Detection and Analysis of the peripheral lymphocytes micronucleus rate of radiation workers in a city / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To perform lymphocyte micronucleus analysis on radiation workers with long-term exposure to low doses ionizing radiation, Evaluate the health condition of radiation workers, and provide the evidence for strengthening surveillance of radiation workers.@*Methods@#From January 1, 2013 to December 21, 2016, a statistical analysis and evaluation was conducted of the peripheral lymphocytes micronucleus rate in 5 901 radiation workers who had undergone medical examinations of employees at Chinese Academy of Medical Sciences Institute of Radiation Medicine.@*Results@#The micronucleus rates in radiation workers of the on-job group were higher than the pre-job group (P<0.01) . Significant difference was found among the different sex (t=5.97) , different types (χ2=378.69) , different levels of work units (χ2=115.48) . Significant difference was found among the micronucleus rates of 672 radiation workers of the on-job group from 2013 to 2016 (χ2=92.57, P<0.01) .@*Conclusion@#The peripheral lymphocytes micronucleus rate of radiation workers were significantly higher than non-contact workers. Significant increasing trend of micronucleus rates was noted among the radiation worker with increasing exposure time. The peripheral lymphocytes micronucleus rates of interventional therapy workers were highest. The peripheral lymphocytes micronucleus rates of Private hospitals workers were highest. This phenomenon deserves attention. Protection needs to be strengthened to ensure the health of radiation workers.
