淋巴细胞微核率检查同染色体畸变检查一起被认为是两个比较敏感的生物学指标。实验结果表明 ,在一定的剂量范围内 ,微核发生率与剂量间呈明确的剂量效应关系[1,2 ] ,不同的剂量对受照动物外周血淋巴细胞微核率引起不同的影响。1　实验方法1 1　动物　雄性健康新白玉兔 5只 ,体 Lymphocyte micronucleus test together with chromosomal aberration test is considered to be two more sensitive biological indicators. The experimental results show that in a certain dose range, the incidence of micronuclei and the dose showed a clear dose-effect relationship [1,2], different doses of irradiated animal peripheral blood lymphocytes micronuclear rate caused by different effects. 1 experimental methods 1 1 animal male health New White Rabbit 5, body
