LUDLUM MEASUREMENTS INC

Ludlum Measurements Inc. specializes in the design, manufacture, and maintenance of precision radiation detection and measurement instrumentation for mission-critical government applications. The company produces handheld survey meters, portal monitors, decommissioning kits, and OEM detection systems engineered for field deployment in nuclear, environmental, and defense scenarios. Their technical expertise spans radiation spectroscopy, gamma and neutron detection, calibration protocols, and ruggedized electronics designed to meet stringent NCRFO and DOE interoperability standards. A key differentiator is their ability to deliver customized instrumentation for confirmatory surveys, emergency response, and regulatory compliance, with proven experience in repairing and recalibrating field-deployed systems to maintain operational readiness. Ludlum maintains consistent relationships with the Environmental Protection Agency, primarily supplying radiation detection equipment for environmental remediation sites and nuclear decommissioning operations. The Department of Defense relies on the company for background meter components and field-ready instrumentation, while the Nuclear Regulatory Commission procures specialized kits for confirmatory surveys. Additional engagements with the Department of Justice and Department of the Treasury reflect applications in border security and nuclear material monitoring. The contractor’s primary focus lies in NAICS 334519, manufacturing other measuring and controlling devices—specifically radiation detection systems—and NAICS 334516, producing analytical laboratory instrumentation for radiological analysis. These verticals position Ludlum as a niche provider of certified, field-deployable radiation measurement solutions for federal environmental, nuclear, and homeland security missions. Ludlum Measurements Inc. is a small business headquartered in Sweetwater, Texas, with no active government certifications. The company operates as a 2L entity, emphasizing direct engineering and manufacturing control to ensure quality and responsiveness in mission-critical procurements. Its geographic footprint and technical specialization make it a trusted supplier for federal agencies requiring reliable, calibrated radiation detection hardware and maintenance services.
