CRITERIA FOR INDOOR RADON CONCENTRATION - AN EXPERIMENTAL-STUDY CONSIDERING ESPECIALLY THE LEIPZIG-HALLE BROWN-COAL AREA

The project is supported by the EU-programme Human Capital and Mobilit y, The project intends to improve the understanding of the specific be haviour of the radon gas. The research will consequently focus on para meters or effects affecting radon concentration levels and their varia tion in buildings as a function of existing and previous variations of radon in the underground, in addition to the radon component from the building materials and environmental artificial radon sources coming from industrial processes like mining and metallurgy. The programme is to carry out an intercomparisonal experimental survey Lund-Kiel-Leipz ig-Montpellier-Barcelona-Rome including both regular dwellings and ins trumented ''test houses'' under various meteorological, geological and environmental conditions including the habits of the inhabitants. The radon levels will be measured indoors and in the subsoil using both t rack films and electronic devices. This should lead to a general model pertinent to variations of the radon concentration in houses.
