摘要: 为建立四川省铅锌矿放射性水平数据档案,对全省33家铅锌矿企业开展了放射性水平调查,调查了铅锌矿区陆地γ辐射剂量率和矿物放射性核素活度浓度(238U、226Ra、232Th)。根据调查结果进行剂量估算,均低于职业人员年剂量限值20 mSv;开采企业的年受照射剂量最大,冶炼企业的年受照射剂量最小;受照射剂量主要为γ外照射剂量。调查结果可为铅锌矿的放射性污染治理提供数据支持。

Abstract: In order to establish the data archive of radioactivity level of lead and zinc mines in Sichuan province, radiation level of 33 lead and zinc mines in Sichuan province was investigated, and the terrestrial gamma radiation dose rate and mineral radionuclide activity concentration (238U, 226Ra, 232Th) were studied. According to the investigation results, all the estimated dose was lower than the annual dose limit of 20 mSv for occupational personnel. The annual exposure dose of mining enterprises is the highest, and that of smelting enterprises is the lowest. The radiation dose was mainly from γ external exposure. The results show that it is necessary to strengthen the radiation safety management of lead-zinc mining enterprises and strengthen the external radiation protection of employees, which can provide data support for the control of radioactive pollution in lead-zinc mines.

Key words: lead-zinc ore, the level of radioactivity, survey
