为了解特殊环境中反应堆周围工作人员体内放射性的含量，我们对某一核反应堆周围连续工作和生活35昼夜的工作人员（放射组）和一般环境中正常工作和生活的人员（对照组）进行尿总β放射性比较测量。现将测量情况报告如下：1方法与步骤1．1方法与原理采用化学方法将尿中钾-40与 In order to understand the radioactive content of the workers around the reactor in a special environment, we conducted a survey of the total urine and urine of staff and workers working 35 days and nights around a nuclear reactor (radiation group) and the normal working and living environment (control group) Beta radioactivity measurement. Now the measurement report as follows: 1 Methods and Procedures 1.1 Methods and Principles The use of chemical methods to urine potassium -40 and
