This report (HPA-RPD-053) considers the of the HPA intercomparison of passive radon detectors. This methodology provides a simple, reliable and low-cost tool for drawing up radon flux maps useful to both public planners and private individuals, who want to operate safely. Radon Diffusive flux Risk assessment γ-Ray spectrometry Geochemical mapping.
Equilibrium adsorption isotherms are reported for radon and water vapor on two commercial activated carbons: coconut shell Type PCB and hardwood Type BD. The equilibrium data for radon were correlated with a modified Freundlich equation. This work was financed by the Russian Institute of Radiation Hygiene . Thousands of homeowners could be exposed to higher levels of the deadly gas radon than they realise because of a bizarre interaction with the moon. PA Department of Environmental Protection. Documents available from PA DEP: Health Effects of Radon (pdf):.
Radon is an inert gas and diffuses through and emanates from U rich soils and rocks without undergoing chemical reactions. In the case of mining, ore grade, mining methods, ventilation practices and other factors have changed over time.
Residential radon studies experience similar problems in estimating past exposures, because of, for example, changes in heating and .
