Especially Some radioactive nuclides are carried to the nuclear radiation pollution. So studying the performance of radioactive detection system is more important. on paper,12 types of radioactive detection system directly property were searched, and Anglicizing each performance parameters directly in the inspection system of radioactive represents meaning. Finally the each detection system of each performance parameters of the performance parameters of the table is made. Directly to the same radioactive detection system for example, We should Consider each of its performance parameters on the test system performance impact; To different types of radioactive detection system of the same directly for performance parameters, differ Size performance parameters decided the testing system of different detection efficiency. So deciding to a radioactive detection system directly the performance of the main parameters are The detector, Energy response range, sensitivity, System detection probability, system error alarm rate, Working temperature and humidity range and Data collection time. Key words：The channel radiation detection system; performance parameter; nuclear; radioactive nuclide l 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc326267701 1.绪 论 PAGEREF _To
