Yes, you should test for radon
What Is Radon Gas?
Radon is an odorless, colorless, radioactive soil gas that occurs naturally from decaying uranium in the soil and rock. In Central Massachusetts it is not uncommon to find high levels of radon gas in homes. Radon is known to be harmful to humans, particularly over long periods of exposure. It is the second leading cause of lung cancer in the U.S.
What if there are high radon gas levels?
The EPA suggests installing a radon mitigation system when gas levels are 4.0pCi/L or higher. The test results provide this number. For many homes installing a radon mitigation system isn't particularly complicated, however unless you are familiar with radon mitigation you should not assume a certain cost. Your best bet is to obtain a quote from a contractor who specializes in installing radon mitigation systems.
Testing For Radon Gas
The best way to perform a radon test during the course of a real estate transaction is with a continuous monitor. The test equipment is placed at the time of inspection and must remain for a minimum of 48 hours. Results are emailed to you when the equipment is retrieved (typically 3 days).
