本文对30名临床放射性工作者和20名对照者的骨髓有核红细胞微核细胞率观察结果表明放射组微核细胞率的增高较对照组有极显著意义(P<0.01);并发现放射组中男性与女性微核细胞率的差异极显著(P<0.01);放射工龄的长短与微核细胞率的高低无显著性差别(P>0.05) In this paper, 30 clinical radionuclides and 20 controls were observed in bone marrow nucleated erythrocyte micronuclei rate showed that the increase in the rate of micronuclei in radiotherapy group than in the control group has a very significant (P <0.01); and found that the radiation group There was significant difference in the rate of micronucleated cells between male and female (P <0.01). There was no significant difference between the length of radioactive service and the rate of micronucleated cells (P> 0.05)
