What's all the fuss about RADON?
Really, is radon a legitimate concern in our part of the county? I thought we were out of the "hot" zone. You know, the Midwest. Are some unscrupulous sorts playing on our ignorance and fear to drum up business doing unnecessary testing and mitigation of our homes?
It's not the intention of this article to prove that radon is present in Oregon. Hundreds, if not thousands, of measurements taken in the area prove that it is present. But it is also true that Oregon does have lower levels on average than the rest of the nation. About 4 percent* of Oregon homes verses 8 percent nationally have been found to have elevated levels. The purpose of this article is to put it in perspective. In other words, so what? What is radon's significance. Does it really matter?
Radon levels vary by zip code and within zip codes. Two homes, side by side, may have very different readings, one elevated and one low. And what is considered an elevated reading? Any reading at or above the well-established and accepted threshold of 4 pico-Curie/Liter (pCi/L.)** The Environmental Protection Agency advises that if a home has elevated readings, steps should be taken to reduce those levels. Why? To summarize their words: Radon is the second leading cause of lung cancer, responsible for an estimated 21,000 deaths per year in the USA.
So am I saying that if your home has elevated levels of radon you're more likely to get lung cancer? No, the EPA is saying that. But they also say that time is a factor. Someone has compared the risk of getting lung cancer from radon to throwing darts at a bull's eye. The odds of hitting it with only one throw are pretty low. But if you had all day, or all week, or a whole year, or half a lifetime, given enough time, the odds of hitting it increase to nearly 100 percent. Even at levels lower than 4pCi/L.
So it's a matter of time of exposure. Although the radon level may be low, the longer the exposure to it, the greater the chance that lung damage from radon will lead to lung cancer. Sounds a bit like exposure to cigarette smoke, doesn't it? Even second-hand smoke.
I guess it boils down to this. There are things in life we can control and things we can't. If some of the things that cause lung cancer, like cigarette smoke and radon, can be controlled, why wouldn't we?
* Although in the Portland area one study found 16 per cent of homes have elevated levels.
* * 1 Curie = the amount of radioactivity released by 1 gram of radium. A pico-Curie = one-trillionth of a Curie (named after Madame Curie).
