Age-dependent annual effective dose estimations of 226Ra, 232Th, 40K and 222Rn from drinking water in Baling, Malaysia

Natural radioactivity and radon concentration were studied in drinking water samples from Baling area, Kedah, Malaysia, using HPGe and RAD-7 detectors, respectively. Average concentrations obtained for 226Ra, 232Th, 40K and 222Rn were 44.2 ± 3.9, 38.1 ± 5.0, 140.9 ± 10.6 mBq l−1 and 5.7 ± 0.68 Bq l−1, respectively. Cumulative annual effective doses due to ingestion of 226Ra, 232Th, 40K and ...

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 ...

Testing for Radon Recommended in all Properties

According to the U.S. Environmental Protection Agency (EPA), nearly 1 in 15 homes in the United States are believed to have elevated radon levels. The only way to know for sure is to have the home tested. Radon is an invisible radioactive gas that ...

Range Extender

The Range Extender mixes fresh air with sample air to reduce the concentration of radon in the air fed to the RAD7 radon detector by an order of a magnitude, greatly increasing its effective range. The extender consists of two parallel capillary tubes joined at one end to the outlet hose connector. Fresh air is fed to the input of one tube while the incident radon sample is fed to the other. A ...
