Jim Katen Posted November 3, 2010 Report Share Posted November 3, 2010 So, WA guys, is there some kind of requirement for new homes to be pre-plumbed for radon reduction systems up there? I've just seen my second house in the 'Couve that's pre-plumbed for radon. Built in '07. ??? - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Richard Moore Posted November 3, 2010 Report Share Posted November 3, 2010 What's Radon? Seriously though, not as far as I'm aware of for this area (always willing to be corrected). And, I can't speak for the red zones in the lower left or upper right corners of the state. Click to Enlarge 25.89 KB Wouldn't it be more likely to be local/county requirements?

By the way, those maps are nearly worthless. I once asked about the number of cases that they were based on, and it ain't anywhere near a statistically valid sample. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Richard Moore Posted November 3, 2010 Report Share Posted November 3, 2010 Hi again... So I dug a little and found that it is in fact covered by the State's VIAQ codes for high risk areas/counties. You can see the requirements here... http://www.spokanecounty.org/loaddoc.aspx?docid=2265 Good thing I don't travel too far, eh? Look at the difference in the Radon Pie Charts for Spokane and King County. http://county-radon.info/WA/Spokane.html http://county-radon.info/WA/King.html I've always believed we have low levels here because our "soil" is mostly glacial till rather than bedrock.

Rob Amaral Posted November 3, 2010 Report Share Posted November 3, 2010 The maps are I believe based on overfly gamma surveys.. (DOE was looking for uranium, the parent of radon). They criss-crossed the US and created those maps.. They are actually pretty good.. considering how they were done.. They are not based on 'radon tests'.

msteger Posted November 27, 2010 Report Share Posted November 27, 2010 I don't even show those maps to people because all they have to see is that they are in a yellow county and then they'll assume "we have no radon here". "Luckily", being in Lancaster County, PA where our county avg is about 17.9 pCi/L (and every county around here is near as high on avg), it's not tough convincing clients get a radon test performed. I tell my clients that every home is different.. you can't really go by a map or EPA stats. Test your home. That's the only way to know.
