Background: Radon, an invisible, odorless, heaviest (nine times heavier than air) and radioactive gas is an aberration (the only gas in the long decay chain of heavy metal elements). It is ubiquitously present in dwellings and in the environment. Humans receive the greatest radiation dose in their homes. That's where they spend most time - typically 70%, more for small children. Recent worldwid...

The recent publications of the combined analyses of residential radon studies in Europe and North America have shown that there is a significant risk of lung cancer at residential radon levels. In order to assess the population risk due to radon, the knowledge of the spatial distribution of indoor radon levels is essential. Here a preliminary radon map for Canada is presented, based on historic...

A method measuring vertical upwards total radon soilgas flow from the ground through building sites before construction is investigated as a predictor for the radon concentration inside a home after construction. The theory for this radon risk evaluation (RRE) is derived and simple analytical and more realistic numerical examples are given. Data obtained from short term radon tests inside homes...

Can a significant number of radon-related lung cancers be averted by mitigating existing single-family houses whose radon is above the action level? Would societal resources be used cost effectively by a comprehensive measurement and mitigation policy using the existing or some other radon action level? Simple questions, complex answers. The risk of lung cancer depends on the radon exposure in ...

Although radon exposure in the home increases the risk of lung cancer, this risk can be managed. However, evidence indicates that testing for radon and subsequent home remediation rates are generally low in many countries. The present perspective outlines some key insights from psychological science that might account for sub-optimal radon protection. Psychological aspects of how the health ris...

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...

Introduction: 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. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...

background: the most popular building materials are soil bricks and different types of stones. radon is released into ambient air from soil and stones due to ubiquitous uranium and radium in them, thus increasing the airborne radon concentration. the radioactivity in soils is related to radioactivity in the rocks from which the soil is formed. in the present investigation, the radon emanated fr...

Attorneys and jurors will have their own ideas of radon health risks before hearing any testimony. For most people, without radiation training, radon is mysterious because they cannot detect the presence of radon with their five senses. For some, radon may not represent a significant danger because people do not see any direct evidence of lung cancer due to radon. For others, radon as a radioac...
