UNSPSC 41113115: Radon detectors

UNSPSC 41113115 Radon detectors (Commodity) describes detection and monitoring equipment for gas-phase environmental hazards, though recent state and local solicitations under this code show little relevance to radon detection per se. Instead, state and local bodies are using this code to tag detection systems for methane, particulate matter, digester gas, oxygen monitoring, and broader environmental lab and analytical instrumentation. The Orange County Transportation Authority issued an IFB on June 4, 2026 for methane detection system service and maintenance across five transit facilities, including triannual calibration, unscheduled labor, and repair parts under a four-year, $260,000 contract. The City of Fort Worth posted an RFQ on March 16, 2026 for portable real-time particulate matter monitoring equipment for field environmental inspections, due March 23, 2026. Other solicitations tagged to this code include University of Wisconsin-Madison's request for a simultaneous thermal and gas analysis system (IFB posted July 9, 2026, due July 17, 2026), the Eastern Municipal Water District's design-build-finance-operate proposal for digester gas utilization across three regional water reclamation facilities (RFP posted February 24, 2026, due April 14, 2026), and Greenville County's request for landfill gas and air quality consulting services at three county landfills (RFP posted February 27, 2026, due April 1, 2026). The issuing-body mix includes county transportation authorities, municipal environmental and water utilities, county waste management operations, cities, school districts, and higher-education institutions across diverse jurisdictions.

Recent activity under this code spans California, Florida, Michigan, South Carolina, Texas, and Wisconsin. The mismatch between the code's nominal scope (radon detectors) and what is actually being solicited suggests either miscoding or a broad internal classification scheme where detection and monitoring instruments cross commodity boundaries. Procurement is fragmented across different environmental and utility agencies rather than concentrated among repeat buyers, with few bodies posting multiple opportunities under this code in the recent window. Geographic concentration is thin; no single state or region shows dominant activity. The code appears undersized relative to the diversity of detection-system work being bought—suggesting either narrow adoption within state and local procurement offices or systematic miscoding that obscures real demand for environmental detection and analytical instrumentation services.
