Radon progeny aerosol control device and related metrological research

With the construction and development of nuclear facilities, many nuclear production sites need to monitor artificial radioactive aerosol. However, radon and its daughters are ubiquitous in the environment, and their concentration levels are considerably higher than those of artificial radioactive aerosols. Therefore, artificial radioactive aerosol monitors can reliably measure environmental artificial radioactive aerosol only by testing the effectiveness of radon daughter compensation. By studying the mechanism of radon progeny aerosol and establishing a radon progeny aerosol control device that meets the measurement standards, the concentration of radon progeny aerosol in a radioactive aerosol monitor in certain places can be corrected. Thus, the interference to the measurement of specific radioactive aerosol can be reduced in the high radon environment of such places. In this study, we established a radon progeny aerosol control device that can be used to compensate the radon daughter aerosol for the radioactive aerosol monitoring equipment and help to eliminate or reduce the radon progeny aerosol interference of the radon daughter aerosol correction radioactive aerosol monitoring equipment.
