OBJECTIVES To evaluate the relation between exposure to ground radon levels and leukaemia among children using existing population and disease registers. DESIGN Ecological correlation study. SETTING The county of Ostergötland in Sweden. METHODS Every child born in the county between 1979 and 1992 was mapped to the property centroid coordinates by linking addresses in the population and pr...

The Ohio Radon Information System (ORIS) internet site at http://www.uioledo.edu/-aprs/oris/ is one of the most comprehensive sites on indoor radon available on the World Wide Web. It was developed by the authors under a research grart from the Ohio Department of Health and U.S. Environmental Protection Agency. It is estimated that from 700 to 1300 people die annually in Ohio from radoninduced ...

Background: Many different methods are applied for radon mapping depending on the purpose of map and data that available. In addition, definitions priority areas (RPA) in EU Member States, as requested new European EURATOM BSS (1), diverse.
 Objective: 1) Comparison geogenic indoor radon, 2) possible transferability a method developed one region to other regions 3) evaluation impact deline...

Indoor and outdoor (atmospheric) radon activity concentrations need to be measured as accurate possible for radiation protection climate applications. Particularly below 100 Bq m −3, useful the retrieval of prone areas atmospheric studies, still a robust metrological chain ensure their quality. Ones most common used commercial continuous monitors were compared here under slightly different envi...

Vulsini Volcanic district in Northern Latium (Central Italy) is characterized by high natural radiation background resulting from the high concentrations of uranium, thorium and potassium in the volcanic products. In order to estimate the radon radiation risk, a series of soil gas radon measurements were carried out in Bolsena, the principal urban settlement in this area NE of Rome. Soil gas ra...

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...

Abstract This paper reports a review on the relationship between seismic activity and emissions of CO 2 radon. Direct, indirect sampling methods are mainly employed to measure flux concentration in areas. The accumulation chamber technique is mostly used literature. Radon gas emission areas can be considered as short-term pre-seismic precursor. study measurement radon prior earthquakes performe...

Results of a soil radon survey accomplished by 2 different methods during 2 different periods in the area of Tlamacas Mountain are presented. The first study, carried out from 15-APR-2010 to 09-MAY-2010 in 30 measurement sites by means of CR39 solid state nuclear detectors, shows 2 active zones with intensive radon emanation with a characteristic dimension of about 300 meters located in the nor...
