Monitoring for Controlled Release

[Peter Fundarek <P.FUNDAREK@utoronto.ca>]

We are currently investigating setting up a system for the controlled release of 
radioactive material following decay in storage.  At this time, we are looking 
at holding liquid P-32 labelled material for a time and then allowing it to be 
disposed in the regular sanitary landfill.  However, we would like to check jars 
of this liquid prior to release to ensure that the levels are below the 
prescribed limits, namely approximately 10 uCi per kilogram.  The jars contain 
the liquid mixed with diatomaceous earth (DE) for stability.  We need the DE due 
to the amount of transport and handling at our facility.  We anticipate having 
to check about 100 bottles per month or more so we need something that can 
handle the volume.

I would be interested in any suggestions or techniques that are currently being 
used by the radsafe community for this procedure.  Any other information or 
suggestions are welcome.
