Development of maps of radon-prone areas using radon measurements in houses.
RISK 97 International Conference. Amsterdam, NLD, 1997/10/21.
Radon is a radioactive gas arising from the uranium decay chain, and can enter houses from 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.
In order to identify houses with high radon levels, it is necessary to map the problem.
In the UK, this has been carried out using lognormal modelling of results of measurements of radon levels in houses around the country.
Such maps have been the basis of advice from NRPB to the government on limiting radon exposures.
Methods of deriving maps at 5 km and 1 km grid square resolution are discussed with examples.
