环境氡子体剂量通常是根据环境氡暴露量和推荐的氡子体平衡因子F来估算的。为了研究PM2.5与氡子体平衡因子的关系,用香烟模拟多功能氡室中的雾霾,以获得稳定的氡浓度环境。使用测氡仪和便携式激光气溶胶光谱仪获得了PM2.5、CRN和Cp的平均值。结果表明,F的平均值符合联合国原子辐射效应科学委员会推荐的典型数值,在0.1-0.9的合理范围内。在这项研究中,F值与PM2.5浓度呈正相关。
AbstractThe 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 Cmean PM2.5, CRn, and Cp. 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.
