Radon remediation involves lowering the concentration of radon in buildings and water supplies. Radon is a radioactive gas that can pose serious health risks. It is also a contributor to the environment. Radon mitigation is necessary to prevent radon from becoming a public health issue. However, radon mitigation requires a large amount of money and time – Go here
What is the most common method of radon mitigation?
Radon is a natural gas produced during the decay of uranium in the Earth’s crust. It rises through soil and bedrock and seeps into buildings through the subfloor and foundation. When levels exceed 4 picocuries per liter, remediation is needed. The World Health Organization recommends that radon levels should be reduced to a level below this level.
Radon mitigation includes sealing holes and cracks. While caulking over cracks can reduce radon levels, it is not effective for large crawl spaces. In these cases, an air-to-air heat exchanger is a good option. This ventilation system is also known as an Energy Recovery Ventilator.
After a radon mitigation system has been installed, it must be maintained. Many mitigation companies offer maintenance services. Homeowners may also do this maintenance themselves. Maintenance can include cleaning the vent stack, sealing cracks, re-painting system parts, and performing radon testing every couple of years.
