Final Report of the NC Radon-in-Water Advisory Committee, March 9, 3 Executive Summary Radon (radon) is a naturally occurring radioactive gas and human carcinogen found in groundwater drinking supplies in some parts of North Carolina (NC) at levels that may pose a public health Size: KB. radon a colorless, odorless, radioactive gas that is produced by the decay of uranium in rocks and soil; the gas can seep upward through soil and accumulate in unventilated lower levels of buildngs.
During the last yr, it has erupted at least 28 times. The city of San Miguel (more than , inhabitants) is located 10 km from the summit. An investigation of the concentration of diffuse soil gases—radon, carbon dioxide, and mercury—and soil fluxes of carbon dioxide was done in December –January Field Studies of Radon in Rocks, Soils, and Water focuses on the principal sources of indoor radon and detecting radon through geochemical and hydrological studies of ground water. The book addresses how to measure radon, covers geological field study techniques, .
companies in Minnesota. Most commonly, ground water samples are collected from domestic wells and measured for radon; in some situa tions the radon content of soil gas may be measured as well, but soil gas methods are more time-consuming and subject to considerable fluctuations in the data.

Radon concentration in ground water and soil gas on Wisconsin Indian Reservations, and to determine if there is a relation between radon concentrations in ground water to aquifer, well depth, and soil gas.
Purpose and Scope This report presents results of a study con ducted by the U.S. Geological Survey (USGS), inCited by: 1. Ground water is the principle source of drinking water on Wisconsin Indian Reservations and generally accounts for about 5 percent of the total indoor air radon concentrations found in homes.

Radon gas, moving through the soil, enters buildings through cracks and holes in the foundation. Radon gas easily escapes from well water containing dissolved radon once the water is exposed to air.
This occurs at household taps, washing machines and showers. If there is radon in your well water it will increase your exposure to radon in air. Radon is a naturally occurring radioactive gas in the uranium decay series that has traditionally been called, simply, radon.
The lung cancer risks associated with the inhalation of radon decay products have been well documented by epidemiological studies on populations of uranium miners. The realization that radon is a public health hazard has raised the need for sampling and.
Radon is a chemical element with the symbol Rn and atomic number It is a radioactive, colorless, odorless, tasteless noble occurs naturally in minute quantities as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead and various other short-lived radioactive elements; radon itself is the immediate decay product of ciation: /ˈreɪdɒn/ (RAY-don).

Radon ( Rn) concentrations in 26 ground water wells of two distinct lithologies in the Piedmont of Virginia were measured to assess variation in ground water radon concentrations (GWRC), to evaluate differences in concentrations related to well characteristics, lithology, and spatial distributions, and to assess the feasibility of predicting by: Abstract.

This study demonstrates how the radon (Rn) concentration of soil gas at an active fault is sensitive to cumulative recent seismicity by examining seven active faults in western Japan. The Rn concentration was found to correlate well with the total earthquake energy within a km radius of each fault.
This phenomenon can probably be ascribed to the increase of pore pressure around Cited by: Click here for DISCLAIMER Document starts on next page TITLE: Technical Guidance Manual for Performing Wasteload Allocations, Book II: Streams and Rivers - Part 1: Biochemical Oxygen Demand/Dissolved Oxygen and Nutrients/Eutrophication EPA DOCUMENT NUMBER: EPAB DATE: March ABSTRACT As part of ongoing efforts to keep EPA's technical guidance.
Summary This new book focuses on sampling and analysis, radon and radium in water supply wells, predictive models, geologic and hydrogeologic controls that influence radon occurrence, monitoring radon and other radioactivity from geologic sources and mining impacts on occurrence of.
When the major radon source is the ground, rooms in basements or in contact with the ground have higher radon concentrations than rooms on higher floors. Within rooms the radon concentrations may vary, for example near inlet or outlet ducts, and near points of high inflow of radon from the ground, building materials or radon-rich water.
The soil gas probe was buried in the soil at 30 cm depth for locations SG-2, SG-4 and 50 cm for SG-1 and SG The soil gas sample was drawn through an external pump with one minute sampling time and 15 minute measurement cycles. The results of the active and passive measurements at different depths are shown in Table by: The majority of the water was drained and a sample was collected from the remaining water with a hypodermic needle.
Results A. Supply Concentrations Radon concentrations in the various water supplies sam- pled during this study are shown in table 1. Retained radium generates its daughter radionuclide- gaseous radon During the filters washing, radon is released into the air of the water treatment plant hall.
This will be shown on an example, when the radon concentration in raw ground water is low but it gets into the treated water during the treatment : Eduard Hanslik. Radon, a radioactive gas formed in the soil, can cause lung cancers when inhaled in high concentrations for a long period of time.

While on a statewide scale, it is clear that there are areas of higher and lower ground water radon concentrations, this research suggests that it is difficult to predict lo-cally where high ground water radon concentra-tion may occur.
