Abstract

Study of antenatal and postnatal development of two generations of posterity of male Wistar rats which spermatides were gama-irradiated (⁶⁰Co) with doses below those causing sexual sterility (0.5-1.5 Gy, dose rate 0.003 Gy/s) is presented. The greatest changes are found at embryonic growth of posterity of both generations. This means that gama-radiation causes genomic instability.

Key words
Wistar rats, males, irradiation of spermatides, posterity.
