A high radioactive circumstance measuring system based on current method has been designed in this work. The method avoids saturation caused by pulse overlap in high radioactive circumstance presented in traditional pulse counting method. Meanwhile, the system acquires a wider measurement range under the condition of satisfaction accuracy within ±10%.Experimental test shows that the system has some advantages such as concise design, wide measurement range, fine linearity and accuracy, which can be used in a special filed or area to measure high radioactive circumstance.%介绍了一种采用电流法测量高放射性环境的系统,避免了传统的脉冲计数方法在高放射性环境下出现的过载问题.同时在满足相对固有误差不大于± 10%的条件下,获得了较宽的量程.试验表明,该系统具有电子学简洁,线性好,量程宽,测量精确度高等优点,可用于特殊领域或区域中高放射性环境的测量.
