About 20 years ago I kitted out our office with furniture and supplies from a business liquidation auction. Several tape dispensers of that general shape came along with the lot. I guess I had better bring my geiger counter to the office. Probably the wrong vintage, but who knows?

I set off the explosives detectors at LAX on one trip back from Apex Surplus:

My wife ran off laughing while the officers pulled random bomb-looking pieces from my luggage.

I think those detect certain kinds of nitrogen. I wonder what set it off.

monazite isn't radioactive enough to be dangerous unless you're breathing the radon. chemically it's very stable, even without the epoxy encapsulation

Just curious. I bought the geiger counter to verify the authenticity of some fiestaware and discovered that my radium dial alarm clock is hot enough to trigger the alarm.

yeah, radium-dial alarm clocks actually can be dangerous. but i think you can put monazite sand in your food with no ill effects except for tooth wear
