We determine the radon index of land throughout the country. Mostly in the Kralovehradecky region, Trutnov, Jičín and Náchod districts, also locations in Prague, Pardubice, Liberec and South Moravia regions.

We deal with radon measurements. We carry out the implementation of building insulation against radon and prepare measurement reports. We offer hot-air automatic insulation against water, moisture and radon, weekly measurements of radon in the building for renovations, approvals and verification of the effectiveness of the measures.
