Radon is a very common air contaminant in homes and some commercial buildings in New England. Radon in the granite under buildings, can be released into well water and ground water and can also seep into buildings through cracks in foundation walls and floors.
The problem with radon gas is two-fold. As it is dissolved in water that is used for showers and laundering of clothes that may be hung to dry it can become airborne, creating an exposure problems. By seeping through the foundation walls and floor, radon gas generally contaminates the lower level of buildings. However it is still possible to find radon throughout a building, especially if a building’s air handling equipment is located on its lower levels.
It is prudent to sample all levels of a building, with emphasis on portions of the building where occupants spend more time, lower, more poorly ventilated spaces and areas where young children play and sleep to determine the worst possible levels that may be present. The samples are collected on a canister that is generally left in place for several days so that a more representative sample can be collected that helps evaluate levels of radon over time and not just as a snapshot.
The Scott Lawson Group, Ltd. can conduct radon testing, and evaluate measured levels, comparing them to the appropriate standards for your type of building. If the result is that exposure levels are too high, our professionals will work with you to develop a mitigation strategy.
