摘要

Abstract

The dosage of environmental radon progeny is typically estimated according to the environmental radon exposure and the recommended radon-progeny equilibrium factor,F,. To investigate the relationship between PM2.5 and the radon-progeny equilibrium factor, cigarettes are used to simulate the haze-fog in a multi-functional radon chamber to achieve a stable-radon concentration environment. A radon detector and a Portable Laser Aerosol Spectrometer are used to obtain the values for ,C,mean, PM2.5,C,Rn, and ,C,p,. The results show that the mean values of ,F, conform with the typical value recommended by the United Nations Scientific Committee on the Effects of Atomic Radiation and are within the reasonable range of 0.1–0.9. In this study, a positive correlation is observed between the ,F, values and PM2.5 concentrations.
