A study of 222Rn/220Rn exhalation rate and indoor 222Rn/220Rn levels in higher Himalayan terrain

Radiation Protection Dosimetry
Abstract The noble radioactive gas radon and its isotope thoron dominate terrestrial radiation in the indoor environment. These gases eventually disintegrate generating radioactive ions that readily adhere to aerosol particles. This study was conducted in a tectonically active location with significant radon concentrations.

An ionization chamber for 222Rn measurements

Nuclear Instruments and Methods, 1973
Abstract A 4-1 ionization chamber for 226 Ra determination is described. By measuring the activity of 222 Rn in secular equilibrium with 226 Ra, the 226 Ra activity of a sample can be determined. The sample is kept in a flask for about one month to achieve secular equilibrium.

Determination of Waterborne 222Rn Concentrations Using AC Canisters

Health Physics, 1995
A method for measuring 222Rn concentration in water using charcoal canisters is presented. 222Rn is transferred within a few minutes from water contained in a 0.720 L bottle to a charcoal canister using a portable degassing unit. In the laboratory, gamma counting is performed at least 10 h after sampling to determine waterborne 222Rn concentration. The

Present status of 222Rn in groundwater in Extremadura

Journal of Environmental Radioactivity, 2008
Radon-222 was measured in groundwater sources of Extremadura (Spain), analyzing 350 samples from private and public springs, wells, and spas by liquid scintillation counting (LSC) and gamma spectrometry. The 222Rn activity concentrations ranged from 0.24 to 1168 Bq L(-1). The statistical analysis showed a log-normal distribution with a mean of (111+/-7)
