[An analysis of the cytogenetic sequelae of chronic low-dose irradiation in plantings of agricultural crops].
There is a tendency for a decrease in the yield of cytogenetic disturbances with time elapsed from the Chernobyl accident. But an increased rate of cytogenetical damages significantly dependent on the level of radioactive contamination was observed even in several years after the incident. The rate of decline with time in cytogenetic disturbances induced by chronic exposure considerably lagged behind that of radiation exposure. Analysis of genetic changeability in three sequential generations of winter rye and wheat revealed increased cytogenetic damage in crops grown on contaminated sites during 2 and 3 years.
