Radon Mitigation
What is Radon?
The half-life of radon is less than four days so removing or redirecting the source of Radon gas will significantly reduce the hazard within weeks. Radon leves may be reduced by modifying the building's ventilation system. The concentration level or Radon gas increases as the ventilation rate decreases. In a well ventilated place, the radon concentration tends to align with outdoor values from 1 to 100 Bq/m3 but usually about 10 Bq/m3.
Radon levels in indoor air can be lowered in a number of ways, from sub-slab depressurization to increasing the ventilation rate of the building. There are four ways of reducing the amount of radon accumulating in a house:
1. Increasing under the floor ventilaton, or sub-slab depressurization (soil suction).
2. Providing ventilation of the house sufficient to prevent the movement of Radon gases from the basement into the living spaces of the home.
3. Installation of a radon sump system in the basement.
4. Installation of a positive supply ventilation system, or pressurization system.
Companies that perform Radon gas mititagion services can commonly be found in areas prone to high levels of Radon. Test kits are also commonly available.
