So, sure, get a geiger counter. But be careful, because it's addictive! :-O
As long as you are not getting a Tc-99m bone scan just so you can measure yourself (I peaked out at about 25µSv/hr when I measured myself 10 hours after the injection) then you are still ok.


A friend of mine had a Tc-99m scan for something; I got her to put my geiger counter in her pocket and it read over 39K CPM, which is more than any of my pieces. She didn't stay radioactive for long (and wouldn't have fit on my shelf anyway O;-)

Do you have to buy one? can you build one? Heathkit seems to be long out of business, but kits seem to abound for most anything.

FWIW http://www.gqelectronicsllc.com/comersu ... cIndex.asp offers kits that are "99% assembled and tested. You only need to install a geiger tube."
