Doses of enriched uranium in testes inducing dominant lethality and skeletal abnormalities in offsprings are estimated.When intratesticular injection dose is 0.4～60μgenriched uranium;from intake to insemination, testes could receive 9.14×10-5～1.38 ×10-2 Gyradiation dose.Experimental results show that with the increase in the absorption dose, the number of living fetuses in a litter decreases,dominant lethality and skeletal abnormalities rise.It should be noted that relatiollship between the injected dose(I in μg) and the incidence of dominant skeletal abnormalities (S in %)in the offsprings can be represented by equation:S=28.84+0.84I.
