Abstract:
Objective To quantitatively investigate the effect of low-dose ionizing radiation on the frequencies of chromosome aberrations and micronucleus-containing cells of radiation workers.Methods Nine electronic databases were systematically searched on the basis of the published studies evaluating the effects of low-dose ionizing radiation on the frequencies of chromosome aberrations and micronucleuscontaining cells.Of the 195 studies searched,21 studies were identified with a total of 1 970 626 cells under studying.Cochrane' s Q and I2 statistics were used to evaluate heterogeneity among studies and pooling odds ratio (OR) with 95％ confidence intervals (CI) were calculated using random-effect models or fixed-effect models,and publication bias were also calculated.Meta-analysis was performed using Stata 12.0.Results The pooling OR of chromosome-type aberrations [OR =3.03 (2.59,3.56)],dicentric plus centric rings [OR =4.12 (2.99,5.67)],translocations [OR =2.73 (1.67,4.46)],micronucleuscontaining cells [OR =1.70 (1.40-2.06)] were higher for radiation workers when compared with control group.Conclusions The frequencies of chromosome aberrations and micronucleus cell of peripheral lymphocytes are significantly high in radiation workers who were occupationally exposed to low-dose ionizing radiation.It should be noted that the radiation protection of radiological workers be enhanced.
