| Abstract: | The time dependence of energy compensation coefficient was studied for the measurements of radioac -tive aerosol by energy discrimination method.According to the law of radioactive decay on the membrane,the detailed influences of sampling time,waiting time and measurement time were analyzed.Then the experimental validations were operated, and the optimized time assignations were obtained.This research would provide a helpful reference for the rapid measurements of radioactive aerosols. |
