Part of a radon mitigation system including the fan and vent pipe is visible near the gutter downspout. Because high levels of radon have been found in every state of the United States, [18] testing for radon and installing radon mitigation systems has become a specialized industry since the 1980s. Many states have implemented programs that ...
If it is suspected that a private well or drinking water may be affected by radon, the National Radon Program Services Hotline at 1-800-SOS-RADON can be contacted for information regarding state radon office phone numbers. State radon offices can provide additional resources, such as local laboratories that can test water for radon. [109]
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 ...
To achieve these aims, WHO has formed a network of key partner agencies from some 40 Member States. This network is the basis for the WHO International Radon Project which was launched in 2005. Working groups will collect and analyse information on radon risk, radon policies, radon mitigation and prevention as well as risk communication.
Natural radon concentrations in the Earth's atmosphere are so low that radon-rich water in contact with the atmosphere will continually lose radon by volatilization. Hence, ground water has a higher concentration of 222 Rn than surface water , because radon is continuously produced by radioactive decay of 226 Ra present in rocks.
The half-life for radon is 3.8 days, indicating that once the source is removed, the hazard will be greatly reduced within a few weeks. Radon mitigation methods include sealing concrete slab floors, basement foundations, water drainage systems, or by increasing ventilation. [96]
