Radon Flux Measurements as Predictor for Indoor Radon Concentrations in New Home Residential Structures
نویسنده
چکیده
A method measuring vertical upwards total radon soilgas flow from the ground through building sites before construction is investigated as a predictor for the radon concentration inside a home after construction. The theory for this radon risk evaluation (RRE) is derived and simple analytical and more realistic numerical examples are given. Data obtained from short term radon tests inside homes are compared with numerical model calculations leading to additional insights that are validating empirically the derived connection between radon flux into the building and the radon concentrations. Special circumstances allowed the comparison of over two orders of magnitude of radon concentrations of finished homes with RRE radon concentrations that were obtained following a well defined protocol. Data are presented supporting the usefulness of this RRE-method as part of a radon resistant new home construction program. Conclusions are summarized.

متن کاملPredicted indoor radon concentrations from a Monte Carlo simulation of 1,000,000 granite countertop purchases.
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: 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 popul...

Background: Several epidemiological studies conducted on underground miner’s show that exposure to elevated levels of radioactive radon gas is expected to increase the risk of lung cancer. Relative risk of lung cancer is almost linear with radon exposure. Elevated concentrations of radon are not only reported within mines but also for closed indoor environment of general public houses....

Indoor radon concentrations have been tested in thousands of residential housing units and large buildings during the past six a half years in the State of Florida. Beginning in 1989, testing has been conducted in compliance with the state radon regulations. These regulations mandate that periodic indoor radon testing be conducted in facilities that render services of public nature, and require...
