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.
自切尔诺贝利事故发生后,随着时间的推移,细胞遗传学紊乱的发生率有下降趋势。但即使在事故发生数年之后,仍观察到细胞遗传学损伤发生率显著增加,且这一增加显著依赖于放射性污染水平。长期暴露所引发的细胞遗传学紊乱随时间的下降速度,大大滞后于辐射暴露所引发的下降速度。对冬黑麦和小麦连续三代的遗传变异性分析表明,在受污染土地上种植2至3年的作物中,细胞遗传学损伤有所增加。
