Radiation monitoring equipment give alarm signal according to the radiation intensity; monitoring the current count and the background average count, and gives a warning signal when the difference between the two over a certain range. 放射性监控仪器一般是根据辐射场强度变化量的大小给出报警信号,通常将探测器当前计数与本底平均计数进行比较,当两者的差值超过一定的范围,就给出警示信号。
Based on the radiation protection monitoring, the radiation protection of a 2.8 PBq 60 Co irradiation equipment run about ten years are summarized and assessed. 从辐射防护角度,对一座2.8PBq60Co辐照装置运行近10年的辐射安全进行总结与评价。
Small advantages of optical imaging method compared with other imaging modalities include the use of non-ionising low energy radiation, high sensitivity, capability of continuous data acquisition for real-time monitoring, no substrate, and the development of potentially cost-effective equipment. 该方法相对于其它分子成像方法而言具有明显的优势:非电离低能量照射、高灵敏度、实时、非侵入性、无需放射试剂以及成像系统费用低。
