Historically the EPA has supplied some of the State Radon Programs with printed copies, but the states weren't able to have enough to supply radon professionals with them. There are a couple places that will charge for printed copies to cover the production and shipping costs. RadonAway and AARST are places that have had them in the past.

I always got them from the AARST office (which has always been within a few miles of home.)

Thanks all. I was looking for the printed booklet and have found them.
