Diagnostic Radiation Physics Services (DRPS) provides comprehensive medical physics and radiation safety consulting to imaging facilities throughout Wilmington, Delaware. Wilmington is the largest city in Delaware and the county seat of New Castle County, situated in the northern corner of the state at the confluence of the Christina and Brandywine rivers. New Castle County is the most populous county in Delaware and forms the core of the Philadelphia-Camden-Wilmington metropolitan statistical area. DRPS serves facilities in Wilmington and across New Castle County, including the Brandywine Valley corridor, and extends coverage into adjacent Chester County and Delaware County in Pennsylvania to the north, Cecil County in Maryland to the west, and across the Delaware River into Salem County and Gloucester County in New Jersey.
Medical Physics Services in Wilmington
DRPS delivers the full range of diagnostic medical physics services to Wilmington-area imaging centers, hospital-based radiology departments, specialty clinics, and multi-site healthcare organizations:
- Equipment Performance Evaluations (EPEs): Annual and baseline physics testing for radiographic, fluoroscopic, mammography, CT, and other modalities, meeting Delaware regulatory requirements and national accreditation body standards.
- Radiation Shielding Design & Certification: Workload-based shielding calculations for new imaging suites and facility renovations across New Castle County and the greater Wilmington area, with post-construction verification surveys and physicist certification letters.
- Radiation Safety Officer (RSO) Services: Named RSO consulting for facilities using radioactive materials, including radiation safety program administration, staff training, dosimetry oversight, and regulatory correspondence with both the Delaware Office of Radiation Control and, where applicable, the NRC Region I office.
- Accreditation Support: Physics testing, image quality review, and documentation preparation for ACR, IAC, RadSite, and Joint Commission accreditation and reaccreditation.
- CT Physics Testing: Comprehensive CT performance evaluations—image quality metrics, dose characterization, and accreditation-ready written reports—for single-scanner and multi-CT environments.
- PET/CT & Nuclear Medicine Physics: Acceptance testing, annual physics surveys, and radiation safety program support for PET/CT systems and nuclear medicine departments.
- Quality Assurance Programs: Facility-specific QA protocols and staff training programs suited to modality mix, patient throughput, and applicable regulatory and accreditation obligations.
Delaware Radiation Regulations
Radiation safety oversight in Delaware is administered by the Delaware Division of Public Health, Office of Radiation Control, operating under the Delaware Department of Health and Social Services. The Office registers and inspects x-ray equipment and certain radioactive materials throughout the state, including in Wilmington and New Castle County.
Key regulatory points for Wilmington facilities:
- X-ray equipment registration: All diagnostic x-ray equipment in Delaware—radiographic, fluoroscopic, mammographic, CT, and other systems—must be registered with the Delaware Office of Radiation Control and operated in compliance with state radiation protection standards.
- Radioactive materials: Delaware is not an Agreement State with the NRC. Wilmington facilities that use reactor-produced radioactive materials (as in nuclear medicine and PET/CT) are licensed directly by the U.S. Nuclear Regulatory Commission (NRC) Region I, headquartered in King of Prussia, Pennsylvania. DRPS supports both Delaware state compliance and NRC licensing simultaneously.
- Mammography: FDA/MQSA regulations apply statewide, independent of state registration.
- Accreditation: ACR, IAC, RadSite, and Joint Commission accreditation programs impose physics testing and documentation requirements that apply regardless of state licensure status.
DRPS assists Wilmington facilities with Delaware Office of Radiation Control registrations, NRC license applications and renewals, inspection preparation, and accreditation documentation.
Why Wilmington Facilities Choose DRPS
Regional reach in a multi-state metro. Wilmington sits at the center of a tri-state healthcare market: New Castle County borders Pennsylvania to the north and Maryland to the west, and the Wilmington metro is formally included in the Philadelphia-Camden-Wilmington MSA. Healthcare systems serving Wilmington frequently operate facilities across multiple states. DRPS provides medical physics services in Delaware, Pennsylvania, Maryland, and New Jersey, enabling coordinated multi-state physics programs under a single consulting relationship.
Dual-regulatory expertise. Because Delaware is not an NRC Agreement State, Wilmington facilities with nuclear medicine or PET/CT programs must comply with both Delaware Office of Radiation Control requirements (x-ray and certain materials) and NRC Region I requirements (reactor-produced radioactive materials). DRPS navigates both frameworks and manages regulatory correspondence across agencies on behalf of the facility.
Board-certified, independent physicists. DRPS physicists hold board certification through the American Board of Radiology (ABR) or American Board of Medical Physics (ABMP). As an independent consultancy, DRPS has no equipment vendor relationships—recommendations reflect the needs of the facility.
Accreditation program experience. DRPS structures physics testing, image quality assessments, and written reports to meet ACR, IAC, RadSite, and Joint Commission documentation requirements, reducing preparation time and submission re-work.
Frequently Asked Questions
What medical physics services does DRPS provide in Wilmington? DRPS provides equipment performance evaluations (EPEs), radiation shielding design and certification, RSO services, CT physics testing, PET/CT and nuclear medicine physics, and accreditation support (ACR, IAC, RadSite, Joint Commission) for imaging facilities in Wilmington and throughout New Castle County and the greater Wilmington region.
Does Delaware require x-ray equipment registration? Yes. The Delaware Division of Public Health, Office of Radiation Control requires all diagnostic x-ray equipment in Delaware to be registered and inspected. DRPS can assist with registration documentation and ensure equipment performance meets state standards.
Is Delaware an Agreement State for radioactive materials? No. Delaware is not an NRC Agreement State. Wilmington facilities that use reactor-produced radioactive materials in nuclear medicine or PET/CT are licensed directly by NRC Region I, not by a state agency. DRPS supports both NRC licensing and Delaware state compliance.
Can DRPS support a Wilmington facility that also has locations in Pennsylvania and Maryland? Yes. DRPS provides medical physics services across Delaware, Pennsylvania, and Maryland—all states where DRPS operates—making it practical to manage a multi-state imaging program under a single physics consulting relationship with consistent protocols and reporting.
What accreditation bodies does DRPS support for Wilmington imaging facilities? DRPS provides physics testing and documentation for ACR (mammography, CT, MRI, nuclear medicine, PET, ultrasound), IAC, RadSite, and Joint Commission accreditation programs. We tailor the scope of services to the specific modalities and accreditation requirements of each facility.
