متن کاملExperimental Design for Soil Gas Radon Monitoring
Radon, the radioactive daughter product of the decay of has been the subject of scientific inquiry since its discovery in 1900 by DORN. 1 Because it is ubiquitous radium, initial in the environment, it has been studied as a means to better understand such diverse processes as earthquake precursors2 ' 3 atmospheric circulation patterns 4 , eruptive and non-eruptive volcanic processes5 , and grou...
متن کاملSoil gas radon assessment and development of a radon risk map in Bolsena, Central Italy
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...
متن کاملComparison of Methods to Determine Radon in Soil Gas
Various methods to determine 222Rn concentration in soil gas were tested at two sites with different soil types in a depth of 1 m. They include instantaneous (spot), continuous (real time) and timeaveraging procedures with advective ('active' procedures) or diffusive ('passive' procedures) gas transport from soil to detector: a) active grab-sampling of soil gas from different thin soil gas prob...
متن کاملSoil gas measurements below foundation depth improve indoor radon prediction.
A soil gas measurement method developed earlier, [Nucl Tracks Radiat Meas, 22(1-4) (1993) 468] was applied to boreholes drilled to below foundation depth. Radon concentration and permeability were measured at 50-cm intervals. In radon prone areas, permeability showed an increase with depth over several orders of magnitude, indicating a low permeability top layer with a thickness of 0.5 m and mo...
