Atmospheric radon concentrations were monitored from autumn 2004 to winter 2007 in an abandoned coal mining area of SW Poland that contained various bedrock uranium contents, ranging from 1 to 8 ppm. Gamma spectrometric measurements of eU, eTh and K content in the bedrock were combined with radon-monitoring results at 77 points, obtained via Kodak LR-115 detectors. The average atmospheric radon...

Zinc sulfide coated scintillation cells are the primary method for measuring radon-222 at the U.S. Environmental Protection Agency (EPA), Office of Radiation Programs (ORP), Eastern Environmental Radiation Facility (EERF). These cells are used to measure concentrations of radon in exposure chambers that are used to calibrate or test other devices or instruments. Individual cells are calibrated ...

This paper gives the technical characteristics of the Italian Committee for Research and Development of Nuclear Energy and Alternative Energy (ENEA) radon chamber and the operational procedures developed for testing radon and daughters measuring equipment. Runs were carried out under different experimental conditions defined in terms of radon and daughter concentrations, equilibrium ratio (F-fa...

Radon is a colorless, odorless, naturally occurring gas. It is currently the second leading cause of lung cancer and the number one cause of lung cancer to non-smokers in the United States. DeKalb County offers free screening for radon for residents. However, screening rates vary across the county. This pilot study focused on 14 selected tracts within DeKalb County with relatively low levels of...

Background: Radioactive substances are water chemical contaminants. In this study, the concentration of radon was measured in drinking water supplies of Taft villages (part of Dehshir-Baft fault located in central part of Iran) and also Shirkooh area with granite rocks (containing uranium). Materials and Methods: This cross sectional research was conducted in fall 2013 and winter 2014 on the so...

background: in this study are submitted the radon concentration measurement results of four underground mines: stanterg, artana, hajvali and badovc, which are owned by trepça enterprise, kosovo. the mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. the radiation exposures caused by radon and radon daughters was determined an...

According to the recommendations of the ICRP and the German Commission on Radiological Protection, areas should be identified where increased radon concentrations in buildings occur more frequently than on the country-wide average. Such regions are characterized by an increased radon potential of the building ground. The highest indoor concentrations were measured in old houses of granitic grou...

INTRODUCTION Radon is the second most important cause of lung cancer after smoking. Thus, the determination of indoor radon concentrations in dwellings and workplaces is an important public health concern. The purpose of this research was to measure the concentration of radon gas in residential homes and public places in the city of Shiraz and its relationship with the type and age of the build...

Starting in December, 1996 and continuing through April, 1998, the Tennessee Radon Program, USEPA Region 4 Office, the Southern Regional Radon Training Center, and USEPA Headquarters conducted an investigation of several houses in Livingston, TN in which homeowners had discovered indoor radon concentrations far in excess of their original postmitigation test levels. The investigation team condu...

Although high radon concentrations have been linked to increased risk of lung cancer by both experimental studies and investigations of underground miners, epidemiologic studies of residential radon exposure display inconsistencies. The authors therefore decided to conduct a population-based case-control study in northwest Spain to determine the risk of lung cancer associated with exposure to r...
