Abstract
Radon-222, along with thoron (Rn-220), of the three isotopes of radon, contributes with more than 50% to the dose equivalent to the public coming from natural sources. Radon is a major risk factor for lung cancer occurrence (10-14%, in Europe, p.a.). Previous measurements in Romania show an increased radon risk level, above the European average, while the lack of sustained preoccupation situates us, according to the WHO, among the “weakly radon developed” countries, with respect to the response to this hazard. The geological mapping of radon prone areas has been done, but no systematic measurements exist and no risk management or public information. As part of a joint proposal with the Environmental laboratory of the Babes-Bolyai University, NIPNE intends to participate in a nation-wide program of radon risk assessment covering several geographical regions for indoor radon, radon emanation (soil gas) and water sample study, in summer and winter, associated with public awareness promotion activities and the construction of a radon database. Based on a calibration method for SSNTD developed formerly at NIPNE, we obtained in a series of in-situ measurements indoor radon data in several homes and locations in the Bucharest region, in various buildings, different construction types, materials, distance to the ground level, ventilation conditions.
