After reading about a product in Jerry's stories, I decided to do some more research into it. It is the "Keychain Radiation Detector" that everyone seems to have in his stories. I found prices from around $100 to $200 and I was wondering if anyone here has any real-world experience with either of them? Now, I am not expecting a nuke to pop this town, but, that doesn't mean that I wouldn't be going through areas where natural radiation occurs (uranium mines, etc). The two products that I found are at: RADDETECT RADIATION DETECTOR at Survive4Less NukAlert™ Radiation Detector, Meter, Monitor and Alarm There might be other products out there as well that I haven't found (yet) - so I am open to alternative suggestions. Which would be the "best" for the "best price". I wouldn't wanna spend $200 on a single one if I can get two keychain-units for that same $200 that has the same level of accuracy. I hope you understand, money being what it is, I wanna get the best value for the best product, but, I don't mind paying more if it is the better choice.
