Michael Petruccelli asks; What are some things you should know if, it been a while since you last bought or sold a home? (10)

Michael Petruccelli says;  What is radon testing?

Radon is a tasteless, odorless, and invisible natural radioactive gas formed by decaying uranium in the earth’s soil. Radon moves up through the ground and enters a building by seeping through cracks, etc. and then becomes trapped in the home. Research has linked radon gas with lung cancer, so the Surgeon General and EPA recommend homes be tested to make sure radon levels are with in a safe range.
