Radon is one of the most important radioactive gases.Radon emits alpha particles and ultimately,it can cause genetic disorders.There are many reports of carcinogenesis and its harmful effects.One way to get this gas into the body is by eating and drinking.In the meantime,milk is one of the most consuming foods that can be contaminated with radon.In this study, the concentration of radon gas was...

the presence of radon in drinking water causes health risks associated with exposure from both inhalation and ingestion. since the studies show that faults near the water resources have a critical effect on the concentration of radon, kouhbanan active fault zone, to find water resources  with high radon concentration was chosen for the following investigation. water samples were taken from all ...

results in terms of radon and thoron emissions, travertine and plaster were found to be the most appropriate and inappropriate covering for walls, respectively. furthermore, granite and travertine were discovered to be inappropriate materials for flooring, while plastic floor covering was found suitable. natural ventilation performed better for radon, while artificial ventilation worked better ...

background: indoor radon gas (222rn) has been recognized as one of the health hazards for human. air radon comes mainly from basement soil and construction materials. saghand region with rich uranium mines lies 180 km from yazd, so the indoor radon concentration can be high. yazd, with population of about 457000, is the biggest city near saghand, thus, indoor gamma background radiation of yazd ...

background: it is considered that if radon gas is inhaled and ingested, it is the primary health risks for lung and stomach cancers. this paper presents the measurement results of radon activity concentrations both residential tap water and dam water for kastamonu city centre-turkey. materials and methods: the radon activity concentrations of water samples collected from 60 tap waters at four l...

indoor radon and thoron have been measured in the houses ofmoradabad district, uttar pradesh india, by means of solid state nuclear trackdetectors. radon, an invisible radioactive gas, occurs naturally in indooratmospheres and along with thoron is the most important contribution of humanexposure to natural sources. radon exists in soil gas building materials and indooratmosphere to name but a f...

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...

The effects of exposure to radon on workers and members of the public have been examined for many years. Recent advances have been made in evaluating the risk associated with radon exposure and in implementing remediation programmes in dwellings. However, decisions about whether to implement countermeasures to reduce radon exposures may benefit from an enhanced capability to evaluate and unders...
