The effects of positive and negative ions on the lung dose from environmental radon

The variations of a number of properties relation to radon as a result of the application of positive and negative ion generators have been investigated. These properties include the radon concentration, the total potential alpha energy concentration of radon daughters, the equilibrium factor and the fraction of unattached radon daughters. From the data collected in the present investigation, the mean annual equivalent dose values due to the inhalation of indoor air have been calculated for the bronchial basal cell layer, the pulmonary and the total lung according to the ICRP 32 (1981). Comparisons have also been made for the dose values obtained for the application of positive and negative ion generators with that for untreated air. (Author)
