  • Radon distribution in groundwater of Taiwan

    Radon levels were surveyed in 517 monitoring wells constructed in five major groundwater areas of Taiwan. The radon concentration in groundwater samples varied in a wide range from below the detection limit of 18 pCi/L up to 1,100 pCi/L. A worldwide comparison of reported groundwater radon levels was conducted. Overall radon levels in Taiwan groundwater are relatively low compared to other ...

  • Czech studies of lung cancer risk from radon

    Epidemiological evidence of lung cancer risk from radon is based mainly on studies of men employed underground in mines. One such study among uranium miners was established in 1970 by Josef Sevc. During the 1980s, another occupational study followed. In 1989, Sevc designed a new large cohort study among inhabitants exposed to high radon concentrations in homes. The paper reports recent results ...

  • Development of an economical radon-resistant construction technique that is applicable in national radon-reduction programmes

    Radon is believed to be an important risk factor for lung cancer. Radon levels in some regions of Ramsar, a city in northern Iran, are up to 3700 Bq/m³. On the other hand, in the hot springs of Mahallat, in the central part of Iran, the indoor mean radon concentration in air is as high as 480 Bq/m³. In order to develop an economical radon-resistant construction technique, the radon-reducing ...

  • A simple radon chamber for use with soil gas for calibration of radon measuring devices and instruments

    A simple and easy to use radon calibration chamber of volume of 216 litres was designed and constructed for applications in calibration of radon measuring devices and for research studies. The main advantage of this chamber is that instead of using 226Ra source to generate the 222Rn inside the chamber, ...

  • The investigation and measurement of the radon gas working level inside buildings in Rafsanjan

    Radon gas and its daughters are radioactive and radiate alpha particles with high energy. These particles can cause DNA damage, which may or may not be properly repaired. Also, if these particles get into the lungs for a long period of time, they may damage the lungs' inner tissue. This is one of the most important causes of lung cancer after smoking. This paper presents a report on the ...

  • Radon-222 from different sources of water and the assessment of health hazard

    Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water. The radon concentrations were in the range of 3.56–98.57, 0.88–25.49, 0.73–1.35 and 0.24–1.03 Bq.L−1 for borehole, well, packaged and utility water, respectively. Samples from boreholes had the highest radon concentrations with about 67% ...

  • Estimating the spatial-temporal distribution of Radon releases from the K-65 silos

    This study investigates the spatial and temporal distribution of Radon at the Department of Energy's (DOE) Fernald Environmental Management Project (FEMP), in southwest Ohio in 1999. It employs the United States Environmental Protection Agency's (EPA) Industrial Source Complex Short Term 3 (ISCST3) dispersion model, existing monitoring data and Geographic Information Systems (GIS) as tools to ...

  • The study of radon levels and absorbed dose in the staff and visitors of Alisadr Cave

    CR-39 passive integrating Solid State Nuclear Track etch Detectors (SSNTDs) were used to measure atmospheric radon concentrations in the Alisadr show cave in Hamedan province, Iran. This was done in order to assess the risk from natural environmental radiation to tourists and cave guides. The study was carried out in 12 locations in the winter and spring periods. The mean radon concentration ...

  • Radon Levels in Dwellings of New Mirpur Azad Kashmir, Sub-Himalayas, Pakistan

    Radon concentrations were measured in kucha, semi-kucha and pucka houses located on the sedimentary rocks of Early Pleistocene-Pliocene Soan Formation, Pleistocene Mirpur conglomerate and recent deposits. The radon concentration was measured using CN 85 nuclear tracks etch detectors in box type dosimeters installed in the bedrooms and kitchens of the houses. It was found to vary from 14 ± 7 Bqm-3 ...

  • 3 things architects and engineers should know about Radon

    1.New buildings: how can engineers and architects predict radon levels Testing is the only way to know a building’s radon levels. At present, there are no reliable, easily applied and inexpensive methods that could conclusively identify problem sites and predict if a new building will have high indoor radon levels. There are a lot of factors that cause elevated indoor radon ...
