摘　　要：该仪器在检测到超过安全剂量的 X(γ)辐射时报警 ,同时对该事件发生的日期、时间、照射持续时间等参数进行记录。该系统利用自然界的射线本底进行自检 ,可及时发现报警记录仪对辐射无响应的故障 ,冗余措施和外接声光报警器的闭环检测 。When X(γ) radiation over threshold dosage has been detected,the instrument will alarm and record the state parameters,including date and time happened,radiation lasting time and others at the same time.The fault no respond to radiation can be found out immediately by continuously measuring the nature background radiation.It is with higher reliability by means of redundancy and feedback.

关 键 词：X-γ射线 报警 记录 可靠性
