Radon gas is a colorless, odorless, tasteless radioactive gas that's formed during the natural breakdown of uranium in soil, rock, and water. Radon exits the ground and can seep into your building through cracks and holes in the foundation and can also contaminate the water.
Because high levels of radon have been found in every state of the United States, testing for radon and installing radon mitigation systems has become a specialized industry since the 1980s.
Facts About Radon Gas
- There are no average radon levels for a specific city, state, or region.
- Buildings without subterranean levels are as much at risk of radon contamination as buildings with subterranean levels.
- It doesn't matter if a neighboring property radon test was low or high, results for your building are independent and may be completely different.
The first step in mitigation is testing to see if the indoor-air and/or domestic water radon concentrations should be reduced.
Governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced while recognizing that radon cannot be eliminated. The World Health Organization's International Radon Project has recommended an action level of 2.7 pCi/l for radon in the air.
The Environmental Protection Agency recommendation is to not test for radon in water unless a radon in air test is above the action level.
Testing large areas or buildings can be a complicated and lengthy process, so should only be performed by a Licensed Mitigation Professional.
There are varying methods of treatment, but once again due to the speciality of processes and safe handling practices associated with Radon Contamination, services should only be performed by a Licensed Mitigation Professional.
A mitigation system draws radon from beneath the building and vents it away from the house through pipes.
- respiratory issues
- nasal and sinus congestion
- eye irritation
- sore throat.
- hacking cough
- chronic fatigue
- central nervous system issues
- aches and pains
Sealing alone doesn't usually lower radon levels, but it can limit the flow of radon into the building and reduce the loss of air that's been heated or cooled.
This method uses a fan to create pressure differences that help keep radon from entering the building.
Installed to increase ventilation, HRV uses the heated or cooled air being exhausted to warm or cool the incoming air. This type of system is most effective when used to ventilate only the basement or subterranean levels of the property. Heating and cooling costs will likely rise when an HRV system is in place.
