ABSTRACT
Basic considerations
1. Legal base fixing the limiting value for radon in residential and recreational premises.
(Radiological Protection Ordinance of 22 June 1994)
2. Engagement in a campaign measuring the radon concentrations, finding the areas with radon
prone buildings, and mapping those areas.
3. Collaboration with the homeowners living at a high radon concentration to define a project how
to reduce it.
