[Imc-makerspace] Fwd: Re: [hackerspaces] Geiger counters

[Chuck Geigner]

Well, just off the top of my head - you may be able to rig a device from a
small CRT - the screen coating/mask would in theory phosphoresce when
bombarded with radioactive particles - if you affixed an array of sensitive
photoresistors in a grid you could at least detect - I'm really not sure if
that would detect all radiation types (alpha, beta, neutron, gamma,
non-ionizing, etc) and how you would even calibrate such a device, but I'll
throw it out there
