Minimum risk trigger indices
Tingey, F.H. - 2008
A viable safeguards system includes among other things the development and use of indices which trigger various courses of action. The usual limit of error calculation provides such an index. The classical approach is one of constructing tests which, under certain assumptions, make the...

Broadening Industry Governance to Include Nonproliferation
Hund, Gretchen; Seward, Amy M. - 2010
As industry is the first line of defense in detecting and thwarting illicit trade networks, the engagement of the private sector is critical to any government effort to strengthen existing mechanisms to protect goods and services throughout the supply chain. This study builds on previous PNNL...

Use of calibration standards and the correction for sample self-attenuation in gamma-ray nondestructive assay
Parker, J.L. - 2008
The efficient use of appropriate calibration standards and the correction for the attenuation of the gamma rays within an assay sample by the sample itself are two important and closely related subjects in gamma-ray nondestructive assay. Much research relating to those subjects has been done in...
