McNulty Plumbing and Radiation Testing use's a Ludlum model 3 Radiation detector to find radiation in a wide variaty of products. We primarily test for radiation in granite countertops but also in any application that may have radiation in it. With 3 scintillaion probes we can detect radiation in the Alpha, Beta and Gamma bands.
If you are shopping for a slab of granite and want it tested before you buy, we can go to your countertop seller and test for radiation without the hassle of having it installed and then finding out it has radiation.
