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...

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...

background: radon concentration was measured in the soil and indoor of amman and al- rusaifa cities in jordan during summer season. materials and methods: the measurement was performed using time-integrated passive radon dosimeters, containing a solid state nuclear track plastic detector, commercially known as cr-39. results: radon concentration levels in the soil ranged from 2.8 ± 1.2 to 6.9 ±...

the paper discusses the results of 30 years of radon indoor entry research. while some progress has been made, many discrepancies between current theories and experimental data still remain. misconceptions of radon transport mechanisms in homes are analyzed. the role of us environmental protection agency in radon indoor entry research is examined and the agency's policies are criticized. t...

Radiation from natural sources is one of causes of the environmental diseases. Radon is the leading environmental cause of lung cancer next to smoking. To investigate the relationship between indoor radon concentrations and lung cancer, researchers must be able to estimate an individual's cumulative level of indoor radon exposure and to do so, one must first be able to assess indoor radon conce...

The relative potential for elevated residential indoor radon has been mapped for the City of Fort Collins, Colorado. Using published geologic maps and soil permeability information, the study area was divided into geologic and soil permeability (geoperm) units. Evaluation of the data showed a relationship between residential basement indoor radon concentrations and geopenn units. Mean indoor ra...
