Abstract

Global temperature increase leads to thawing of permafrost that protects local populations from radiation exposure by blocking radon-222 migrating into dwellings. This study aims at assessing the effects of permafrost thawing on the concentrations of radon in indoor air. An approach is developed to predict the evolution of the ²²²Rn concentrations by various processes including radon exhalation from thawed soil. It is found that as frozen soil thaws, more radon can enter dwellings, increasing the concentration of ²²²Rn in indoor air and elevating radiation-induced health risks. This study provides useful insight that will enhance understanding of potential climate change effects.
