The fitted equations to describe the retentions of α radiator ²³⁵U and β¹⁴⁷Pm as well as γ¹³⁴Cs were obtained respectively. The half life component of ²³⁵U is the longest, T_1/2=197d; of ¹⁴⁷Pm is shorter, T_1/2=76 d; and of ¹³⁴Cs is the shortest, T_1/2=5.1 d. For the rates of sperm abnormality induced by 1 cGy cumulative absorption dose the ratio of reproductive toxicity is α:β:γ =28:3:1. For the frequencies of chromosome aberrations in spermatogonia induced by 1 cGy cumulative absorption dose, the ratio of reproductive toxicity is α:β:γ=29:4:1. In the general, reproductive toxicity of α radiator ²³⁵U is the biggest, next β¹⁴⁷Pm, finally γ¹³⁴Cs.
