The Comprehensive Nuclear-Test-Ban Treaty limits radiation measurements during an on-site inspection to those isotopes the States Parties have agreed are appropriate for the purpose of determining if a nuclear explosion has occurred without revealing irrelevant confidential information. To accomplish this, the radiation detectors used will need to have measurement restrictions that are proven to function reliably over the wide range of possible inspection uses and scenarios. In order to provide a basis set of spectra for testing proposed measurement restriction systems, PNNL and LLNL defined a set of treaty-compliant and non-compliant scenarios and then independently developed a set of spectra relevant to those scenarios. Real spectra were utilized to the extent possible, but often computer simulations were necessary. These spectra will next be used to assess the performance of an INL measurement restriction system.
