Two calibrated Radon Scout continuous radon monitors were installed in the basement of a typical single family home in Frederick, MD, USA, in accordance with the USEPA deployment protocols. These units were set to collect and average radon concentrations over three hour intervals. In addition to logging the average radon concentrations, the basement temperature, humidity, and barometric pressur...

There is a growing recognition in the United States and Europe that health care is driven to a significant extent by an emphasis on consumer choice and demand. As consumers, people regularly choose their own solutions for health promotion and maintenance, solutions which may or may not be sanctioned by mainstream medicine. Radioactive radon therapy exemplifies a non-sanctioned treatment eagerly...

Radioactive radon therapy is a little-known pain relief modality in the US, although it is an accepted therapeutic choice in many parts of Europe and Japan. Radon therapy has been extensively studied by European and Japanese physicians and scientists but information about the specific therapeutic applications of radon in the US is limited to anecdotal and ethnographic data. The purpose of this ...

The potential risk of indoor radon for the public in Switzerland has been comprehensively investigated by the Federal Office of Public Health since 1994. Numerous radon measurements have been carried out to da te and they show that several regions in Switzerland are affected by high levels of radon exposure. In a pilot study different methods of indoor radon prevention and remediation have been...

The biokinetics of radon in the body has previously been studied with the assumption that its absorption through the skin is negligibly small. This assumption would be acceptable except in specific situations, such as bathing in a radon hot spring where the radon concentration in thermal water is far higher than that in air. The present study focused on such a situation in order to better under...

Background and purpose: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Alpha particle emissions as a radon gas decay product can increase the incidence of lung cancer in human. Every person spends ...

B Amanat MR Kardan, R Faghihi SM Hosseini Pooya,

Background: Radon and its daughters are amongst the most important sources of natural exposure in the world. Soil is one of the significant sources of radon/thoron due to both radium and thorium so that the emanated thoron from it may cause increased uncertainties in radon measurements. Recently, a diffusion chamber has been designed and optimized for passive discriminative measurements of rado...

Background: Radon is one of the most important radioactive elements which is released by natural decay of available uranium and radium in the ground. The presence of radon gas is common, wherever those faults are located there. Radon concentration of various drinking water resources of Bam villages; located near Bam fault; was measured. Materials and Methods: This cross-sectional study was cond...

For underground particle physics experiments, noble gas radon from U-chain decay series could be a source of serious background events. We have developed a high sensitivity detector for radon using electrostatic collection and PIN photodiode. Recently, we have developed a new type of radon detector. We report basic performance of the new 80L radon detector.
