摘要 文章采用大体积内充气正比计数管能谱法测量3H的活度,结合LLC方法,降低了系统的最小探测限MDC;基于能谱法测量3H的活度减少了实验和数据分析的工作量。还研究了基于能谱分析的阈修正、端效应修正和壁效应修正方法。研究方法对放射性气体活度测量装置的升级改造有参考意义。 Spectrum method for activity measurement of 3H with large volume internal gas proportional counter is studied in our work. Combined with LLC method, the MDC of activity measurement instruments is cut down. Furthermore, analysis of experimental data of this method is also studied. With this method, experimental work and data analysis can be decreased. This research provides an enhanced activity measurement of radioactive gas, which is significant for improving activity measurement instruments of radioactive gas.
