US Nuclear designs and manufactures radiation detection and monitoring equipment through three divisions: Technical Associates, Overhoff Technology, and Electronic Control Concepts. Technical Associates produces general radiation monitors, such as handheld meters, personal dosimeters, and port security scanners. Overhoff Technology focuses on tritium detection for air and water, providing specialized instruments for nuclear facilities. Electronic Control Concepts manufactures test and maintenance meters for medical and industrial x-ray machines. US Nuclear sells hardware, software, and services directly to government agencies and regulated industries, including nuclear power plants, national laboratories, the US military, and healthcare providers. The business model relies on equipment sales and recurring service contracts, supported by mandatory regulatory requirements for radiation monitoring in its core markets. US Nuclear designs its products in-house and owns its technology suite. The company's growth strategy emphasizes the global expansion of next-generation nuclear reactors, such as Molten Salt Reactors and Liquid-Fluoride Thorium Reactors, which require more intensive tritium monitoring than conventional reactors. US Nuclear also provides drone-mounted radiation detection systems through a partnership to support aerial surveys.
