Re: Liquid Scintillation Counting for I-125

[baumbaugh <baumbaug@nosc.mil>]

        

Lori,

        

I've made
up a number of quench standards for LSC's using I-125.  - Depending
on quench (sounds like a disclaimer) - In an unquenched/minimally
unquenched sample I usually get about 75 - 78 % efficiency with my
Beckman 6000 LSC....The LSC is mostly "seeing" the
betas...

        

P.S. I
understand that the "cooled" LSC's may have a little better
efficiency than my Beckman.

        

Hope this
helps,

        

Joel
