OK, I confess, I'm a serial addict. GM detectors and counters, Ionisation chambers, Gas propotional, Alpha (ZnS) scintillators, Gamma scintillators (NaI(Tl), BGO, Plastic), Beta scintillators (plastic, liquid) Solid state detectors (Alpha, Beta & Gamma), Single and multi channel analysers. Plus isotopes from Am to U totalling several Curies. Includes Cs, but not in a frequency standard, Rb is the best I can manage The radiation detectors make great random event generators ;-) Robert G8RPI.
