Which countries have the lowest levels of radon?

Germany, Poland, the Netherlands and the UK will have lower levels, in average, than Austria, Finland, Sweden or Czechia. However, the downside of using geographical expectations is that if your home is built over sedimentary soils, radon can over-concentrate if ventilation is poor.

Which homes should be tested for radon?

All homes should be tested, regardless of zone designation. The purpose of this map is to assist National, State and local organizations to target their resources and to implement radon-resistant building codes.

What is radon and why is it dangerous?

Radon is a naturally occurring radioactive gas that emanates from soil and bedrock, including granite, and can seep into homes primarily through cracks and seams in foundation floors and walls. It may also enter through well water. Radon is a known carcinogen, a substance capable of causing cancer in living tissue.
