Radiation Monitoring Devices, Inc.

Radiation Monitoring Devices, Inc., a small-business subsidiary of Dynasil Corporation of America headquartered in Watertown, Massachusetts, designs and manufactures advanced radiation detection instruments, scintillation materials, semiconductor detectors, and specialized imaging systems for federal defense, homeland security, and scientific research customers as a prime contractor (97% of recent awards) under total small-business set-asides. The company competes predominantly under SBIR and STTR programs, with significant exposure to full-and-open, no-set-aside work on larger development contracts and IDIQs.

RMD's customer concentration reflects defense and civilian science dominance. The Department of Homeland Security's Countering Weapons of Mass Destruction office anchors the portfolio by potential value ($48.7 million across 34 awards), followed by the Defense Threat Reduction Agency ($37.8 million across 52 awards). By award count, the Department of Energy and its Office of Science together lead the portfolio (99 and 70 awards respectively), with the National Institutes of Health placing 57 awards. These five customer groupings account for 46% of award volume and 68% of combined potential value. The tension between count and dollars reflects RMD's heavy participation in Phase I SBIR work ($150–300 thousand per award) alongside larger Phase II and Phase III efforts ($1–3 million) and substantial development contracts—notably a $3.8 million cost-plus-fixed-fee CWMD contract for advanced radiation detection instrumentation (awarded June 2023, running through January 2029) and a $2.56 million SBIR Phase III contract with Army Medical Command for dynamic X-ray imaging methodologies (awarded September 2025, completing September 2028).

Recent prime contract examples span multiple agencies and research domains. The Air Force Research Laboratory awarded RMD a $1.25 million SBIR Phase II contract for tunable and reconfigurable metasurfaces enabled by atomic layer deposition of phase change materials (ultimate completion May 2026), and a $1.25 million Phase II contract for chalcogenide-based mid-infrared diffraction gratings (awarded December 2023, completing April 2026). The Department of Homeland Security awarded a $1 million SBIR Phase II for next-generation high-performance semiconductor-based spectroscopic personal radiation detectors (awarded April 2023, completing April 2025). RMD also holds a seat on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ with the Missile Defense Agency, awarded January 21, 2026, carrying a multi-billion-dollar ceiling and ultimate completion through December 2035; a single initial delivery order under SHIELD was valued at $500 and issued January 21, 2026. The company's vehicle footprint is sparse in the source data—the top parent vehicles listed carry only one to two task orders each, indicating either light utilization of traditional IDIQs or concentration of work under direct contract rather than against standing vehicles.

RMD's federal grant footprint is substantial, with the Department of Energy's Office of Science as the dominant grantor. Recent recipient awards include a $152 thousand project grant for spin-polarized electron sources based on Group II-VI compounds grown by atomic layer deposition (awarded September 2024, completing August 2025) and multiple grants for scintillator development, detector arrays, and advanced materials. The National Institute of Mental Health awarded RMD a project grant for an ultra-dense ceramic scintillator for brain positron-emission-tomography scanning (awarded August 2023, completing September 2027). The National Institute of Dental and Craniofacial Research funded a $199 thousand project grant for a semiconductor detector for low-dose, high-resolution dental X-ray imaging (awarded September 2022, completing August 2025). RMD also acts as a sub-recipient on multiple university-led grants, collaborating with the University of California Davis, the University of Tennessee, Pennsylvania State University, Johns Hopkins University, and MIT on specialized detector development, materials characterization, and radiation therapy applications—work typically described as materials synthesis, performance testing, detector fabrication, and technical support across the grant statement-of-work phases.

Activity has remained relatively flat across the past five years (17–22 awards per year from 2022 through 2025), with only six awards recorded in calendar year 2026 to date, likely reflecting the recency of the data snapshot (September 30, 2026). In the next twenty-four months, thirteen awards with combined potential value of $11.9 million will reach ultimate completion and face recompete exposure. SCI-reported service-contract invoicing totaled $3 million across FY2022–FY2024 (zero in FY2025), covering 1.8 down to 1.2 FTEs, indicating that SCI-reportable service work is a small slice of RMD's federal portfolio; the majority of revenue flows through R&D contracts, SBIR/STTR awards, and product sales. Government-paid hourly rates on SCI-reportable prime contracts ranged from $42 to $325 per hour, with a median of $206/hr, and subcontractors performed an average of 12% of prime-contract hours across the seven named subcontractors in SCI records.

RMD operates predominantly as a prime contractor (97% prime split); sub awards are rare, though the company subcontracts to Leidos on autonomous systems design and engineering work for Naval Information Warfare Center Pacific. The company's own use of subcontractors on prime work is light—12% average sub-hours share on SCI-reportable contracts—indicating RMD builds most delivery capability in-house through its own scientific and manufacturing staff. This posture, combined with heavy SBIR/STTR participation and research-grant activity, positions RMD as a specialist in radiation detection materials science, detector fabrication, and advanced optical coatings for federal R&D customers rather than a systems integrator or large-scale service provider.

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.
