辐射安全文化素养探析

安全文化素养是核能界针对两次严重事故后总结提出的新概念新举措,并适用于辐射安全领域。本文在分析安全文化素养概念的基础上,结合我国的辐射安全现状,着重探析辐射安全文化素养建设的必要性、要求及应用发展,并埘医疗行业中存在的问题进行了分析,对培育安全文化素养提出了几点个人的看法。     

Social-Economic Aspects of Radiation Safety

Among the many scientific, technical, and social problems which nuclear power in the past century has encountered, the most significant are economy, safety, and public acceptability.The possibilities of increasing the economic efficiency by using boiling water vessel reactors with natural coolant circulation, the need to take account of not only the dose but radiation intensity when estimating biological effects of irradiation, and the problems of insurance for compensating radiation harm to the health of workers in nuclear cycle enterprises and the population are discussed. 2 figures, 17 references.

核设施安全监管与辐射环境安全监管

从历史沿革、管理对象、技术基础、区域覆盖和监管手段等5个方面比较了核设施安全监管和辐射环境安全监管的区别,分析了二者在根本目标一致性、顶层管理统一性和职能分工互补性上的联系,阐释两种监管共存的意义。     

X射线快速安全检查系统的辐射安全性分析

X射线快速安全检查系统是港口、物流中心、公路卡口等场所对大量进出集装箱货物进行快速安全检查的X射线类检查系统。国内某厂商研制的X射线快速安全检查系统, 采用司机直接驾车通过检查通道的方式来实现对集装箱卡车货物的快速检查, 本文介绍该系统的工作流程, 分析正常工况下司机被系统误扫、人员闯入或藏匿于集装箱中的安全风险, 以及设计基准事故下的安全风险。结果表明, 该系统是安全可行的, 关键人群司机以及意外闯入检查通道的人员所受剂量低于相关标准的要求, 对人员健康无影响。     

医院辐射安全审查中值得注意的一个问题

Technical Developments in Radiation Safety Management

Developments in the field of radiation protection in Japan for the period of these 10 years are reviewed. Radiation dosimeters for practical use, thermoluminescence dosimeter (TLD), glass dosimeter and personal alarm dosimeter, with which remarkable innovations have been made, and dose distribution models as a useful means of exposure control are selected and briefly stated.     

Radiation Safety Considerations for LHD Experiments

For experiments with the Large Helical Device (LHD) which is now under construction at the Toki site in Japan, radiation safety issues were discussed. In the course of plasma experiments, radiations such as X-rays, induced -rays, and neutrons increase. From a safety point of view, these radiation exposures to the environment should be controlled to limit the annual dose to less than 50 Sv at the site boundary. In order to meet this, an area monitoring system named RMSAFE (Radiation Monitoring System Applicable to Fusion Experiments) has been developed and partly installed. This can discriminate and measure radiations including burst-like emissions due to plasma shots from natural radiations. For the present period, this system is operating to monitor the natural radiation levels before the LHD operation. It was observed that the radiation levels strongly depend on rain levels and ground state. An indoor area monitoring system has already been implemented on site, to measure radiations from NBI and ECH test shots, and it shows good monitoring ability. Also, thermoluminescence dosimetry has been applied. The importance of investigating the radiological behavior under natural conditions with continuous monitoring is shown.
