21. Uncertainties in Internal Gas Counting
Michael P Unterweger, L Johansson, M Rodriques, A Yunoki, Lisa R Karam
The uncertainties in internal gas counting can, for the most part, be split into two areas: counting and sample gas measurement uncertainties and the counting uncertainties. The former includes measurements of counting and sample gas quantities and a ...
22. Validation Testing of Standard Requirements for Backpack-type Radiation Detectors
Technical Note (NIST TN)
Leticia S Pibida, Bruce R Norman
Two gross count and one radionuclide identification backpack-type radiation detectors (BRDs) were used
to validate radiological test requirements listed in the Domestic Nuclear Detection Office (DNDO),
Technical Capability Standard (TCS) for BRDs ...
