- Abstract
When monitoring radioactive aerosol in the atmosphere, choosing a filter membrane with better surface collection characteristics and filtering efficiency will facilitate the improvement of the monitoring efficiency. In this paper, a developed calibration system for radioactive aerosol monitor was improved. A measurement device for filtering efficiency of filter membrane is added to the sampling and measurement unit. The device is tested using several commonly used filter membranes, and the measurements were compared with a general method. The results showed that the measurement proposed in this paper can quickly and accurately measure the filtering efficiency of various filter membranes. The deviation from general method is less than 2%.
