摘要
本文介绍了地浸采铀过程中氡的释放特点、空气中氡的浓度水平、职业照射剂量水平及其相应的控制标准等。从空气污染预防与控制、事故应急、环境管理等方面总结和提出了控制地浸采铀过程中氡浓度的有关对策和措施,并对2个有关降氡典型实例进行了分析。这将有助于降低地浸采铀职业照射有效剂量,保障地浸采铀职业健康安全和保护环境。
The radon release characteristics and radon concentration levels in the air,average occupational effective dose levels as well as relevant standards for radiation protection in China were introduced during in-situ leaching of uranium. The measures to control radon concentration and reduce radiation exposure of radon from the air pollution prevention and control, accident emergency, to environmental management practices during in-situ leaching of uranium were summarized. In addition,two related typical cases were discussed. This will help to reduce average occupational effective dose,to protect occupational health and surrounding environment during in-situ leaching of uranium.
