Hi all, can anyone help out, we're stuck for a couple (or one) of geiger counters for the trip to sellafield so we can tell when the maximum dose has been exceeded and it's time to go home ;-)
You'd actually be better off with a film badge, which is a piece of photographic film that gradually turns from black to white as your radiative dose rises. That's what the workers use inside the plants (except apparently in Japan, where all kinds of dodgy shit goes on). One of the major problems with this is it doesn't cover ingested doses, which are much more dangerous in general. But then again neither does a geiger counter. It's stuff like iodine and americium at low radiation levels that get stuck in your body and don't come out, and just build up, that are the main danger, and they're much trickier to measure without a budget. Or if i've totally misread (its 9.55 here give me a break) and you want something for street/beach theatre, film badges suck. Try a dressed-up portable tape player (with a condenser microphone attatched for appearance sake), and play a tape of clicks.
ciao, barry

Barry,
Do u know anywhere we can get one of these things. The CORE one is broken so unless we get one or more of them visiting the beech is out.
I'll ask my house mate who studies physics too.
Slán,
Eoin
