Re: Spiked Fish for Gamma Spec

["Robin Cooksey" <Robin.Cooksey@tdh.state.tx.us>]

Its been a few years since I worked in a radiochemistry but we would 
take the entire fish and grind it up in a regular meat grinder. 
Formaldehyde is added as a presevative. Three separate sub-samples are 
prepared. A specified amount of EPA-supplied "spike" is added to one 
of the subsamples.  The second subsample is used as a duplicate. For 
vegetation, we used shredded bio-bags saturated with the std soln, it 
was as close appoximation we could come up with that would not 
decompose with the addition of formaldehyde.
