks values were lesser than the previously risk values for all radiation workers of INMOL (Table 1). [...]all risk values in INMOL's occupational radiation workers were lesser than the other carcinogens' (Nickel, Arsenic, Benzene, and Asbestos) lifetime occupational cancer risks.
