Lead and zinc ores are the most important natural raw materials widely used in the industry. These types of ores contain different amounts of radionuclides that expose workers to radiation during extraction, transport, and processing. In this study, 22 samples were collected, including 18 samples of lead–zinc ore and 4 samples of mining waste. Specific activities of ²²⁶Ra, ²³²Th, and ⁴⁰K were determined using a high-purity germanium gamma radiation detector (HPGe). The specific activities of corresponding radionuclides in lead–zinc ore samples varied in the range (< 0.21–107.61), (1.91–48.13), and (< 10.16–664.04) in Bq/kg, respectively. According to the European Commission’s dose assessment instruction for workers, the effective dose absorption was calculated for different scenarios, as transport, outdoor storage, and internal storage, which varied from 0.76 to 10.23 µSv/y, 1.05–17.00 µSv/y, and 1.20–19.20 µSv/y, respectively. For all lead–zinc ore samples, effective doses in various scenarios were lower than the intervention level (1.0 × 10³ μSv/y) determined by the International Commission on Radiological Protection.

铅和锌矿石是工业中广泛使用的最重要的天然原料。这些类型的矿石包含不同量的放射性核素，这些放射性核素在提取，运输和加工过程中使工人暴露于辐射中。在这项研究中，收集了22个样品，包括18个铅锌矿石样品和4个采矿废料样品。具体活动²²⁶镭，²³² Th和⁴⁰使用高纯度锗γ辐射探测器（HPGe）确定K。铅锌矿样品中相应放射性核素的比活度分别以Bq / kg为范围（<0.21–107.61），（1.91–48.13）和（<10.16–664.04）。根据欧洲委员会针对工人的剂量评估说明，针对运输，室外存储和内部存储等不同情况计算了有效剂量吸收，范围从0.76到10.23 µSv / y，1.05-17.00 µSv / y和1.20。分别为–19.20 µSv / y。对于所有的铅-锌矿石样品，有效剂量在各种情况下均高于干预水平（1.0×10低³通过在国际放射防护委员会确定微西弗/ Y）。
