About this file
This is a Requirements Matrix attachment to a Request for Information (RFI) for Personal Radiation Detectors (PRDs) issued by the Department of Homeland Security's Federal Emergency Management Agency (FEMA), Office of Chemical, Biological, Radiological, and Nuclear (CBRN) Defense. The matrix establishes technical specifications and performance requirements for commercially available, gamma-detecting PRDs with wireless communication capabilities.
The document outlines 43 operational requirements (ORs) and 12 functional requirements (FRs) organized across six Key Performance Parameters (KPPs). KPP 1 addresses radiation detection capability with gamma-only or gamma/neutron detection (with disabling capability), with probability of detection thresholds at 90% and objectives at 95%. KPP 2 specifies three alarm types (visual, audible, and vibration) with provisions for vibrate-only mode that disables lighted indicators. KPP 3 establishes detection performance metrics including false alarm rates (≤0.25 per hour threshold; ≤0.125 per hour objective), time-to-alarm within 2 seconds at threshold/1 second objective, over-range thresholds of 100 mR/h minimum, and display formats (digital or unit-less). The matrix includes environmental operating specifications spanning -20°C to +50°C temperature ranges, 40-93% relative humidity at threshold/25-99% at objective, IP53 ingress protection at threshold/IP67 at objective, and electromagnetic resilience testing for electrostatic discharge (6 kV), radio frequency fields (80 MHz to 2.5 GHz at 40 V/m threshold/50 V/m objective), and magnetic field exposure (100 A/m). Battery requirements mandate 24-hour operation in non-alarm state at threshold and 168-hour at objective, with 30-minute alarm operation at threshold and 60-minute objective. KPPs 4 and 5 specify physical dimensions (12 cm x 8 cm x 4 cm threshold; 10 cm x 6.5 cm x 3.5 cm objective) and maximum mass of 400 grams at threshold and 240 grams at objective. KPP 6 requires data transmission capability including manufacturer name, instrument model, serial number, software version, detector type, measurement date/time, radiation levels, alarm indication, and operating hours, with mobile application support for both Android and iOS platforms. Cybersecurity requirements mandate Bluetooth 4.2 or higher with FIPS-approved algorithms at threshold and Bluetooth 5.0 at objective, unique logical and physical identifiers, authenticated software updates, operational availability of 98% at threshold and 99.5% at objective, and mean time between failure of 43,800 hours at threshold and 87,600 hours at objective. Mechanical durability testing includes drop tests from 1.5 meters at threshold and 2.44 meters at objective, vibration resilience testing, and impact resistance. The matrix includes vendor response columns for capability assessment (Meets Objective, Meets Threshold Only, Partially Meets Threshold, Does Not Meet Threshold, Not Applicable), basis of response documentation (manufacturer testing, independent testing, product specification, certification/declaration, operational use, analysis, or other), test status and dates, and optional vendor comments.
