“…The methodology used to collect water samples from wells and springs for radon analyses generally followed guidelines established by the USGS (Wood, 1981;Claassen, 1982;and Cecil and Gesell, 1992). Equipment used to collect water from wells included a short, flexible piece of tubing inserted into a 1,000-mL beaker, a 20-mL glass or polyethylene hypodermic syringe with an 18-gage stainless steel hypodermic needle, and two glass scintillation vials per sampling site with 10 mL of mineral-oil based liquid-scintillation solution in each.…”

Concentrations of dissolved radon-222, a naturally occurring radioactive gas, are found in water in Idaho. The U.S. Geological Survey collected water samples for radon-222 analyses from 338 Idaho wells and springs during 1989-91. These water samples were collected as part of ongoing monitoring programs with the Idaho Department of Water Resources and the U.S. Department of Energy. Concentrations of dissolved radon-222 in 372 of the water samples ranged from-58±30 to 5,715±66 picocuries per liter; the mean and median concentrations were 446±35 and 242±25 picocuries per liter, respectively.

“…For consistency, the 1988/89 data were re-evaluated using the geologic maps. The collection procedure is based on the U.S. EPA procedure (Cecil and Gesell, 1992). The flowrate was reduced to less than 1 gpm, and a pipette was used to slowly collect 10 mL of sample from the hose outlet.…”

“…There are three main isotopes of radon; radon-222 (T ½ =3.82 days), radon-219 (T ½ =3.96 s) and radon-220 (T ½ =0.927 min) for 238 U, 235 U and 232 Th, respectively. Radon-219 and radon-220 are short lived and as such they are not abundant in natural air and water [10]. Radon-222 is a noble gas i.e.…”

Radon concentration in groundwater collected from the eleven Local Government Areas (LGAs) of Ibadan, Nigeria, was analyzed. Annual effective doses due to ingestion and inhalation of radon from the consumption of the water were determined. The arithmetic means (AMs) of radon concentration for the 11 LGAs varied from 2.18 to 76.75 Bq l with a standard deviation of 1.57 and 70.64 Bq l, respectively. The geometric means (GMs) varied from 1.67 to 49.47 Bq l with geometric standard deviation of 2.22 and 3.04, respectively. About 58% of the 84 water samples examined had a higher concentration of radon than the 11.1 Bq l recommended by United States Environmental Protection Agency (USEPA); the AMs of six LGAs and GMs of three LGAs were higher than the recommended value. However the AMs and GMs of all the LGAs with about 93% of the water sampled were lower than the 100 Bq l recommended by the World Health Organization and EURATOM drinking water directive. The concentration of radon varied with the geological formation of the area. The AMs of the annual effective dose due to ingestion of radon in water ranged from 0.036 to 1.261 mSv y, 0.071 to 2.521 mSv y and 0.042 to 1.471 mSv y for adult, child and infant, respectively and the GMs in the range of 0.026 to 0.813, 0.055 to 1.625 and 0.032 to 0.948 mSv y, respectively. The AMs of 10 LGAs and GMs of 7 LGAs were higher than the recommended reference dose level of 0.1 mSv y from the consumption of water for the duration of one year for all the three categories of people. The AMs and GMs of the annual effective dose due to inhalation of radon in drinking water ranged from 0.533 to 18.82 μSv y and 0.411 to 12.13 μSv y, respectively, contributing less to the overall dose.
