DOI: 10.1144/SP451.2
EISBN: 9781786203328
... Abstract The majority of radon measurements in the built environment are made over sub-year periods and are then generally seasonally corrected (i.e. scaled by an appropriate seasonal correction factor (SCF)) to estimate the annual average radon concentration. SCFs are statistically derived...

... Abstract Understanding the behaviour of fluids in hydrothermal systems is a key factor in volcano monitoring. Measuring gas emissions in volcanic areas is strategic for detecting and interpreting precursory signals of variations in volcanic activity. The role of radon as a potential precursor...

... Abstract Radon is generally regarded as a naturally occurring radiological hazard but we report here measurements of significant, hazardous radon concentrations that arise from man-made sources: for example, radium-dial watches. This study is an examination and assessment of health risks from...

... was greatly improved thanks to the outstanding detailed work of two reviewers. This is IPGP contribution No. 3731. The radon-222 exhalation from any porous medium is proportional to the activity concentration of radium-226, C Ra , and to the probability of a radium atom emitting its radioactive product...

... Radon is a colourless and odourless naturally occurring radioactive noble gas. Radon has a number of isotopes but only two (i.e. 222 Rn (herein ‘radon’) and 220 Rn (herein ‘thoron’)) are thought to pose any threat to human health ( Cliff & Gillmore 2001 ). Of these, 222 Rn (plus its progeny...

...) , more detailed and some additional regulations are stipulated. Radioactivity in drinking water in Austria is regulated as parametric values for tritium, radon and the indicative dose (ID). These parametric values are detailed in Table 1 . The indicative dose is the sum of the dose contributions...

.... These studies have focused mostly on naturally occurring asbestos, radon, and various metals, such as mercury and cadmium. The mineral-hazard maps and companion reports produced from these studies are typically at statewide and regional scales. They are designed for use by nongeoscientists and geoscientists...

..., the gamma-ray flux from the uranium decay series was highest in the spring when the ground was water-saturated and even covered with snow. These results are explained through the build-up of radon and its associated gamma-ray-emitting decay products in the clay soil of the calibration range with increasing...
