[time-nuts] Variation in Radioactive Decay Rate with Solar Activity

[Jose Camara]

You can buy a variety of isotopes from
http://www.spectrumtechniques.com/disc&laminated_sources.htm

Just don't go as far as the "Radioactive Boy Scout" and it shouldn't get you
in any lists that call you to the side in airports...

Hi Brooke,

Maybe. The photon counting gear is pretty trivial. You'd need:

A scintillator
A PMT (Photo Multiplier Tube) and HV stable HV PS.
A preamp
A SCA (Single Channel Analyzer). These can be built.
A counter, stable time base, and data recorder

The main difficulty, IMO, would be getting a sufficient sized lump of the
material. Chunks of Cs don't grow on trees, at least not where I live.

Best,

-John
