Review of F.A.Q. in
EPA's Home Buyer's and Seller's Guide to Radon
The F.A.Q. format is perfect for reviewing the Questions and Answers section
EPA recommends that you take action to reduce your home's
indoor Radon levels if your Radon test result is 4 pCi/L or higher. A radon
meter or radon test will measure the radon levels according to this pCi/L
The EPA recommends that it is better to correct a Radon problem
before placing your home on the market; because, then you have more time to
address the problem..
The EPA recommends that if elevated levels are found during
the real estate transaction, the buyer and seller should discuss the timing

Sealing cracks and other openings in the foundation is usually
the first step, yet EPA does not recommend the use of sealing alone to limit
Radon entry. That's because they say sealing alone has not been shown to lower
Radon levels significantly or consistently. In addition, a system with a vent
pipe(s) and fan(s) can be installed to expel and therefore reduce the Radon..
That's the system with a vent pipe(s) and fan(s) that can
be installed to expel and therefore reduce the Radon. Similar systems can
also be installed in homes with crawl spaces, as well as under the slab. Sub-slab
depressurization prevents Radon gas from entering the home from below the
concrete floor and from outside the foundation, by expelling it to the outside.
Radon mitigation contractors may use other methods that may also work in your
home. The right system depends on the design of your home and other factors..
California Department of Public Health found that in the
Truckee area, roughly a quarter of homes tested at or above the EPA action
level of 4.0 pCi/L. In North Lake Tahoe, about 1 in 5 homes tested at or above
that value. And finally, more than half of the homes in South Lake Tahoe tested
