CWMD Securing the Cities (STC) Personal Radiation Detectors (PRD) RFI

The Department of Homeland Security's Countering Weapons of Mass Destruction (CWMD) Office is conducting market research through this Request for Information to identify Commercial Off-The-Shelf (COTS) Gamma detecting Personal Radiation Detectors (PRDs) for the Securing the Cities program. The agency seeks detailed technical specifications for PRDs that must meet stringent operational requirements including 80-95% probability of detection, compact dimensions (10-12 cm x 6.5-8 cm x 3.5-4 cm), maximum weight of 240-400 grams, and battery life ranging from 24-168 hours. Vendors must provide comprehensive information about their devices' technical capabilities, data transmission features, production capacity, pricing, and additional functionalities such as total dose tracking, radionuclide identification, and geospatial positioning. The devices must demonstrate cybersecurity compliance, environmental durability across temperatures from -20°C to +50°C, and compatibility with Android 12+ and iOS 16+ mobile platforms. Responses are due by 5:00 PM Eastern on September 29, 2025, submitted via email to William Grimm, with submissions limited to 10 pages excluding cover pages and device pictures.

This pre-solicitation notice does not include any set-aside designations, though the government has expressed particular interest in responses from small businesses, including 8(a), Historically Underutilized Business Zone, and Service-Disabled Veteran Owned Small Businesses. No current contractors or incumbents are identified in the documentation, and no decision has been made regarding the small business strategy for any potential future acquisition. The RFI does not specify award values, budget ranges, or quantities of devices needed, as this is purely a market research exercise at this stage. The technical requirements matrix outlines 41 operational requirements and 12 functional requirements that potential devices must satisfy, indicating a comprehensive evaluation framework for future procurement decisions. The two-month response period from July 29 to September 29, 2025, provides vendors adequate time to prepare detailed technical submissions demonstrating their PRD capabilities against the government's specified thresholds and objectives.
