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.
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
Radon concentrations can vary daily, and accurate radon exposure estimates require long-term average radon measurements in the spaces where an individual spends a significant amount of time. [ 172 ] Radon levels fluctuate naturally, due to factors like transient weather conditions, so an initial test might not be an accurate assessment of a ...
The relative efficiency of germanium detectors (including other types of detectors) are frequently compared to a standard 3 × 3 sodium iodide detector, representing 100% relative efficiency. Various measurements have shown that cerium bromide (CeBr 3 ) has improved efficiency and resolution compared to sodium iodide, with comparably low ...
The UGA Radon Program has selected its three Georgia radon poster contest winners for the year, with one selected to enter the National Radon Poster Contest ... Homeowners should test for deadly ...
Radon experiments at the Radium Institute in Paris, 1924. Radon is a naturally occurring radioactive noble gas discovered in 1900 by Friedrich Ernst Dorn (1848-1916) and is considered carcinogenic. Radon is increasingly found in areas with high levels of uranium and thorium in the soil. These are mainly areas with high granitic rock deposits.
