A typical radon test kit Fluctuation of ambient air radon concentration over one week, measured in a laboratory. The first step in mitigation is testing. No level of radiation is considered completely safe, but as it cannot be eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced.
Jan. 18—ATHENS — January is National Radon Action month, and each year University of Georgia Cooperative Extension sponsors a poster contest for students across the state to help bring ...
Soil suction, for example, prevents radon from entering your home by drawing the radon from below the home and venting it through a pipe, or pipes, to the air above the home where it is quickly diluted" and the "EPA does not recommend the use of sealing alone to reduce radon because, by itself, sealing has not been shown to lower radon levels ...
Radon can be found in some spring waters and hot springs. [7] The towns of Misasa, Japan, and Bad Kreuznach, Germany boast radium-rich springs which emit radon, as does Radium Springs, New Mexico. Radon exhausts naturally from the ground, particularly in certain regions, especially but not only regions with granitic soils. However, not all ...
Under this modeling, the best policy is obviously to reduce the radon levels of all homes where the radon level is above average, because this leads to a significant decrease of radon exposure on a significant fraction of the population; but this effect is predicted in the 0–200 Bq/m 3 range, where the linear model has its maximum uncertainty ...
A slab-on-grade or basement floor should be poured over a cross-laminated polyethylene vapor barrier over 4 inches (10 cm) of granular fill to prevent wicking of moisture from the ground and radon gas incursion. Inside a steel building, water vapor will condense whenever it comes into contact with a surface that is below the dew point temperature.
