Attachment 1: Draft Requirements

Key Performance Parameters (KPP) that must be met at the threshold level to be considered as a viable option are noted by a bold KPP in the ID # column of the requirements table. Some requirements have unique sub-requirements for detection as it relates to specific radionuclides; references to these radionuclides can be found in Appendix 1, Tables 1-5.

The requirements are derived from a series of sources. These include:

• “Technical Capability Standard for Handheld Instruments Used for the Detection and Identification of Radionuclides,” (TCS) Document #500-DNDO-117250v0.00, Date Revised: October 2011. The handheld instruments TCS was published in accordance with the SAFE Port Act [H.R. 4954-16, Subtitle C-Port Operations, Section 121(f) Standards] and provides performance requirements for radionuclide detection and identification of selected industrial and special nuclear materials (SNM), both bare and shielded, and detection and identification of SNM under conditions of masking by industrial, medical, or NORM sources.
