[ RadSafe ] Radon Testing

[McCulley, Joseph]

We are seeing quite a difference between two methods of testing for
radon.  E-perm electrets read 50% higher than two radon meters running
in parallel.  Any ideas?

   

The two methods we are testing are :  E-perms from Rad Elec, Inc,
Frederick, Maryland, and a Radon Meter from Thomson and Neilsen
Electronics, Ottawa, Canada.

 

Thanks!
