Re: Alpha Track Radon Detectors

[FIELDRW@aol.com]

I know REM used to sell them.  I believe Dr. Naomi Harley developed a detector
which she has sold to a company that has the potential to measure thoron.
Someone else may know the name of the company?

  Also, Dr. Daniel Steck at St. John's University has an ATD that measures
thoron.  His email is dsteck@csbsju.edu.

Good Luck.
