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 ...
In many cases, mitigators can use PVC piping and specialized radon suction fans to exhaust sub-slab, or sub-membrane radon and other soil gases to the outside atmosphere. Most of these solutions for radon mitigation require maintenance, and it is important to continually replace any fans or filters as needed to continue proper functioning. [109]
Maps of average radon levels in houses are available, to assist in planning mitigation measures. [8] While high uranium in the soil/rock under a house does not always lead to a high radon level in air, a positive correlation between the uranium content of the soil and the radon level in air can be seen.
An estimated 42% of all buildings in Kentucky — and more than 65% in some areas — have elevated radon levels, compared with 7% nationally, according to the Kentucky Association of Radon ...
Radon concentration can differ widely from place to place. In the open air, it ranges from 1 to 100 Bq/m 3, even less (0.1 Bq/m 3) above the ocean. In caves or ventilated mines, or poorly ventilated houses, its concentration climbs to 20–2,000 Bq/m 3. [79] Radon concentration can be much higher in mining contexts.
