Review on 🧪 Optimized Geiger Counter Test by United Nuclear by Johnny Pigao

I tested it with Mazur PRM-9000. I placed the card on the radiation monitor. I ran a 1 minute quick average test "three times" and found: µSv/h 95.00 mR/h 8.63 ppm 31,933 No detection in 3 feet of "safe zone". Plastic. Beautifully packaged, you don't have to worry about dust flying off and contaminating the meter, or worse, inhaling it. Handle and store with care as it is radioactive which is why you bought it in the first place.
