Indoor radon measurements in the city of Valencia
Applied Radiation and Isotopes, 2011The indoor radon risk in Valencia (Spain) was studied more than twenty years ago in two surveys using different methodologies and leading to contradictory results. We report here on new indoor radon measurements with the charcoal canister technique, which confirm the low average level of indoor radon in the city, with a geometrical mean of 24 Bq/m(3 ...

Comparisons Between Soil Radon and Indoor Radon
Energy Sources, 1999Several thousand indoor radon measurements have been obtained for homes in northern Virginia. Compilations of these data according to the geologic units under the homes show that some units have relatively high or relatively low median indoor radon levels, and that these differences persist through all four seasons.

Groundwater treatment as a source of indoor radon
Applied Radiation and Isotopes, 2014New Viimsi Parish water treatment plant (Northern Estonia) was investigated in order to determine whether the open filter columns serve as a source of (222)Rn generation in the treatment process and whether they influence indoor air (222)Rn activity concentrations.

Indoor Radon and Lung Cancer in China
JNCI: Journal of the National Cancer Institute, 1990Radon has long been known to contribute to risk of lung cancer, especially in undergound miners who are exposed to large amounts of the carcinogen. Recently, however, lower amounts of radon present in living areas have been suggested as an important cause of lung cancer.

Evaluation of indoor radon measurements in Hungary
Journal of Environmental Radioactivity, 2006The RAD Laboratory measured annual means of radon activity concentrations in 15 277 first-floor rooms of dwellings and in 325 rooms on upper floors in Hungary (1994-2004). The original purpose of the survey was to find radon-prone area in Hungary. The maximum measured value was 5800 Bq m(-3), while the minimum was 10 Bq m(-3).

Origin and health risks of indoor radon
Seminars in Nuclear Medicine, 1988Radon has always been a component of ground and air and it has been present in increased concentrations from the moment humans first sought shelter inside dwellings. Recent improvements in the energy efficiency of dwellings have led to increased concentrations of radon and to increased risks of lung cancer.

Indoor radon measurements in the Beijing area
Science of The Total Environment, 1991Average indoor air radon concentration of 30 Bq/m3 was determined in various types of dwellings in the Beijing area using activated carbon detectors. In this study, several related factors were also investigated: radon area exhalation rates of 136 building materials and from soil surfaces; Ra-226 contents of 143 soil samples, 34 building materials and ...

Indoor radon measurements in Turkey dwellings
Radiation Protection Dosimetry, 2014In this work, indoor radon radioactivity concentration levels have been measured in dwellings of Turkey within the frame of the National Radon Monitoring Programme. The (222)Rn concentrations were measured with time-integrating passive nuclear etched track detectors in 7293 dwellings in 153 residential units of 81 provinces, and the radon map of Turkey
