Now let's address the Radon Myths.

Radon Myths:

1) You have to have a basement to have a radon problem.

A) No. 60% to 80% of ALL houses in Spokane/CdA area have elevated radon regardless if the house has a basement, slab or crawl space.

2) Radon Testing and Mitigation are very expensive.

A) No. Radon testing ranges are approximately $75 to $150. Radon mitigation ranges approximately $1200 to $1700 in 85% of local homes. VERY few homes cost more than $2000 for mitigations systems.

3) Only certain areas have a radon problem.

A) Radon is found in high levels in ALL local zip codes. Some areas have higher percentages of homes with elevated levels, or higher radon levels, but radon is found just about everywhere in the Inland Northwest.

4) Vacant homes have higher radon levels.

A) Vacant homes always test LOWER than occupied houses if all radon testing protocols are met. The forces that impact radon are minimized when the house is unoccupied. Heating, exhaust fans, wood stoves/fireplaces and clothes dryers all raise radon levels, but are minimized or not used at all when the house is vacant.

5) If a house has a passive system all you need is a fan installed.

A) This is true for some houses, but not all or even most. If it is a larger home or if the radon levels are above 10 pCi/L the number of homes that can be repaired goes down substantially. It is ART's suggestion that a larger radon fan (Retro style) fan be installed and the home retested to make sure the passive radon system is effective or not. Many homes require a completely new Retro system be installed to reduce the radon levels below 4 pCi/L.

I am sure I will come up with a few more myths so leave me some additional space to add them later. Please use bold and color texts to make the separate parts of this page stand out. The users of this page will know little or nothing about radon, radon testing or radon mitigation.
