Development of maps of radon-prone areas using radon measurements ion houses

摘要

Radon is a radioactive gas arising from the uranium decay chain, and can enter houses form the ground. High radon exposures have been shown to cause lung cancer. Many governments and international bodies have therefore recommended that radon exposures in houses should be limited. Radon levels in houses vary widely from area to area depending on local geology. However, the relationship with geology is complex and varies between rock types, within single Rock types and is affected by superficial cover. Even on a single geology, radon levels vary widely Depending on house characteristics and the living habits of the occupants.
