Friends and colleagues:
I am looking for any data of ventilation rates in residential high-rise
buildings, and possible radon in them, for a literature review and short
paper.
I have two studies now, by Tom Pugh of FL A&M (5 buildings, 5 units) and
Bill Brodhead working in NC (1 building, 5 units). They both show low
ventilation and elevated radon levels in units above the 3rd floor. The
source is likely to be concrete, but I'd like to find more data.
Florida's radon office also has radon data from around 1,000 tests
conducted above the 3rd floor. A third of those tests found radon
levels >4 pCi/L. Some owners have reportedly used ventilation (ERVs) to
lower their radon levels.
Please share with me anything you know of other ventilation or radon
tests in residential high-rise buildings. Also, feel free to re-post
this on any other science list-serves.
Thankx!
