I don't know about reference solutions, but we have purchased a Si-32
reference source for calibration and efficiency measurements of our G-M
tubes.  They cost about $650 and are NIST-traceable.  Si-32 decays to P-32
(half-life=100 years) and the covering shields the low-energy Si-32 beta.
However, this won't help if you're looking to calibrate a LSC (and I'm not
sure what instruments you are calibrating).
