[Mutagenic properties of irradiated fresh fish in a chronic experiment].

The mutagenic action of fresh fish irradiated in a dose of 200 kGy was studied in chronic experiments on 5 generations of rats. The mutagenic activity was assessed from the induction of dominant lethal mutations in sex cells of males and from the formation of chromosome aberrations (bridges and fragments) in bone marrow. The results of calculating the mutagenicity rate and cytogenetic analysis indicated no mutagenic action of irradiated fresh fish on sex cells and bone marrow of rats given irradiated fish for a long period of time.
