determining the integral value of annual effective dose from 222Rn for workers of the granite mining industry and assessment for the expected life effective dose from 222Rn.
Materials were the results of measurements of external exposure dose of radiation measurements equiv alent equilibrium volume activity of 222Rn in workrooms and workplaces of major groups of granite quarry workers Mykolaiv region, studies EROA 222Rn air premises of these workers, research content 222Rn in drinking water.
Granite quarry workers receive double radiation exposure of 222Rn due to exposure in the workplace and at home. The load in the workplace due to inhalation of 222Rn the air was (2.1 ± 0.2) mSv / year (vari ation 0.9-5.9) in a residential area - (4,1 ± 0,2) mSv/year (variation 1.8-5.9). The total annual effective dose from internal exposure from air flow and working premises and drinking water was on average (6,5 ± 0,2) mSv/year, equal to a maximum value of 20 mSv/year. The expected life for the chronic exposure dose of technological naturally occurring radioactive sources for people who work in the granite quarries and, while living in high risk from radon is in the range of 0.16-1.12 Sv. The research results indicate that in assessing the effects associated with exposure due to radon 222 contingents persons such surveys must take into account all sources of this radionuclide dose.
确定花岗岩采矿业工人因222Rn产生的年有效剂量积分值，并评估其预期寿命内的有效剂量。
材料包括对尼古拉耶夫地区花岗岩采石场主要工种工人工作间和工作场所222Rn等效平衡体积活度的辐射外照射剂量测量结果、这些工人工作场所空气中222Rn的研究结果、饮用水中222Rn的研究内容。
花岗岩采石场工人因在工作场所和家中接触222Rn而受到双重辐射照射。工作场所因吸入空气中的222Rn产生的负荷为（2.1±0.2）mSv/年（变化范围0.9 - 5.9），在居民区为（4.1±0.2）mSv/年（变化范围1.8 - 5.9）。来自气流、工作场所和饮用水的内照射年总有效剂量平均为（6.5±0.2）mSv/年，最大值为20 mSv/年。对于在花岗岩采石场工作且生活在氡高风险环境中的人群，技术天然放射性源慢性照射剂量的预期寿命在0.16 - 1.12 Sv范围内。研究结果表明，在评估与222Rn照射相关的影响时，此类调查必须考虑该放射性核素剂量的所有来源。
