In the present study, the most useful stainless steels of in nuclear industry, i.e. 304, 304L and 316L were provided and laser cut into 0.5*0.5 cm dimension. The effect of radiation on physical properties of samples were investigated. Gamma irradiation on samples was done with a 60Co radioisotope to the doses of 100 and 200 kGy. The resistance of the samples was measured through the Four-Probe ...
