Radon Videos

Radon Video from Spruce

I get a lot of requests to post other people’s content on my blog. As MY blog, I usually just post MY stuff. I’m making an exception today because I came across a video about radon that was very well done. The graphics are great and it does a good job of explaining radon and radon mitigation. The video takes some artistic liberties, but all in all, a good intro video to radon.


Do you know your state’s radon regulations?

Some indoor air quality contaminants are regulated on a federal level, others on a state level, some a combination of the two, and others have no regulations whatsoever.  This poses a tricky problem for anyone working in the field of indoor air quality.

Radon is a great example of a contaminant regulated at the state level.  For professionals working in multiple states, it can be maddening to wade through the various requirements and regulations.  I’ve always been on the lookout for a comprehensive list of state radon laws.  I even toyed with building one myself, but that would be a month worth of work.

You can imagine my elation when I came across a fully compiled list of all the state regulations!  Credit goes to Betsy Janes of the Northern Kentucky Radon Coalition who posted the list to (September’s IAQ Website of the Month).

Check out this law in my state of Illinois:

It is a misdemeanor to misrepresent the capabilities of a device for detecting and measuring radon or radon progeny.

You can attempt to sell a Senate seat in Illinois and not get convicted, but darned if you misrepresent the capabilities of a continuous radon monitor in our great state!

To see the full list of radon laws, visit this page on the radon leaders website:  The list was compiled in August of 2009 so it may not be 100% up to date.  Always check with your state’s radon office for the latest regulations.

If you know of any new radon laws, please leave a comment below!


Radon on the Map

Radon is a radioactive soil gas that is the leading cause of lung cancer in non-smokers according to the EPA.  The US Surgeon General issued a Health Advisory a few years ago to warn the public about radon’s health risks.  To read more about the health effects of radon, you can visit the EPA’s website.  In this blog post I want to discuss how radon levels vary geographically.

Radon is a decay product of radium (which, in turn, is a decay product of uranium).  Because uranium is found in the soil at different levels throughout the world, radon concentrations vary quite widely.  A few maps are publicly available that display the average radon levels throughout the US.  The problem with these maps is that the average concentrations are for an entire county or region.  Your home, school or office may be in a neighborhood with levels significantly higher or lower than the region’s average.

Nevertheless, I think that radon maps can be a useful tool to understand the geographic trends.  Here are the three radon maps in the US that I like to reference:
