Re: Flourimeter

Uranium by fluorimetry works very well down to approximately 3 micrograms per liter.  The drawback for HP types is that it works for total uranium, by which I mean that no isotopic info is available.  To convert to activity you have to know (or assume) something of the isotopic ratios.

I hoping someone on radsafe might be able to provide me with some insight
to a detection method that I have been unable to find more information on.
The process is for uranium bioassay (circa 1960's) which involed drying an
aliquot of sample on a platinum disk and drying.  The disk was then
covered with a sodium flouride pellet and counted in a flourimeter.  I
understand the theory behind the counting technique but I was hoping
someone might have an idea of the efficiency or minimum detection limit
for measuring by this method. Thanks in advance for any information.
