Analysis of Radon and Radon Progeny in Residences: Factors that Affect Their Amounts and Methods of Reduction
Abstract
The effectiveness of using an electrostatic precipitator as a means for reducing harmful levels of radon progeny in the home was evaluated. A commercially available precipitator, manufactured by the Honeywell Corporation, was used during the course of the study. The specific model used was the Honeywell Electronic Air Cleaner model number F50A1009. Daughter concentrations were measured by the modified Tsivoglou method. Samples were collected on a 2- inch millipore filter and alpha emissions were measured with a ZnS(Ag) scintillator. A sample collection time of 5 minutes was used. Sample counting intervals of 2-5, 6-20, and 21-30 minutes after sample collection were used. During this study air samples were made using the blower fan and filters alone with no power to the electrostatic precipitator, and with the electrostatic precipitator energized. The reduction in the working level as a result of using the blower fans and filters only was 75 percent. With the electrostatic precipitator energized the reduction level rose to 90 percent. It is therefore concluded that the electrostatic precipitator is an effective means for reducing radon progeny concentrations in the home.
