Introduction: Internal exposure to radon gas progeny can lead to serious biologic damages to the lung tissue. The aim of this study was to evaluate the absorbed dose by lung tissue due to the exposure from short-lived radioactive products of radon (222Rn) decay using Monte Carlo simulation. Material and Methods: A lung equivalent p...

introduction radon is a colorless and tasteless gas which exists in most soils. it is a substance that poses a potential risk for lung cancer in case a person is exposed to high levels over long periods of time. the environmental protection agency (epa) estimates that 90% of lung cancers per year are caused by radon. the aim of this paper is to estimate the absorbed doses of 222rn by mcnpx simu...

Radon is a naturally occurring radioactive gas produced from the decay of uranium in the earth’s crust. Its presence is ubiquitous at the earth’s surface even though its production, and consequently its concentration, are not uniform. Radon can infiltrate into buildings basically through cracks and other routes of entry in the basement. Also, since it is heavier than air, it tends to concentrat...

indoor radon concentration (irc) is among the emerging environmental and health issues in republic of korea. due to lack of epidemiological studies and insufficient public awareness about radon, effective parameter ranking system is required to establish protocols for future field sampling and settlement construction. this research propose the irc parameter ranking system based on field measure...

background: the natural radioactivity level and the radon concentration of soil were measured at four important geothermal area located in dikili geothermal region, turkey. materials and methods: the natural radionuclide content of soil samples were measured by nai(tl) gamma spectrometer system and the soil radon concentration were determined using kodak-pethe lr-115 type ii solid state nuclear...

Lung cancer was the most commonly diagnosed cancer as well as the leading cause of cancer death globally. It accounts for 13% (1.6 million) of the total cancer cases and 18% (1.4 million) of the cancer deaths in 2008 (Jemal et al., 2011). Although the majority of lung cancer cases can be attributed to active cigarette smoking, radon exposure was also an important contributor to the total burden...

Radon gas in the home is a major source of public radiation exposure and an established cause of lung cancer. A range of techniques are available to reduce high indoor radon concentrations in homes. Information on some 2,700 radon remediation projects has been analysed with the aim of identifying the factors that influence the performance of various remediation methods, including the specific r...

Radon and its decay products are the main source of ionizing radiation in non-industrial buildings. They are responsible for about half of the radiation dose people in Poland are exposed to [1]. Radon is a naturally occurring radioactive gas that originates from the decay of radium (226Ra) in the primordial uranium (238U) decay series. Radon concentrations in buildings are usually higher than o...
