Radon, a radioactive, odorless gas emitted from the soil  and it is a concern for homeowners or those looking to buy a house.

A home inspection should always include a radon test. Radon can seep into homes and buildings through cracks. Inhaling it has been linked to lung cancer, killing an alarming 21,000 people a year.

If a home test shows high levels of radon, it’s not the end of the world. Radon-related deaths are connected with exposure over the course of a lifetime, and Consumer Reports says that exposure can be dealt with.

If radon registers between 2 and 4 picocuries per liter, a home repair is in order. For about $1,200, homeowners can install a pipe that vents radon from the soil out through the roof.
