Re: [Phys-l] Fwd: decay constant variation and solar flares?!

A scintillator company in error sent us one of their Cs-137 "doped" NaI (Tl) crystals. I thought the inclusion of the Cs was for energy calibration -- maybe for sensitivity also?

p.s. I have a bunch of fast LEDs used to test -- calibrate plastic scintillators surplussed by SLAC. They screw into a nut embedded in the plastic.

There are many ways to check for such suspected artifact. One way to check for the stability NaI detector response would to expse it to send signals from a generator of light pulses (of constant amplitude and frequency). They probably did the, during the same experiment, placing the control peak above the soectrum ending. Or something similar.
