FEMA’s CBRN Test & Evaluation Division is seeking market information on human-portable radionuclide identification devices—SPRDs, RIIDs, SBRDs, and other technologies under 22 lb/10 kg with response within two minutes—for the Komodo Dragon Characterization Test, with interest in COTS, GOTS, and prototype devices at TRL 7+ meeting ANSI/IEC requirements. This RFI is for information-gathering and planning only, creates no contract commitment, and respondents bear their own response costs. Interested vendors would provide device/capability information, replay-tool availability, cybersecurity materials, and the ability to supply six units (or three if opting out of potentially destructive tests) under bailment for environmental, destructive, RASE, and cyber assessments, with participating vendors receiving data for their own instruments. Vendors submitting proprietary information must execute company-to-company NDAs with named government support contractors for review. A virtual vendor Q&A is planned for 9 December 2026, KD CT is expected to start in Q2 FY27, and the anticipated period of performance start date is March 2027.
