About Radiation Physics Consultants, Inc.
Radiation Physics Consultants Inc., a Duluth, Minnesota–based small business subchapter S corporation, provides medical physicist and radiation safety officer services to federal healthcare facilities as a prime contractor exclusively across two customer agencies. The company competes predominantly under total small business set-asides across its contract footprint.
Radiation Physics Consultants operates as a specialized provider of medical physics and radiation safety services for Indian Health Service and Department of Veterans Affairs facilities serving American Indian, Alaska Native, and veteran populations across the Upper Midwest and Northern Plains. The company's capability portfolio centers on board-certified and board-eligible medical physicist services, including radiation safety inspections, equipment evaluations, dosimetry program management, and compliance oversight for radiological modalities such as X-ray, CT, MRI, nuclear medicine, ultrasound, and dental imaging equipment. Representative prime work includes a $155,820 definitive contract awarded by Veterans Integrated Service Network 23 in September 2025 for comprehensive radiation safety officer services at the Fargo VA Healthcare System and its Community-Based Outpatient Clinics in North Dakota and Minnesota; a $95,140 purchase order from the Indian Health Service in July 2025 for medical physicist services in Harlem, Montana; and a $312,223.83 purchase order from VISN 23 in January 2025 for annual radiation inspection and equipment testing services across the Fargo system's CT, MRI, nuclear medicine, and dental x-ray equipment.
Customer concentration is bifurcated and stable. The Indian Health Service accounts for 25 awards and $1.4 million in combined potential value, while Veterans Integrated Service Network 23 (VA) accounts for 14 awards and $1.7 million — together representing 100% of recent awards. The VA's slightly higher dollar share reflects a mix of larger definitive contracts and ongoing radiation inspection purchase orders, while IHS awards trend smaller with higher count. The company holds a single indefinite delivery contract (75H70620D00031) underlying five task orders with $408 thousand in combined potential value, primarily supporting the Rosebud Comprehensive Health Care Facility in South Dakota.
Award activity has remained modest and flat over the past five years — four awards in 2022, two in 2023, two in 2024, four in 2025, and one in 2026 — with combined potential value of $3.1 million across 39 prime awards. Only two awards face ultimate completion within the next twenty-four months (combined potential value $41 thousand), limiting near-term recompete exposure. The vendor operates as a pure prime (100% prime awards, no subcontractor role), delivering services directly to federal healthcare customers rather than as a sub to larger contractors.
