Here at Los Alamos we use just two of the iSolos. We don't wait before counting, instead we have an expert interpret the spectra.
We have some circumstances where we have thoron progeny giving counts in the 6 MeV region (Bi-212) with its activity driven by the Pb-212 beta emitter with a 10.6 hour half life. There are some "peak-shape fitting" algorithms that could provide better spectra interpretation. Perhaps we can have some discussion on iSolo type counter at the Spokane HPS.

If your station uses the iSolos: * Is there a waiting period before counting a sample using the iSolo in your station procedures? o If so, how long is that waiting period? * Does your station use the pulser for any part of the calibration?
