由中国核工业总公司科技部与中国核仪器设备总公司联合主持召开的技术鉴定会上,顺利地通过了由中国原子能科学研究院和北京核仪器厂联合研制的FH1936型环境γ谱仪系统的鉴定。 经测试和审查,会议认为FH1936型环境γ谱仪具有以下特点和性能: (1) 结构简单,操作简便,一机多用的优点。作野外测量可快速给出环境辐射场总γ空气吸收剂量率,同时给出铀、钍、镭、钾各核素的含量;作室内测量时,可进行环境样品由铀、钍、镭、钾和~(137)Cs等核素分析。该谱仪工作性能稳定,不仅适用于环境辐射监
At the technical appraisal meeting jointly held by the Ministry of Science and Technology of China National Nuclear Corporation and China Nuclear Instrument Corporation, the FH1936 environmental γ spectrometer system jointly developed by China Institute of Atomic Energy and Beijing Nuclear Instrument Factory Identification. After testing and review, the meeting held that the FH1936 environment γ spectrometer has the following features and performance: (1) the structure is simple, easy to operate, the advantages of a multi-purpose machine. For the field measurement, the γ radiation absorption rate of the ambient radiation field can be quickly given, and the contents of uranium, thorium, radium and potassium radionuclides are also given. For indoor measurement, the environmental samples can be prepared from uranium, thorium, radium and potassium And ~ (137) Cs and other nuclide analysis. The spectrometer working performance is stable, not only for environmental radiation monitoring
