Radon is a naturally occurring radioactive gas that is colorless, odorless, and tasteless. It is considered to be the leading cause in lung cancer deaths in non-smokers and the second cause amongst those who smoke which is why it is referred to as the silent killer. It is formed by the decay of uranium and thorium, which are present in most rocks and soils. The U.S. Environmental Protection Agency (EPA) recommends that homes be tested for radon, and that homeowners take steps to mitigate radon levels if they are found to be high.
The Environmental Protection Agency (EPA) recommends that homes be remediated if the radon level exceeds 4 picocuries per liter (pCi/L) of air. However, the World Health Organization (WHO) recommends a lower action level of 2.7 pCi/L. It's important to note that while the recommended action levels vary, there is no safe level of radon exposure. Radon is a known carcinogen, and the risk of lung cancer increases with higher levels of exposure. Even radon levels below the recommended action level can pose a risk over time.
Reducing radon levels in buildings can help to reduce the risk of lung cancer and other health problems associated with radon exposure. The process of radon remediation involves identifying the source of the radon, typically through testing, and then taking steps to reduce the amount of radon in the air.
Radon remediation can include sealing cracks and openings in the foundation, improving ventilation, and installing a radon mitigation system, such as a fan or other equipment that can help to vent the radon gas from the building. The specific approach used for radon remediation will depend on the nature and severity of the radon problem, as well as the characteristics of the building.
Overall, radon remediation is an important step to protect the health and well-being of those who live and work in buildings that may be affected by radon.
