About Radiation Safety & Control Services, Inc.
Radiation Safety & Control Services, Inc. (doing business as Rscs), a small-business manufacturer of radiation detection equipment and calibration services based in Seabrook, New Hampshire, operates exclusively as a prime contractor (100% of recent awards) supplying dosimetry devices, survey instruments, and maintenance services to federal customers. Rscs is a child entity of Allied Group Holdings, LLC; the company competes predominantly on full-and-open awards with no set-aside designation, though several small-business set-asides appear in its recent work.
Rscs's customer base shows extreme concentration on Naval Sea Systems Command, which anchors 41 awards (67% of award count) carrying $5.33 billion in combined potential value — a figure driven by a single $6.8 million indefinite delivery contract for MBD-2 battlefield dosimeters, cases, and accessories established in 2021 and running through May 2026. This IDC generates a stream of delivery orders; representative recent work includes a $419.8 thousand order placed in July 2024 for MBD-2 dosimeters and a $311.9 thousand order awarded in March 2026 for dosimeters and cases. Outside Navy, Rscs holds smaller customer relationships with the Department of Transportation Maritime Administration (13 awards, $273 thousand combined potential value), the Nuclear Regulatory Commission Region 1 (9 awards, $61 thousand), and the Environmental Protection Agency (4 awards, $424 thousand). The EPA work includes a $38.2 thousand purchase order awarded in October 2025 for annual calibrations and repairs of handheld radiation field instruments through October 2030 (base plus four option years). However, the top-customers-by-potential-value ranking diverges sharply from volume; the Department of the Army Acquisition Support Center Joint PEO Chemical and Biological Defense appears with only 2 awards but $8.28 billion combined potential value, indicating a major procured capability not yet flowing through orders.
Rscs places task orders under three parent vehicles: the Naval Sea Systems Command IDC N0016721D0008 (4 task orders, $1.1 million combined potential value), the Army IDC W9124Q08D0816 (2 task orders, $256 thousand), and two Department of Transportation Maritime Administration BPAs generating modest combined values of $78 thousand and $195 thousand respectively. Activity has decelerated over the past five years — from four awards in 2022 to one in 2026 (the March 2026 dosimeter order noted above). Only 2 awards ($322 thousand combined potential value) reach ultimate completion in the next twenty-four months, creating minimal recompete exposure in the near term; the Navy IDC N0016717D0005 and Army W9124Q08D0816 both carry multi-year authority extending beyond that window.
Work scope centers on radiation detection and measurement products: MBD-2 dosimeters, RadTag training equipment, TWR Mini-Source radiation sources, Radeye survey meters, and field instrument calibration and repair. The top NAICS category across the portfolio is Other Measuring and Controlling Device Manufacturing (42 awards), followed by Environmental Consulting Services (20 awards) and Maintenance/Repair services (8 awards). Rscs operates purely as a prime contractor with no identified subcontractor footprint in recent awards. Service Contract Inventory reporting shows minimal SCI-captured activity — three sub-engagement records between FY2022 and FY2024 — indicating that most Rscs work consists of goods procurement and maintenance rather than labor-intensive service delivery above the $150,000 SCI threshold.
