[GBlist] RE: flyash concrete

["Tom Lent" <tlent@igc.org>]

Provocative statement... What do you mean when you say any building
product must be tested for radon? Do you suggest a protocol? Who should
do it and how often? Should this just be done every ten years for a
product? On every batch of concrete? Somewhere in between?

Any building product, no matter what its raw material, must be tested
for radon. You can not make a general statement about any material that
it does or does not contain significant radon without testing. Even a
straw-bale house could have high radon if the straw were grown so as to
= have a high uptake of radon.
