Geiger counters are all clicky and such, but that clicking gives you no clue as to where the radiation is coming from, so you can get something between you and it. New Geiger Gas is sprayed (from a handy aerosol can!) into the region suspected to contain harmful rays. Geiger gas contains phosfluorescent
molecules which can be excited to emit visible light by radiation. Now when the technicians scramble to leave the room, Geiger gas can show exactly where those beams are going. Look out! It's like a carcinogenic laser light show! Bring the Pink Floyd and Lead Apron!
Available in Xray and Gamma.

I suspect this won't work, but it is a
pretty idea. The problem is that a gas
will only absorb a minuscule proportion
of the gamma or X-ray photons, and
hence will not be emitting much light
unless the radiation level is huge. |

A Gieger counter also works by
interaction between gas molecules and
radiation, but then (I think - this may
be bollocks) uses avalanche
amplification to give a large electrical
pulse and hence a clear "click". |

Also, Giegers (at least the ones we use)
are very nicely directional - so they
*do* tell you where it's coming from.
(At least for beta - we don't do much
gamma so I'm not sure). |

Even better if the geiger gas is extremely toxic: "Get the hell out! I'm spraying geiger gas!" |
