Determination of irradiation dose and distinguishing between irradiated and non irradiated fish meat by real-time PCR.In this study, the effects of gamma irradiation on the DNA of fish (Oncorhynchus mykiss) by real-time PCR were studied. 
real-time PCR
Fish (O. mykiss) were exposed to radiation doses of 0.250, 0.500, 1, 3, 5, 7, and 9 kGy in a gamma cell.
