دراسة تاثير اسعة كاما على الخواص الكهربائية لبعض الموارد المعدنية

We calculate the electrical resistively (ρ) and conductivity (σ) for some pure (Pb, Fe, Ni, Zn, Al, Zn) by calculate resistance (R) before and after these samples were exposed to y-rays at room temperature for two days. We notice there decrease in values of increase in values of for all samples, also radiation didn't effect the nature of these cures in general.
