It was shown using micronucleus test that Cd chloride in drinking water (5 mg Cd2+/1, 32 days) does not induce cytogenetic damages in mouse bone marrow cells and does not affect the yield of micronuclei (MN) after chronic gamma-irradiation (1 Gy), whereas Cd chloride injection (1 mg Cd2+/kg body wt) leads to an increase in the number of MN. At the same time, both acute and chronic Cd2+ treatment decrease the number of MN induced by acute irradiation. The protective effect of Cd2+ is supposed to be due to activation of repair processes or metallothionein induction.
