Abstract

This article presents a comprehensive survey of radon concentrations and associated occupational exposure doses in 110 non-uranium mines across 13 provinces and autonomous regions in China from 2019 to 2021. Using solid-state nuclear track detectors, the study found that underground metal mines had a significantly higher average radon concentration (1180 Bq/m³) and annual effective dose (12.7 mSv) compared to nonmetal mines (162 Bq/m³ and 1.75 mSv, respectively), with 22.6% of metal mines exceeding the national action level limit of 1000 Bq/m³. The findings highlight the need for strengthened ventilation and individual radon dose monitoring in high-radon mines, as well as the adoption of hierarchical management models aligned with international radiological protection standards to better safeguard miners' health.
