indoor radon survey in shiraz-iran using developed passive measurement method

چکیده
background: while in the open air the amount of radon gas is very small and does not pose a health risk, in confined spaces, radon can accumulate to relatively high levels and become a health hazard. exposure to high levels of radon has been associated with an increased risk of lung cancer, depending on the time length of exposure. radon level in dwelling of shiraz with 1,200,000 populations has been sampled and analyzed in this study. our study could be considered the largest radon study in iran both time and area wise. materials and methods: in this study, radon (222rn) concentration in residential dwellings in shiraz-iran was sampled and measured during two consecutive six month periods in 2009- 2010. we used solid state nuclear track detectors (ssntd), cr-39 polycarbonate films. the survey parameters of radon concentrations were floor types, construction materials and dwelling’s age. results: annual average indoor radon concentration for the survey period was 94±52 bq/m3. the calculated mean annual effective doses in basements and different floors were less than the lowest limit recommended action level of 3 msv by icrp. conclusion: high radon concentrations are measured in basements and old dwellings however, due to rapidly changing housing structures and ventilation practices with no intervention, lower levels of radon concentration has been expected in shiraz. iran. j. radiat. res., 2011 9(3): 175-182

متن کاملIndoor Radon Levels in Selected Houses in Isfahan, Central Iran
The highest concentration of radon (222 Rn) and thoron (220 Rn) in indoor environment is a major health hazard for man (1) as a result many researchers (2–4) are interested to estimate indoor radon concentration in many countries. In this study, a survey of radon and its daughters has been done to provide data on the hourly, daily and seasonal average indoor radon in Isfahan city dwellings and ...

Results of the measurement of indoor radon and thoron carried out in and around Srirampura, Bangalore, India using passive detector technique is presented. Measurements were carried out using twin cup radon-thoron dosimeter using small strips of 12 micron thick LR-115 Type II nuclear track detectors. Measurements were carried out in 60 dwellings for a period of one year on a quarterly time inte...
متن کاملRadon in Indoor Spaces
Results: Exposure to indoor radon and its decay products is a major contributor to the radiation exposure of the general population. In Germany, the mean radiation exposure due to radon in living rooms and bedrooms is about 49 Bq/m. It is well documented in the scientific liter ature that indoor radon significantly increases the risk of lung cancer, probably in a linear dose-response relationsh...
