Design of intelligent sampler for large flow total suspended particulates

Abstract

For the current nuclear radiation problem in society, it is very important to monitor the content of radionuclides in the atmosphere. The large flow total suspended particulate (TSP) sampler is the key equipment to monitor radionuclides. In this paper, a large flow total suspended particulate intelligent sampler is developed, which has high sampling accuracy, stable and reliable operation, and forms a complete set of automatic membrane changing particulates matter analyzer with analyzer and membrane sending mechanism, realizing 24-hour unattended automatic membrane changing sampling and analysis, and is used to collect suspended particulate matter in air in radiation monitoring stations and scientific research institutes at all levels to analyze the radionuclides: total α, β and γ and so on.
