High residential levels of radon gas have always been a problem in some parts of the Northeast United States, especially in Pennsylvania, but a recent study has found a correlation between the Marcellus Shale natural gas fracking boom and a recent, disturbing spike in residential radon levels. ...
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 ...
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, soil gas is utilised as a source of 222Rn. Soil gas is drawn from the soil using a pump to fill ...
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 ...
