NAICS 334517 – Irradiation Apparatus Manufacturing encompasses the design, development, and production of specialized equipment used to generate and control ionizing radiation for medical, industrial, and research applications. This includes devices such as gamma irradiators, electron beam accelerators, X-ray irradiation systems, and radioisotope-based treatment units. These apparatuses are critical in sterilizing medical devices, preserving pharmaceuticals, enabling cancer radiotherapy, and supporting materials testing. In the federal contracting landscape, this NAICS code serves as a niche but essential component of biomedical infrastructure, supporting mission-critical procurement by agencies requiring validated, FDA-compliant, and radiation-shielded systems. The manufacturing process demands precision engineering, regulatory compliance under NRC and FDA guidelines, and adherence to strict quality control standards such as ISO 13485. Marathon Medical Corporation is the leading contractor in this sector, recognized for its expertise in delivering calibrated, safety-certified irradiation systems tailored for clinical and laboratory environments. As a specialized prime contractor with deep technical capabilities in radiation safety and medical device integration, it dominates the space through long-term maintenance contracts and system upgrades, often partnering with small businesses for component supply and calibration services. The Department of Veterans Affairs is the primary federal buyer, procuring irradiation apparatuses to support VA medical centers’ oncology and sterilization programs. Demand is driven by the need to maintain sterile surgical instrument supplies and deliver targeted radiotherapy treatments to veteran patients, particularly in high-volume VA hospitals and regional healthcare hubs. The competitive landscape is concentrated, with limited manufacturers possessing the regulatory certifications and engineering rigor required for federal procurement. Opportunities exist for firms with expertise in radiation shielding, control system integration, and FDA 510(k) submissions, particularly those able to offer lifecycle support and remote monitoring capabilities. Recent trends indicate growing emphasis on modular, upgradeable systems to extend equipment lifespan and reduce total cost of ownership.
Small Business Size Standard
The SBA threshold that decides who can bid NAICS 334517 work as a small business.
The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.
13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
