Bests & Worsts Reviews from Amazon

I have been reading all over the Internet about the amount of radiation that can be found on the west coast. Curiosity got the best of me. I made this purchase to see for myself if this were true. The comments about comparing it to much more expensive radiation detectors helped me decide to make this purchase. I am not an engineer, scientist or one who would have much knowledge about radiation detectors. I use the detector to test air, water, food products and whatever else comes to mind. So far, I haven't seen anything that causes alarm. So, it gives me some peace of mind. I reside in the Portland, Oregon area.
