Abstract
The quantitative relationships between radon gas concentration, the surface-deposited activities of various radon progeny, the airborne radon progeny dose rate, and various residential environmental factors were investigated through a Monte Carlo simulation study based on the extended Jacobi room model. Airborne dose rates were calculated from the unattached and attached. potential alpha-energy concentrations (PAECs) using two dosimetric models. Surface-deposited Po-218 and Po-214 were significantly correlated with radon concentration, PAECs, and airborne dose rate (p-values <0.0001) in both non-smoking and smoking environments. However, in non-smoking environments, the deposited radon progeny were not highly correlated to the attached PAEC. In multiple linear regression analysis, natural logarithm transformation was performed for airborne dose rate as a dependent variable, as well as for radon and deposited Po-218 and Po-214 as predictors. In non-smoking environments, after adjusting for the effect of radon, deposited Po-214 was a significant positive predictor for one dose model (RR 1.46, 95% CI 1.27-1.67), while deposited Po-218 was a negative predictor for the other dose model (RR 0.90, 95% Cl 0.83-0.98). In smoking environments, after adjusting for radon and room size, deposited Po-218 was a significant positive predictor for one dose model (RR 1.10, 95% CI 1.02-1.19), while a significant negative predictor for the other model (RR 0.90, 95% CI 0.85-0.95). After adjusting for radon and deposited Po-218, significant increases of 1.14 (95% Cl 1.03-1.27) and 1.13 (95% CI 1.05-1.22) in the mean dose rates were found for large room sizes relative to small room sizes in the different dose models.
