[The genetic monitoring of the house mouse population from areas contaminated by radionuclides as a result of the accident at the Chernobyl Atomic Electric Power Station].

In 1986-1994, genetic effects of radiation on males of wild mice caught in areas of radioactive contamination after the Chernobyl reactor accident were studied. The gamma-radiation dose rates on the soil surface in the areas varied from 0,02 to 200 mR/h. The frequency of reciprocal translocations in mouse spermatocytes was relatively low and increased linearly with increasing of the dose rate. The levels of recessive lethal mutations in mouse populations did not depend on the radiation dose rate in the areas and decreased with a time.
