Palo Verde does not have Alpha Spec capabilities. We currently use independent laboratories for our Alpha analyses.

Part of our justification for this expense would be to reduce our reliance on independent laboratories for performing alpha characterization (i.e. per the EPRI alpha monitoring guidelines). We currently have Ludlum 3030Ps and MGPI ABPMs which use alpha spec in a limited manner to perform radon rejection, but no true alpha spectroscopy equipment. We would like to know what the rest of the industry is doing; any experience, comments, or feedback are appreciated. Do you have Alpha Spec capabilities at your facility? If so, what equipment do you use? What do you use the equipment for (e.g. radon rejection or a quantitative alpha spectrum of individual nuclides)? If using for alpha spectrum analysis, what energy resolution can you achieve? What type of sample preparation is required? Any other equipment strengths/limitations or lessons learned you would like to share?
