Do any of you have Geiger counters? I came across a comparison test of them on YouTube last night. A woman in Germany tested some "cheap" ($100) units from Amazon against her good one. One of them did about as well as the expensive one. Looking it up on Amazon, it's about half the price she paid. Although I like technology, I wouldn't have much use for one of these. I'd be disappointed that I was always getting low readying, but I'd be terrified if I got high readings "What you don't know can't hurt you."
"...can meet your daily needs for detecting radioactive radiation." Yes, my daily needs.
Try it on bananas. They're supposedly radioactive. Actually, bring it into a supermarket and check the bananas. Have someone accompany you with a clipboard. That'll spook the customers.
Bananas contain naturally occurring radioactive isotopes, particularly potassium-40 (40K), one of several naturally occurring isotopes of potassium.
Actually, they can be useful in evaluating old lenses from, Zeiss, Kodak, and others, some old Glass is radioactive.
I remember somebody somewhere doing the numbers. Something like using those nice pale yellow lenses for 6 hours per day, for 20 years, to equal 1 chest X-Ray. I DID get rid of my glowy watches from the 50's tho,
After WWII there was much war surplus for sale, including optics. I was looking for telescope eyepieces and there were warnings that some were radioactive and should not be used. (I might still have a couple around.)
Jerry, that's just the sort of thing I'd want to do. That is, if I had a Geiger counter. I even have a white lab coat that I'd wear. --Bob

Carried one forever in the demolition business, NORM and irradiated ferrous are big liability issues. One contaminated shipment can take down a mill. TSA surprisingly didn't fuss too bad when taking as a carry on, but trace amounts on shoes could be interesting. You can find a decent one pretty cheap.
