| Abstract:: |
| Objective To investigate the radon exposure levels and health effects among non-uranium miners in Chongqing. Methods From June 2022 to December 2023, a survey was carried out on basic information, radon exposure and occupational health status of 110 male miners with good cooperation attitudes in 6 non-uranium metal mines in normal operation in Chongqing. The logistic regression model was utilized to statistically analyze the impact of miners' individual radon doses on abnormalities in chromosomal aberration analysis, micronucleus examination, tumor marker tests, and pulmonary CT imaging. Results Monitoring results from passive integrated radon personal dosimeters indicated that three miners had an annual dose exceeding 2 mSv. Logistic regression analysis revealed that abnormalities in pulmonary CT imaging were associated with miners' age, tenure, and alcohol consumption (χ2 = 12.18,9.63,4.87, P ＜ 0.05), with no significant correlation with smoking or individual radon dose. There was a significant correlation between individual radon dose and abnormalities in tumor markers; for every additional 1 mSv of effective dose from radon and its progeny, the risk of abnormality increased by 2.25 times (χ2 = 4.57, P < 0.05). Conclusions Some miners in Chongqing are exposed to an annual dose exceeding 2 mSv, and there is a correlation between individual radon doses and abnormalities in lung cancer serum tumor markers. It is necessary to focus on monitoring the radon exposure risks for miners, carry out regular health checks, and enhance the health protection for the miner population. |
