NRC approval for C-14 light and dark bot

[Herrold@UWYO.EDU (Jim F. Herrold)]

Help requested:

A PhD student brought a proposal to my office yesterday for a study on 
phytoplankton production using the "C-14 light and dark bottle technique" 
common in limnological analysis. What this involves is taking samples from 
lakes in ground glass-sealed bottles, injecting 1-5 microcuries of C-14 
bicarbonate into the bottles and incubating them in the lake for 3-4 hours.

Our NRC license will have to be amended to allow this. In order to speed up 
the approval process, Region IV asked if we could refer to other licensed 
researchers who have been recently approved by the NRC (or State 
authorioties) for a similar process.

Is there anyone out there who has been through such an approval? Please 
e-mail or phone me at the numbers listed below. We are having a Radiation 
Safety Commitee meeting tomorrow (March 14), and I would appreciate any 
information I could get before then.

Thanks
