Overhoff Technology

Overhoff Technology is a radiation-monitoring equipment company based in Milford, Ohio. The business was founded in 1972 by Mario Overhoff in Cincinnati under the name Overhoff and Associates. Its core activity is the design, construction, and sale of instruments used to detect and measure radioactive materials, with particular emphasis on tritium monitoring. The company’s product range includes systems for identifying tritium contamination on surfaces and measuring tritium concentrations in air, water, and seawater. It also produces radon air-monitoring equipment and related radiation-detection systems. These products are intended for environments in which radioactive contamination or exposure must be monitored, including nuclear power stations, nuclear research facilities, pharmaceutical laboratories, industrial manufacturing sites, and military and government applications. The company’s products are described as ISO 9001 certified. Overhoff remained an independent specialist business for several decades before changing ownership. In 2007, it was acquired by Robert Goldstein, who was also chief executive of Technical Associates, associated with Optron Scientific Corp. In 2010, Overhoff entered a partnership with Locus Technologies focused on tritium monitoring for the nuclear industry. The relationship reflected the company’s role as a specialized instrumentation provider serving nuclear and regulated industrial customers. By 2015, Overhoff Technology was operating as a subsidiary of US Nuclear Corp. US Nuclear was cleared by FINRA in February of that year to become publicly traded under the symbol UCLE on the OTC Bulletin Board. Overhoff therefore became part of a broader group focused on radiation detection and nuclear-sector instrumentation rather than a separately listed company. Public information also indicates that the group’s businesses had received contracts from the United States Department of Defense by 2020. In February 2025, US Nuclear Corp announced a consolidation involving its Optron facilities in Los Angeles and the Overhoff Technology facility in Milford, Ohio. The announcement represented a corporate and operational reorganization of the parent group. Available reference material does not establish that the Overhoff brand itself was discontinued, nor does it provide a new standalone headquarters or a separate public listing. Overhoff is best understood as a specialist industrial technology brand within US Nuclear Corp, serving customers that require radiation and radioactive-contamination measurement in civilian, scientific, industrial, defense, and government settings.

Overhoff Technology originated in Cincinnati in 1972, when Mario Overhoff established the business under the name Overhoff and Associates. The company developed as a specialist manufacturer of radiation-detection instruments, eventually adopting the Overhoff Technology name and relocating its base to Milford, Ohio. Its technical focus centered on monitoring radioactive materials and contamination, particularly tritium, a radioactive isotope relevant to nuclear power, research, industrial, and defense applications. The company’s principal capabilities include the design and manufacture of tritium monitors for several sampling environments. Its systems have been described as capable of detecting tritium surface contamination and measuring tritium in air, water, and seawater. Overhoff also produces radon air monitors. The stated customer base spans nuclear power plants, nuclear research organizations, pharmaceutical laboratories, industrial manufacturers, and military and government users. Its products are described as ISO 9001 certified, supporting its positioning as a quality-managed supplier of specialized instrumentation. A significant ownership change took place in 2007, when the company was bought by Robert Goldstein, chief executive of Technical Associates, a business associated with Optron Scientific Corp. The acquisition connected Overhoff with a wider group of companies involved in radiation detection and related scientific equipment. In 2010, Overhoff partnered with Locus Technologies on tritium monitoring for the nuclear industry, extending its collaboration around software, monitoring, or technical solutions for a highly regulated market. By 2015, Overhoff Technology was identified as a subsidiary of US Nuclear Corp. In February of that year, US Nuclear was cleared by FINRA to become publicly traded under the ticker UCLE through the OTC Bulletin Board. Overhoff was not separately listed; its corporate identity and operations were situated within the parent company’s broader nuclear-monitoring portfolio. Public reference material later indicated that US Nuclear Corp had been awarded United States Department of Defense contracts by 2020, placing the group’s products within a government and defense procurement context as well as commercial and scientific markets. The most recent organizational development in the available material occurred in February 2025. US Nuclear Corp announced the consolidation of its Optron facilities in Los Angeles and its Overhoff Technology facility in Milford, Ohio. The announcement indicates a restructuring or integration of facilities within the parent group, but the available sources do not state that the Overhoff brand was terminated. Nor do they provide details on staffing, production transfers, financial effects, or a replacement location. Overhoff Technology therefore remains documented as a specialized radiation-monitoring business associated with US Nuclear Corp, with its identity rooted in tritium, radon, and radioactive-contamination measurement equipment.
