“…Health risks due to radon in drinking water in US have been studied (Hopke et al 2000). Radon consumed in water appears to rapidly enter the bloodstream from the stomach, (Crawford-Brown 1989) perfusing all the cells of the body (Gosink et al 1990). Several studies have found that radon is removed from the body with a primary half-time of between 30 and 70 min, with a smaller component (possibly that associated with fatty tissue)`having a half-time on the order of several hours (CrawfordBrown 1989(CrawfordBrown , 1991.…”

The paper presents the results of radon concentration measurements in the vicinity of water, indoor air and in contact to building walls. The investigations were carried out using CR-39 track detectors. Samples of ground water flowing out of many springs mostly in Arabian Gulf area except one from Germany have been studied. The results are compared with international recommendations and the values are found to be lower than the recommended value. Measuring the mean indoor radon concentrations in air and in contact to building walls in the dwellings of Kuwait University Campus were found 24.2 +/- 7.7, and 462 +/- 422 Bq m(-3) respectively. These values lead to average effective dose equivalent rates of 1.3 +/- 0.4 and 23 +/- 21 mSv year(-1), respectively.

“…The alpha dose from drinking naturally radioactive water is primarily due to the presence of uranium decay chain nuclides, including Ra-226, Rn-222, Po-218 and Po-214 (1)(2)(3)(4). Of these radionuclides, radon most easily escapes from the surfaces of cracks in rocks and from the surfaces of sediment grains to enter ground water, because radon is a noble gas.…”

“…Several studies have suggested that radon dissolved in the home water supply can substantially contribute to the indoor radon of the home (2,3,5). Subsequent studies have estimated that a water supply with a radon concentration of 10,000 pCi/L would add about 1 pCi/L to the indoor radon due to the outgassing of the domestic water supply (1,6).…”

In north-central Virginia and south-central Maryland, municipal water supplies obtained from reservoirs provide radon-free potable water. However, about 10 percent of the population consumes well water. Radon in drinking water from some wells exceeds 4,000 pCi/L. Only about 30% of the radon is lost between the well storage tanks and the homes. The average radon concentration is about 2,000 pCi/L, which greatly exceeds the U.S. Environmental Protection Agency's recommended Maximum Contamination Level of 300 pCi/L. In this study of a geologically diverse area, the well water comes from granite (radon averages about 3,000 pCi,/L), schist and phyllite (about 2,000 pCi/L), sandstone (about 1,500 pCi/L), and quartzite (about 1,100 pCi/L). Aeration experiments on well water in storage tanks indicated that about 60-70% can be removed using a splash box with an exhaust fan on the storage tank, and about 60-70% can be removed using bubble aeration. About 90% of the radon can be removed by the simultaneous use of bubble aeration, splash box, and an exhaust fan. However, this combination does not become less efficient through time. Passing the water through tanks of activated charcoal can remove about 90% of the radon, though the charcoal becomes less efficient over an interval of a few months.

“…Environmental Protection Agency has recommended that citizens avoid living in homes with indoor radon in excess of 4 pCi/l. The concern has intensified since the discovery that inhaled radon and its progeny pass from the lungs into the blood and body tissues [Pohl and Pohl-Ruling, 1967;Lykken and Ong, 1989;Gosink et al, 1990;Henshaw et al, 19901; and may initiate many types of soft tissue cancers.…”

Seasonal indoor radon variations related to precipitation

Indoor radon concentrations show a strong dependence on weather. Winter tends to be associated with higher than average indoor radon, and summer with lower than average. However, in northern Virginia, the summer of 1988 was wetter than the summer of 1987. Consequently, the regional indoor radon during the summer of 1988 was about 30% higher than during the summer of 1987, and indoor radon during the summer of 1988 actually exceeded the indoor radon level of the 1987-1988 winter.
