Health risk by radon in drinking and sanitary water: assessment and control techniques

This paper is to inform people about a recently known hazard for drinking and sanitary water, which is still not well investigated as it is only in the last six years that scientific people have been aware of the problem and began to face it seriously: water pollution by Radon (Rn) radioactivity. To this aim are shown dangerous health effects proved by scientific investigations carried out in many countries, the main theories an formula coming from both different theoretical and experimental research to measure Rn concentration in water. The last proposal, coming from both authoritative searches and organisation, to fix health safety concentration level. Finally, it is proposed to establish the first limit of Rn concentrations in water to assure human safety and some control techniques to reduce Rn concentration below the reference safety limit.
