Re: H-3 efficiency on LSC



I counted two different H-3 standards, one an LKB and one a Packard
on the same Liquid Scintillation counter and the efficiencies came out to
be different.  Have any of you experienced that phenomenon? Is there an
explanation for that?
I counted two C-14 standards and they had the same efficiency.
I wonder if it has anything to do with the way the standard was prepared?
