Abstract

Radioactivity in water for human consumption is under closer scrutiny than ever before and many countries adopted guideline values based on total alpha and total beta activity measurements. Although most waters from surface circulation meet these guidelines, it is frequently found that groundwater exceed guideline values. Results of water analyses by alpha spectrometry clarified that the main radionuclides present are from the uranium decay series, such as uranium isotopes, radium ({sup 226}Ra), radon ({sup 222}Rn), and also {sup 210}Pb and {sup 210}Po. Occasionally, groundwater displayed {sup 226}Ra concentrations higher than 1 Bq L{sup -1} and {sup 222}Rn concentrations above 1000 Bq L{sup -1}. Nevertheless, lack of conformity of these waters with guidelines adopted, generally, is not due to anthropogenic inputs.

Risk due to radionuclides in drinking water

Conference Cothern, C; Milvy, P - Preprints of Papers Presented at National Meeting, Division of Water, Air and Waste Chemistry, American Chemical Society; (USA)

Estimates of risk due to radionuclides in drinking water has been evaluated. The primary risk from radionuclides is due to naturally occurring radium, uranium and radon. The average levels of occurrence of these are: {sup 226}Ra 0.3-0.8 pCi/L, {sup 228}Ra 0.4-1 pCi/L, natural uranium 0.3-2 pCi/L, {sup 222}Rn 50-300 pCi/L {sup 210}Pb < 0.11 pCi/L, {sup 210}Po < 0.13 pCi/L, {sup 230}th < 0.04 pCi/L and {sup 232}Th < 0.01 pCi/L. The estimated annual population risks (the number of fatalities per year in the US) are; {sup 226}Ra 3-60 excess cases, {sup 228}Ra 3-60 excess cases, natural uranium 1-10 excessmore »« less
Environmental evaluation of radioactivity levels and associated radiation hazards in groundwater around the WIPP site

Journal Article He, Rong; Liaw, Steven; Zhou, Meng; ... - Ecotoxicology and Environmental Safety

Groundwater may contain radioactive substances which can be dangerous to human health. Concentrations of natural radionuclides polonium (Po), thorium (Th), uranium (U), and radium (Ra) isotopes were measured in groundwater samples collected from different locations in the vicinity of the Waste Isolation Pilot Plant (WIPP) site in Carlsbad, New Mexico. The average values of gross activity concentrations of ²¹⁰Po, ²²⁸Th, ²³⁸U, ²³⁴U, ²²⁶Ra and ²²⁸Ra isotopes were determined to be 1.62 Bq L^-1 in shallow groundwater and 5.88 Bq L^-1 in deep groundwater, respectively. The total radioactivity in deep groundwater was higher than that in shallow groundwater, and most ofmore »« less

Radium, thorium and radioactive lead isotopes in groundwaters: application to the in situ determination of adsorption-desorption rate constants and retardation factors

Journal Article Krishnaswami, S; Graustein, W; Turekian, K; ... - Water Resour. Res.; (United States)

Five groundwater samples taken from different hydrogeologic settings in Connecticut were analyzed for major cation chemistry and the concentration of U and Th decay series nuclides /sup 238/U, /sup 234/Th, /sup 226/Ra, /sup 222/Rn, /sup 210/Pb, /sup 210/Po, /sup 232/Th, /sup 228/Th, and /sup 224/Ra. The concentration of /sup 222/Rn in the waters ranged between 10/sup 3/ and 10/sup 4/ dpm l/sup -1/ and was three to four orders of magnitude greater than that of the short-lived alpha daughters /sup 224/Ra, /sup 228/Ra, and /sup 234/Th, even though the rates of supply of these four nuclides to solution are expectedmore »« less

Natural radioelement solution by circulating ground waters in the Stripa granite

Journal Article Andrews, J; Ford, D; Hussain, N; ... - Geochimica et Cosmochimica Acta; (USA)

Natural radioelement concentrations in ground waters from the fracture flow regime in the Stripa granite were monitored during the period 1977-1986. Uranium concentrations from depths of 80 m or less and in mine waters from above the hydraulic sink produced by the deepest mining level (410 m), range from 10 to 90 ppb. {sup 234}U/{sup 238}U activity ratios are characteristic of chemical leaching processes at the shallower depths whilst at about 350 m ground waters occur which have an additional component of {sup 234}U by alpha-recoil processes. At greater depths, U concentrations are indicative of the changed redox conditions andmore »« less

Indoor Radon Measurements from Residential Buildings with Basements in a Community with Potential LLRW Contamination - 19566

Conference Stager, Ron; Chambers, Douglas; Kirkaldy, Jennifer

The Port Hope Area Initiative (PHAI) represents the Government of Canada's commitment to the cleanup and safe, local, long-term management of historic low-level radioactive waste (LLRW) in two Southern Ontario municipalities-Port Hope and Clarington. The PHAI (see reference for internet address) is based on community-recommended solutions for the cleanup and safe long-term management of approximately 1.7 million cubic meters of LLRW. It is currently one of Canada's largest environmental remediation projects at a cost of over one billion dollars. Canadian Nuclear Laboratories (CNL) is implementing the PHAI on behalf of Atomic Energy of Canada Limited, a Federal Crown Corporation. Anmore »« less
