Measurement of radon in water by g-ray spectrometry using a HPGe detector has been investigated to determine aquifer characteristics. The radon activity concentration is determined by taking the weighted average of the concentrations derived from g-ray lines associated with Pb and Bi decay. The role of accurate radon data to representatively sample aquifers was also investigated by studying a s...

The literature proves an evident association between indoor radon exposure and lung cancer, even at low doses. This study brings a new approach to the study of children's exposure to radon by aiming to evaluate exposure to indoor radon concentrations in nursery and primary schools from two districts in Portugal (Porto and Bragança), considering different influencing factors (occupation patterns...

The average indoor radon concentration in Finnish flats is 80 Bq/m3. Typically walls have been made using concrete elements. Building materials are the dominant source of indoor radon. However, in the flats of the lowest floor, with a floor slab in direct ground contact, the main source of radon is often the inflow of radon bearing soil air. The number of these ground contact flats is less than...

In 2006, the Joint Research Centre of the European Commission launched a project to map radon at the European level, as part of a planned European Atlas of Natural Radiation. It started with a map of indoor radon concentrations. As of May 2014, this map includes data from 24 countries, covering a fair part of Europe. Next, a European map of geogenic radon, intended to show 'what earth delivers'...

Introduction Recent studies of public underground parking lots showed the influence of radon concentration and the probable discomfort caused by parking cars. Materials and Methods Radon concentration was measured in semi-closed public parking lots in the six governorates of Kuwait, using Durridge RAD7radon detector (USA). Results The peak radon concentration in the parking lots of Kuwait gover...

BACKGROUND Geothermal waters contain, among other components, soluble radon gas. Alpha radioactive radon is a health hazard to humans, especially when it gets into the respiratory tract. SPA facilities that use geothermal water can be a source of an increased radiation dose to people who stay there. Based on the available literature concerning radon concentrations, we assessed exposure to radon...

Online radon and thoron monitors have been developed using ZnS(Ag) detector for continuous monitoring of concentrations in occupational and general environments. Their performance has been tested successfully both in laboratory and field conditions. Special features of these monitors include low cost, high sensitivity and non-interference of humidity and trace gases. The capability of these rad...

It is well known that radon and its short-lived progenies have the most impact to the population effective dose from radioactive sources [1]. Precise and accurate radon monitoring results should be the basis for the establishment of the national reference level and implementation of radon action plans. During the period February and March 2015, Laboratory for Radioactivity and Dose Measurements...
