Radiological Physics Associates

What Radiological Physics Associates does

Radiological Physics Associates, Inc. is a privately held medical and health physics consulting firm headquartered in Nashville, Tennessee, founded in 1995. The firm provides a full suite of professional services to medical facilities, industrial clients, and physician offices across the Southeast United States, including diagnostic imaging equipment performance testing, nuclear medicine physics support, radiation shielding design and evaluation, CT dose review, radiation safety officer (RSO) support, radiation safety program audit and development, and ACR and IAC accreditation support. All services are delivered by qualified consulting physicists with expertise in state and federal regulations, MQSA, ACR, and Joint Commission standards; the company reports having served hundreds of facilities across the region over its 30-plus year operating history.

The business operates on a quote-based professional services model with no public pricing and no software or SaaS product. Customer acquisition is driven by a sales-led, consultative approach supported by website-based request forms for quotations, service requests, and shielding design evaluations, supplemented by content marketing through blog posts on regulatory updates and an email newsletter. Existing clients access documentation and submit requests through a ShareFile-based client portal. Revenue is generated entirely from professional services engagements, with e-learning training courses noted as under development to extend the training line.

Company structure is that of a single-office, founder-owned small business: 11-50 employees, no parent company, no subsidiaries, no external funding rounds, no disclosed partnerships, and no public ticker. Operational scope is regional (Southeast US), positioning RPA as a compliance-focused local alternative to larger medical physics groups for facilities that value relationship-driven, credentialed service delivery.

Direct peers

• Krueger-Gilbert Health Physics: Medical and health physics consulting firm offering equipment performance testing, shielding design, and radiation safety program support to healthcare and industrial clients. Directly overlaps with RPA's core service portfolio.
• Radiation Safety Associates: Health physics and radiation safety consulting firm serving medical, industrial, and government clients with shielding design, dosimetry, and RSO services. A direct comparable in the radiation protection consulting space.
• West Physics Consulting: National medical and health physics consulting firm providing diagnostic imaging physics, radiation safety, and accreditation support services. Closely comparable to RPA in service mix and customer base, but operates at broader national scale.
• Radiological and Medical Physics Associates: Independent medical physics consulting practice offering diagnostic imaging physics, nuclear medicine physics, and radiation safety services. A direct small-firm comparable to RPA in scope and delivery model.

Broad incumbents

• Landauer: Established provider of radiation dosimetry, monitoring, and safety services to medical and industrial customers globally. Overlaps with RPA on radiation safety and dosimetry, but operates as a much larger incumbent with product-based revenue.
• Sun Nuclear (Mirion): Provider of quality assurance and dosimetry products for radiation oncology and diagnostic imaging. Adjacent to RPA's ACR/IAC accreditation and equipment testing services via technology-enabled QA tooling.
• Mirion Technologies: Global provider of radiation detection, measurement, and safety solutions serving nuclear, medical, and industrial markets. Comparable through its radiation safety portfolio, though broader in scope and product-heavy versus RPA's pure services model.

Others

• AAPM (American Association of Physicists in Medicine): Professional association for medical physicists that sets standards and provides accreditation resources relevant to RPA's regulatory and accreditation work. Not a commercial peer, but a key ecosystem enabler for the firm's market.
