Exposure to radon and its decay products in mines is a well recognized risk of lung cancer in miners. A large number of epidemiologic studies from various countries are quite consistent in this respect even it the magnitude of the risk differs according to exposure levels. Indoor radon became a concern in the 1970s and about a dozen studies have been conducted since 1979, mainly of the case-con...

As a part of the safety program at the Limerick Nuclear Power Plant in Pennsylvania, per­ sonnel entering the plant must pass through a radiation monitoring area. In December 1984, the monitoring device detected an abnormally high level of radiation in one construction worker. When an investigation was made to determine how and where this worker was being exposed to excessive radiation, investi...

Estimates of cancer risks following exposure to ionizing radiation traditionally have been based on the experience of populations exposed to substantial (and known) doses delivered over short periods of time. Examples include survivors of the atomic bombings at Hiroshima and Nagasaki, and persons treated with radiation for benign or malignant disease. Continued follow-up of these populations is...

Introduction: Exposure to indoor radon increases the risk of lung cancer. This study examined the level of indoor radon in dwellings of Khorramabad city, by using passive alpha-track detector (CR-39) during winter of 2016. Materials and Methods: In the present study, we detected the concentration of indoor radon in 56 dwellings. A passive sampling instrument (alpha-track detector with CR-39 pol...

A new instrument was developed to measure radon exposure with the use of passive monitors like nuclear track etch detectors. It is based on a device to be switched on and off to permit accurate measurements of timed exposures. The detector arrangement consists of a small cylindrical chamber, a mobile piston inside, a filter holder, a detector holder. The internal sampling volume is variable. Th...

OBJECTIVE To assess the knowledge and perception of parents of high school students about the health effects of environmental hazards in Sakarya province of Turkey. METHOD The cross-section study was conducted in May 2009 in which randomly assigned 362 parents answered a questionnaire inquiring about the sociodemographics and a list of environmental hazards such as tobacco smoking, sunlight e...

Previous research examining radon exposure from granite countertops relied on using a limited number of exposure scenarios. We expanded upon this analysis and determined the probability that installing a granite countertop in a residential home would lead to a meaningful radon exposure by performing a Monte Carlo simulation to obtain a distribution of potential indoor radon concentrations attri...

background: inhalation of radon and its short-lived decay products is one of the ‎most significant sources of exposure to natural radiation. radon is the second cause ‎of lung cancer in the populations. the present study was carried out under the projects of ‎national radon, with the aim of determining the concentration of indoor in the city of qom ‎located in the central semi-arid region of ir...

Based on data from a national residential radon survey performed in 18 cities in Canada in the 1970s, an annual effective dose to the Canadian population due to indoor radon exposure was estimated at 0.71 mSv. An updated estimate of radon exposure in Canada has been made using additional indoor radon data from recent surveys in Ontario and Nova Scotia, and in 28 communities of British Columbia ...
