radioactive, colorless, odorless, tasteless, noble

I believe only one or two of these adjectives at most appropriately apply to me.

All of them apply to the gas known as Radon (a byproduct of either Uranium or Thorium). Radon is everywhere – inside houses and outside. Average outside levels can be as high as 0.75 pCi/L. (Picocuries per liter. It’s nice that Marie and Pierre Curie have been memorialized forever with a unit of measurement) The national average outside is 0.4. The national average inside homes is 1.3. The average for homes in St. Louis County is 4.0.¬†And the EPA recommends taking action on any home above 4.0.

The home my wife and I are buying currently has radon levels of 4.4. So we will be installing a Radon mitigation device upon moving in.

Here’s an interesting risk chart from the EPA

If 1000 people who never smoked were exposed to radon levels of 4 pCi/L over a lifetime – 7 could get lung cancer. Roughly equivalent to the risk of dying in a car crash. Not exactly a horrific risk level, but on the other hand, reducing the radon level is still a good idea.

The risk is higher for those who have smoked.

Have you checked the radon levels in your home?
