Gamma Products Inc.

Gamma Products Inc., based in Worth, Illinois, manufactures and services specialized radiation detection instruments and laboratory equipment for federal agencies as a prime contractor (98% of recent awards), competing in unrestricted, full-and-open procurements with no set-aside designations. The company has held federal contractor registration since 2002 and operates across analytical laboratory instrumentation, gamma spectroscopy systems, and proportional counter maintenance supporting environmental, defense, and research missions.

Gamma Products' capability portfolio centers on gas proportional counters (GPC), alpha-beta particle detectors, gamma spectroscopy equipment, and associated maintenance and field service. Recent representative work includes a $139,666 firm-fixed-price contract awarded by the Army Research, Development and Engineering Command in June 2024 for preventative maintenance of high-purity germanium gamma spectroscopy units and alpha-beta gas flow proportional counters at Aberdeen Proving Ground, Maryland, running through June 2029 with four optional renewal periods; a $274,360 firm-fixed-price maintenance contract from the Army Aviation and Missile Command awarded in May 2024 covering test, measurement, and diagnostic equipment support through May 2029; and a $126,547 three-year maintenance agreement with HHS's Office of Administration and Resource Management for gas proportional counter support services awarded in August 2024, with the base year running through November 2025. The company also supplies discrete instruments — a $115,000 purchase of a G542-16 multi-detector low-level alpha-beta counter to EPA's Office of Air and Radiation in June 2024 and an $80,000 G5420-112C autoquad gas proportional multiple detector, also to EPA, the same month.

Customer concentration reflects a dual focus on defense and environmental agencies. The top five customers by award count account for 53% of recent awards, anchored by the Department of the Air Force (20 awards, $104 thousand combined potential value), the Army Aviation and Missile Life Cycle Management Command (17 awards, $1.3 million), the Army Research, Development and Engineering Command (11 awards, $481 thousand), EPA's Office for Air and Radiation (9 awards, $723 thousand), and the Navy Naval Sea Systems Command (8 awards, $52 thousand). When ranked by potential value, the Army Aviation and Missile command dominates (17 awards, $1.3 million), followed by DOD's Uniformed Services University of the Health Sciences (5 awards, $1 million), EPA (combined across two offices, $1 million), and RDECOM (11 awards, $481 thousand). Gamma Products places task orders under two GSA Federal Supply Schedules (GS00F11024 and GS24F1123B, five task orders each), a blanket purchase agreement with the Army (HU000116AJV14), and legacy indefinite-delivery contracts with the Army and Air Force. Activity has remained modest — two prime awards in 2022 through seven in 2024, with only one awarded in 2025 and one in 2026 — and only two awards (combined potential value $168 thousand) face ultimate completion within the next twenty-four months, presenting minimal near-term recompete exposure. Gamma Products subcontracts to Hanford Laboratory Management and Integration LLC on gas proportional counter maintenance and multi-channel analyzer upgrade work supporting the 222-S Laboratory Complex, with subaward dates in September 2024 and March 2025.
