Thanks for waiting. I just got back from Vegas where the people who come up with programs to deal with Radon and Radiation were having a conference and one of the topics was building materials.

I personally spoke to Stanley P. Liebert of CMT Laboratories who denied any direct or indirect correspondence with our Al or the SSA. Mr. Liebert went on to say that the only thing that he is hoping to point out is the fact that 10 out of the 2000 granites emit some radiation. This however, does not directly translate to what we have been reading on the web. That is, if you have a slab that has some traces of radiation it will give off radon with in the next ten generations. Mr. Liebert is also the proud owner of granite as well. He thinks it’s crazy for someone to remove a counter top simply because of one area that may show a reading.

I also had the pleasure of speaking with Erik Listou of Build Responsible, Gary Hodgden of AAIR Professionals, Bill Brodhead of WPB Enterprises Inc, and Shawn Price of Air Chek, Inc. These guys gave me a crash course in radiation and radon while confirming that we had the hottest stone measured to date.

Everyone that I spoke to all had the same conclusion. At this time the radiation from natural stone has no significant bearing on the radon levels in a home. It was also explained and demonstrated that the meters on the market are not the best tools to go hunting for radon coming from natural stone. The areas of a slab can be easily avoided or even removed if deemed necessary.

In the NSRA test kitchen, the numbers before the installation were all very low. All were less than 0.3 pCi/l on the days of testing (about as low as anyone can measure.)

The test kit in the hall was 0.6 pCi/l
The test kit hanging in the door way was 0.8
The test kit hanging from the cabinets was 0.7
And the one we hung 12" over the "hottest" spot was 1.0 pCi/l

This test was done in a way to make sure we got the highest readings possible. We now intend on testing the home as if we were simply testing for radon in the home.
