Study of Radiation Damage with the Radiation Workers by Low Dose Irradiation

Abstract

Objective To explore the sensitivity index of radiation injury of radiation workers was analyzed and investigate whether the body changes and radiation doses of workers exposed to low-dose radiation have a dose-effect relationship. Methods The occupational health monitoring data of radiology staff were analyzed by retrospectively. Results Individual dose monitoring data, interventional radiology workers had the highest average cumulative annual dose, 0.86mSv. Lens opacity has a high detection rate, Compared with the control group, the lymphocyte count was increased. Annual cumulative dose reached 2.04 mSv, and single cycle average dose reached 1.62 mSv, dicentric chromosome was detected. Conclusions Radiation workers have certain radiation damage, and the focus is on those engaged in interventional radiology. The chromosome aberration rate was highest in people with more than 20 years of working life. Annual cumulative dose reached 2.04 mSv, and single cycle average dose reached 1.62 mSv, dicentric chromosome was detected, it suggests that the chromosome aberration analysis is an important index in occupational health monitoring of radiological workers.
