About the company
Radiation Safety & Control Services, Inc., doing business as Rscs, manufactures radiation detection equipment and provides calibration, preventive maintenance, and repair services to federal agencies as a prime contractor, competing predominantly in full-and-open procurements without set-aside designations. The company is a for-profit manufacturer based in Seabrook, New Hampshire, and is a subsidiary of Allied Group Holdings, LLC. Rscs competes primarily under NAICS 338291 (Other Measuring and Controlling Device Manufacturing) and PSC codes aligned with hazard-detecting instruments, laboratory equipment, and environmental services.
The vendor's federal footprint centers on naval radiation safety systems and nuclear regulatory compliance. The Department of the Navy Naval Sea Systems Command dominates the customer base—41 awards (67% of recent activity by count) valued at $5.33 billion in combined potential value, driven almost entirely by a single $6.8 million indefinite delivery contract awarded in 2021 for procurement of MBD-2 battlefield dosimeters, cases, dongles, and related radiation safety services running through May 2026. The vendor has issued multiple delivery orders under this IDC, including a $419.8 thousand order in July 2024, a $378.2 thousand order in September 2023, and earlier tranches for training kits and radiation sources totaling roughly $75 thousand to $139 thousand each. The Nuclear Regulatory Commission Region 1 accounts for a secondary customer concentration—10 awards valued at $71 thousand combined—for calibration, preventive maintenance, and repair of NRC survey instruments under small-business set-asides and unrestricted purchase orders. The Environmental Protection Agency's Office of Air and Radiation awarded a $78.2 thousand purchase order in October 2025 for annual calibrations and repairs of handheld radiation field instruments through October 2030 (base plus four option years), with performance in Las Vegas, Nevada. Rscs also supports the Department of Transportation Maritime Administration (13 awards, $273 thousand) and the Department of Justice Federal Bureau of Investigation (5 awards, $170 thousand).
Concentration by dollar value, however, reveals a large structural outlier. The Department of the Army Acquisition Support Center Joint PEO Chemical and Biological Defense carries 2 awards worth $8.28 billion in combined potential value—likely representing a single large-ceiling IDC or standing offer that has generated minimal actual obligation ($28.6 million obligated across the entire 109-award portfolio, or 0.21% of potential value). This creates a recompete exposure profile that does not reflect day-to-day activity: only 1 award (combined potential value $9 thousand) reaches ultimate completion in the next twenty-four months.
Activity has declined from a 2022 high of 4 awards to 2 awards in 2025 and 2 in 2026 year-to-date. The top parent vehicles are an indefinite delivery contract (N0016717D0005) with 7 task orders valued at $11.7 million combined, two transportation-aligned blanket purchase agreements (DTDTMA1A07006 with 10 task orders, $78 thousand; DTMA91A20110001 with 7 task orders, $195 thousand), and a second Navy IDC (N0016721D0008) with 4 task orders worth $1.1 million combined. Rscs operates as a 100% prime contractor with no recorded sub-awards in the source data, indicating it builds and delivers its own teams and does not serve as a feeder to larger integrators. Service Contract Inventory data shows minimal federal services reporting—3 SCI records, all as a named subcontractor with 18.1 FTEs in FY2022 and 0 FTEs by FY2024—reflecting that the vendor's primary federal revenue flows through goods procurement (radiation detection equipment) and maintenance services purchased as deliverables, not staffing-model federal service contracts above the $150 thousand reporting threshold.
