Attachment 2 - Sole Source Justification Redacted.pdf

This is a Determination & Findings document for a single source procurement justification by the Air Force Radiation Assessment Team (AFRAT) under the PZIBA contracting activity.

The procurement concerns the RS-700 Mobile Radiation Monitoring System, a self-contained gamma-ray and neutron radiation detection and monitoring system designed for mounting on land vehicles, aircraft, or fixed locations. The system utilizes an Advanced Digital Spectrometer (ADS) to provide real-time search, surveillance, radioisotope identification, and GPS-linked radiation mapping capabilities. Key components include the RS-705, RSX-1, RSNS-2S, LI battery, and cable set. The contracting officer has justified a sole source award to Radiation Solutions Inc (RSI), citing that RSI is the only manufacturer and authorized reseller of the RS-700 system. The determination notes that extensive market research confirms no other sources are available, and the RS-700 is essential to AFRAT's mission as a critical assemblage component. The justification emphasizes that only RSI can guarantee flawless integration into the predefined AFRAT deployment footprint, provide direct warranties, and deliver specialized training, with other comparable systems lacking the specific integrated features required. The single source authority is cited under RFO 12.102(a) for commercial products and services. The determination was signed on August 18, 2026.
