We would also use gamma spec for these situations. One difference, however, is that we are not limited to a single geometry. Our Chemistry department (RP does not operate the gamma-spec) has several different geometries established to allow counting samples of different sizes/configurations.

[mailto:[email protected]] Sent: Monday, May 23, 2016 2:40 PM To: '[email protected]' Subject: [EXTERNAL] [powernet] Offsite Release Question What is you site's process for releasing loose solids and liquids that are not considered bulk releases? At CNS we count all loose solids and liquids on our gamma spec system to environmental LLDs using a calibrated 2000 ml geometry. This process can be cumbersome especially when some of our system oil samples are only 100 mL samples. In that scenario we pull an additional 2000 ml sample so we can count it on our gamma spec system at the appropriate geometry. If anyone has done a study or written a procedure for utilizing a SAM, tool monitor, or other instrumentation for samples less than 2000 ml and would like share it with me, I would appreciate it.
