Levels of Nanosize Radon Decay Products in Indoor Air: A Comparison for Different Environments
Janja Vaupotič
Abstract
The fraction of unattached (fun) nanosized 222Rn short-lived decay products in indoor air has been measured in different
environments and the following ranges obtained: 0.03–0.25 in kindergartens, 0.03–0.18 in schools, 0.08–0.20 in wineries,
and 0.12–0.68 in a karst cave. The dependence of fun on the environmental conditions (air temperature, relative humidity
and pressure), as well as on the working regime has been studied and will be discussed. Applying the dosimetric
approach, dose conversion factors were calculated, based on the measured fun values, and compared to the values, obtained
from epidemiological studies and currently recommended to be used in radon dosimetry.
