Radon High Risk Areas

Virginia has a high concentration of radon. Buildings in a high radon area constructed since 1998 must have a radon barrier in place; The arrangement of geology across northern ireland is such that rock types that are more prone to radon production, such as granite, limestone and mudstone, occur mainly in.

There is no known “safe” level of radon, but the lower the concentration you are exposed to, the lower the risk to your health. Lung cancer risk is higher for smokers due to synergistic effects of radon and cigarette smoking. Statistics released last week show that vast swaths of land in south roscommon are in the highest risk brackets, with one in five homes likely to have high radon levels.

The map of radon zones was developed in 1993 to identify areas of the u.s.

Radon is estimated to cause between 3% to 14% of all lung cancers in a country, depending on the national average radon level and smoking prevalence. Each blocky area you see on a radon maps is a 1km grid square that will have a designated risk for the whole area. The chances of a higher level depend on the type of ground. The darker the colour the greater the chance of a higher level.
