Radiation Monitoring Devices, Inc.

Radiation Monitoring Devices, Inc., a small-business subsidiary of Dynasil Corporation of America, designs and manufactures advanced radiation detection instruments, scintillation materials, semiconductor detectors, and specialized imaging systems for federal defense, homeland security, scientific research, and civilian agencies as a prime contractor across contracts, grant awards, and an indefinite delivery vehicle seating.

RMD is headquartered in Watertown, Massachusetts, operates as a for-profit manufacturer of goods, and competes predominantly under total small-business set-asides across its prime contract footprint (98% of 671 awards are prime). The company holds no named SBA certifications beyond small-business status in the award records; however, the small-business set-aside designation is consistent across the prime contract portfolio and reflects the company's market posture.

The customer base spans 68 distinct federal agencies, with significant concentration in defense and homeland-security programs. The top five customers by potential value account for 68% of combined potential value: the Department of Homeland Security Countering Weapons of Mass Destruction (34 awards, $48.7 million), Defense Threat Reduction Agency (51 awards, $37.8 million), Department of Homeland Security Office of Procurement Operations (23 awards, $10 million), Department of the Army Materiel Command Research Development and Engineering Command (15 awards, $7.5 million), and Department of the Air Force Materiel Command Research Laboratory (15 awards, $7.2 million). By award count, the Department of Energy and its Office of Science dominate the footprint (99 and 69 awards respectively), followed by the National Institutes of Health (57 awards) and Defense Threat Reduction Agency (51 awards), indicating a split between high-volume scientific and moderate-dollar defense-focused work.

RMD holds a seat on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ with the Missile Defense Agency, awarded January 21, 2026, with a $151 billion ceiling and completion date of December 28, 2035. This vehicle carries a $500 delivery order placed in January 2026 and represents RMD's entry into multi-domain defense system work spanning research and development, prototyping, disruptive technologies, systems engineering, weapon design, production, test and evaluation, cybersecurity, and modernization against air, missile, space, cyber, and hybrid threats. Other parent vehicles identified include several legacy indefinite delivery contracts (DAAL0487C0015, F3361586C4527, N0003985C0504, DAAB0786CP015) with limited recent activity.

Recent prime contract activity centers on small-business innovation research and small-business technology transfer awards in radiation detection and advanced materials. Named examples include a $2.56 million SBIR Phase III contract from the Army Medical Command awarded September 30, 2025, for back-face deformation test methodologies using dynamic X-ray imaging, to run through September 2028; a $1.25 million Air Force Research Laboratory SBIR Phase II contract awarded April 14, 2025, for tunable and reconfigurable metasurfaces enabled by atomic layer deposition of phase change materials, completing June 2027; a $1.2 million Naval Strategic Systems Programs SBIR Phase II contract awarded February 24, 2025, for radiation detection technologies under the "873 Authority" classification, completing August 2026; and a $1.1 million Defense Threat Reduction Agency STTR Phase II contract awarded March 27, 2023, for fast, radiation-hard scintillation materials, completing March 2025. Additional contracts span optical coatings, photonic integrated circuits, ceramic scintillators, semiconductor detectors for medical imaging, and specialized coating technologies. RMD also received a $149,993 Shared Services Center (representing civilian agencies) SBIR Phase I contract in September 2025 for multi-layer optical coatings on curved lenses using atomic layer deposition, and a $199,888.92 Department of Transportation SBIR Phase I contract in August 2024 for low-cost rapid assessment of bridge-deck chloride content in concrete.

Award activity has been stable to declining: 17 awards in 2022, 21 in 2023, 19 in 2024, 17 in 2025, and 4 in 2026 (year-to-date as of April 2026). Sixteen awards (combined potential value $9.3 million) face ultimate completion within the next twenty-four months, representing moderate recompete exposure. Combined potential value across all 671 awards stands at $164.5 million, with combined dollars obligated reaching $375.7 million, indicating a portfolio where actual spending significantly exceeds contract ceilings—typical of research and development work where phase-to-phase progression or option exercises elevate realized value.

Federal grant awards are substantial: RMD acts as prime recipient on 39 Project Grants and one Cooperative Agreement from the Department of Energy Office of Science (CFDA 81.049), the National Institutes of Health, and the National Institute of Dental and Craniofacial Research spanning radiation detection instrumentation, scintillator materials (including ultra-dense ceramic scintillators for brain PET imaging and gadolinium-loaded plastic scintillators), semiconductor detectors, atomic layer deposition coating technologies, neutron detection systems, and sensor platforms for nuclear fuel monitoring. Recent Project Grants include awards in February 2025 for neutron polarizers via supermirrors and fast dense glass for high-energy physics; a $152,000 award in September 2024 for spin-polarized electron sources; and multiple July 2024 awards for doped polymer coatings, non-hygroscopic ceramic scintillators, and autonomous radiation mapping. RMD also receives subcontract awards under prime grantees including the University of California, Davis (pixelated scintillators for cone-beam CT, real-time proton range verification in therapy, Cherenkov charge induction TlBr detectors, high-performance detector modules for PET), the Pennsylvania State University (collaboration on ionizing radiation interaction research), the University of Tennessee (ceramic scintillator development for X-ray radiography and low-cost high-performance detection), Massachusetts Institute of Technology (low-level radiation sensors), and Johns Hopkins University (pixelated scintillators for ultra-high resolution imaging).

Across SCI-reportable service contracts (a subset of federal service work above $150,000), RMD invoiced $3 million in FY2022–FY2024: $1.3 million in FY2022, $872 thousand in FY2023, and $854 thousand in FY2024. SCI-reported FTE delivery declined slightly from 1.8 FTEs in FY2022 to 1.2 FTEs in FY2024, reflecting a shift toward goods manufacturing and R&D contract work rather than service delivery. On SCI-reportable prime contracts, government-paid hourly rates range from $42.25/hr at the 10th percentile to a median of $206.01/hr and $325.02/hr at the 90th percentile, spanning technical and scientific labor. Across SCI-reportable prime contracts, subcontractors performed roughly 15% of total contractor hours on average, with seven named subcontractors identified—indicating RMD builds delivery teams internally for most work but engages specialized subs for specific technical work.

RMD subcontracts to Leidos on autonomous and automated systems design and systems engineering work for Naval Information Warfare Center Pacific (task orders awarded January 30, 2024, and July 2, 2025), representing near-term naval IT modernization engagement. The company does not appear in the source as a prime recipient on government-wide service vehicles or GWACs; its vehicle presence is concentrated on legacy IDICs and the newly awarded SHIELD IDIQ.

The top NAICS categories reflect RMD's research and materials focus: Research and Development in Physical, Engineering, and Life Sciences (116 awards), followed by Semiconductor and Related Device Manufacturing (15 awards) and Analytical Laboratory Instrument Manufacturing (13 awards). Primary performance of work occurs at RMD's Watertown and East Watertown, Massachusetts facilities, with some work performed at Fort Rucker, Alabama (Army Medical Command dynamic X-ray imaging project).

We provide innovative solutions across a broad range of security, medical and industrial applications, including radiation imaging and detection, nuclear instrumentation and non-destructive test equipment. RMD has technology practices in material science, radiation detection, digital imaging technology, magnetic imaging, laser optics and photonics.
