## A B S T R A C T To assess the safety of disposal of radioactive waste material in concrete, curing conditions and time of leaching radionuclides 60Co and 137Cs have been studied. Leaching tests in concrete were carried out in accordance with a method recommended by IAEA.(1)
Female albino rats of a Wistar strain were exposed to either 135 r or 270 r of Co"-radiation on the morning of day 11 (Witschi stage 17). Autopsy on day 20 revealed that the lower dose produced a slight increase in the degree of resorption, no effect on fetal weight and no malformations in the survi
