Radiation detection and monitoring equipment manufacturing
Strategic Profile
Ludlum Measurements is a privately held, family-owned company based in Sweetwater, Texas. Geiger counters manufactured by the company are recognized as a standard reference instrument in occupational safety where exposure to ionizing radiation is a concern. Product lines include radiation detection instrumentation, organic scintillators, photomultiplier tubes, sample counting systems, air monitoring instruments, and electronics design, development, and manufacturing capabilities.
Cyborg Score Rationale
Ludlum holds a dominant, specialized market position in radiation detection with 64-year operating history, diversified product portfolio, and government contracts. However, private ownership limits growth capital visibility, and the niche market restricts total addressable market compared to broader industrial instrument manufacturers.
