RE: NIST Traceable Am-241 Alpha Particle Calibration Standards
We used to buy sources from "The Source" in NM, but they sold out to IPL.
We were pleased with the quality of the electroplated sources, the fact that
the certs were in the units of interest (i.e. 2 pi surface emission), as
well as the price.
