How to Register an X-Ray Machine inDelaware: A Simple Step-by-Step Guide

Delaware uses a construction approval and operating approval process for many new and changed X-ray rooms. This page puts the forms and steps in one place.

Heartland Physics can review the project scope and confirm whether its current qualifications and authorization cover any shielding work required for this project. Use the current government sources linked below for registration, plan review, fees, inspections, and filing requirements.

Quick answer

A new facility files ORC-R1. Most new or modified installations above 70 kVp also file OE R-15A with shielding plans before construction.

Delaware issues approval to construct, then approval to operate and a registration permit after the final package and any required inspection.

Start here: forms

What to gather

• Facility and owner information, including EIN or SSN
• Healing-arts supervisor and Delaware professional license number
• Radiation Safety Officer
• Delaware-registered radiation service provider and registration number
• Machine procedures, manufacturer, serial number, installation date, maximum kVp and mA, room, and status
• Scaled room plan, nearby occupancy, equipment location, barrier construction, workload, and shielding calculations

Step 1: Complete ORC-R1

Enter the owner, facility, healing-arts supervisor, Radiation Safety Officer, service provider, procedures, modalities, and every machine. Sign the application. Do not send payment with it.

Step 2: Apply the 70 kVp rule

A new or modified installation above 70 kVp needs an OE R-15A plan-review package before construction.

Equipment at or below 70 kVp does not require a shielding plan; provide the room drawing and the machine and remote-switch locations when requested for facility review.

Step 3: Prepare the plan-review package

The package includes OE R-15A, a scale plan, machine and accessory locations, doors and windows, operator barrier, exposure switch, adjacent occupancy above and below, building materials, proposed shielding, and the service provider’s calculations.

CT submissions include the manufacturer’s iso-exposure curve and qualified medical physicist calculations.

Step 4: Send the construction-review package

Mail it to Delaware Office of Engineering, 43 South DuPont Highway, Dover, DE 19901. Use the official Office of Engineering contact page for plan-review questions. A complete application is normally processed in about two weeks.

Step 5: Wait for approval to construct

Build only after the Office of Engineering issues the Certificate of Approval to Construct. The room must match the approved plan. A major change requires a revised review.

Step 6: Send the facility registration

Mail completed ORC-R1 to Delaware Office of Radiation Control, 417 Federal Street, Dover, DE 19901. Retain a copy. The form asks applicants to allow at least three weeks for processing.

Step 7: Complete operating approval

Provide final machine information, installer records, and any documents requested by the Office of Radiation Control. Delaware may perform a pre-operational inspection. After approval, post the registration permit at the facility.

Step 8: Pay the invoice

Delaware bills the annual registration fee separately, normally in the fall. Do not include payment with ORC-R1; pay the state invoice when it arrives.

Do not make this mistake

Do not begin construction and then request approval. The engineering review is intended to approve the shielding design before the room is built.

How Heartland Physics can help

Heartland Physics can review the Delaware project and confirm whether its current qualifications and authorization cover the shielding work. Delaware requires applicable shielding-plan work to follow its current service-provider and plan-review requirements.
