Radon. Methods of measurement and Concentration Reduction in Various Spaces

Radon is a radioactive gas of natural origins, coming from the disintegration of uranium from the soil, which concentrates in confined places. It is present in soils, water, building materials and can be transported through porous media, especially by convection and diffusion. The COUNCIL DIRECTIVE 59/2013/EURATOM of 5 December 2013 laying down basic safety standards for protection against the danger arising from exposure to ionizing radiation addresses radon at workplaces and at homes. Radon is directly mentioned in the Basic Safety Standards Directive through Article 54 "Workplace Radon levels", also Article 74 is concerning about "Indoor Radon levels" and the Article 103: "National action plan". The new Directive brings significant changes, with respect to the former Directive 96/29 EURATOM, in terms of protection measures related to exposures due to inhalation of Radon progeny not only in work environments but also in dwellings. Romania, having the status of a EURATOM/EU member, has to implement the directive requirements.
