I think this is a good rule of thumb you can use to judge how dangerous any stolen radioactive material might be: If you can find it listed for sale at Amazon, it's probably not something you have to worry about.

Good point, but the name of the item wasn't listed anywhere, and I can't read it on the unit itself in the picture.

Like I said in other posts - it's a matter of security. This is a low-level source, but higher power sources are out there as well, and they're not any better secured than this thing is.
