I'm still working on getting a fireman to come out to the school to demonstrate a radioactive detector. No luck so far. This is for a project on Marie Curie.
Any other suggestions would be greatly appreciated.

I assume you have talked to the chief of the RADHAZ team.
Marie Curie discovered Radioactivity, that is the essence of her greatness. I guess you could make a poster on that failing the fun demo.

Do really you need a fireman to demonstrate one? Most smoke detectors contain a radioactive Americium-241 source. The only problem might be coming up with a smoke source to test it. Cigarettes are banned from public buildings now. You might consider blowing talcum power at it.
There is a good article about how they work at
What do you want the fireman to demonstrate: the detection of smoke or the radioactivity of the Americium source?
