Apparently I have a radioactive rock

Cool. Interesting stuff. The inflation in the bag is what was concerning me. I opened it the other week, letting the gas out. Then retied it. It's swollen a bit since then. no one from Bristol uni has emailed back yet.

I think it's fresh lava...I googled rock emitting gas and got this....

Buy some film - or one of those disposable cameras.

Leave rock sat on top of (unopened!) film for a day.

Develop film.

If it's black, you have a radioactive rock.

Surely "if it's white"? Or do you mean the negative film itself, not the photos?

I mean the film, as I said.

You aren't going to get any prints, because the printer - whether machine or human is going to look and either say "unexposed film" (all clear) or "kind of blotchy" (eek!) or "all black" (EEEEKK!).

You could build a KFM meter which is the cheapest radiation detector about. It only uses stuff you can find about the house and doesnt need any calibration or suchlike. You'd have to let it run for a period of time away from the rock to establish background levels before you actually tried it on the rock. Note that it is a dosimeter not a counter, so it registers radiation over time.

theres instructions here: http://www.oism.org/nwss/s73p938.htm

you can also buy them as a kit or ready to use. They arent that sensitive though, so unless the rock was pretty hot you might not pick anything up.

I really wouldnt worry about it. Just put it outside.

Already posted the plans for that and no bugger commented.
