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.
In the US, radon test kits are available to the public at retail stores, such as hardware stores, for home use, and testing is available through licensed professionals, who are often home inspectors. Efforts to reduce indoor radon levels are called radon mitigation. In the US, the EPA recommends all houses be tested for radon.
Radon concentrations found in natural environments are much too low to be detected by chemical means: for example, a 1000 Bq/m 3 (relatively high) concentration corresponds to 0.17 picogram per cubic meter. The average concentration of radon in the atmosphere is about 6 × 10 −20 atoms of radon for each molecule in the air, or about 150 atoms ...
Radon is measured in picocuries per liter of air (pCi/L) or becquerel per cubic meter (Bq m-3). Both are measurements of radioactivity. The World Health Organization (WHO) sets the ideal indoor radon levels at 100 Bq/m-3. [97] In the United States, it is recommend to fix homes with radon levels at or above 4 pCi/L.
Residues from the oil and gas industry often contain radium and its daughters. The sulfate scale from an oil well can be very radium rich. The water inside an oil field is often very rich in strontium, barium and radium, while seawater is very rich in sulfate: so if water from an oil well is discharged into the sea or mixed with seawater, the radium is likely to be brought out of solution by ...
We’d just gotten home from work, had a million things going on, ate dinner, and were finally looking forward to some quiet time. Then, our dogs started whining and barking at us, giving us that ...
