​The Department of Defense (DoD) and The Joint Commission require that medical, dental, and industrial x-ray imaging be done in areas where a qualified expert has determined and documented that there is enough radiation shielding to protect employees, patients, and the public. 

A qualified expert is certified by the American Board of Health Physics, the American Board of Radiology, or the American Board of Medical Physics. They must also have knowledge of—

  1. ​The radiation physics associated with the specific devices to be operated within the facility;
  2. The operating characteristics of the devices;
  3. The facility-specific operational practices that will be used;
  4. The operating history (including known problems) of similar devices; and
  5. Applicable regulations and national standards. 

DCPH-A provides radiation shielding design services to the DoD by employing qualified experts who meet these requirements. Contacting DCPH-A early in the process of designing new x-ray imaging facilities can help you save time and money in getting the facility into compliance. 

Based on your facility description and its intended use, DCPH-A will provide you a report describing what steps, if any, need to be taken to ensure the safe and regulatory compliant operation of your x-ray imaging facility.​

What Information Will DCPH-A Need?

Download the X-Ray Shielding Design Services Checklist​ to help you gather the i​nformation we'll need. Once you've requested our services, a Health Physics Division point of contact will assist you through the completion and submittal of the checklist.


  • The manufacturer and model of the x-ray imaging equipment being used and the type of x-ray imaging facility (e.g., radiographic, fluoroscopic, angiography, dedicated chest installation, mammographic, computed tomographic, mobile radiography, mobile O-arm and fluoroscopy system, dental x-ray facilities, veterinary, industrial x- ray facilities, and so forth). Provide all information from the manufacturer, including product brochures, user's manuals, pictures of labels on the device, and field reports.​
  • A floor plan of the area that includes, at a minimum: 
    • Complete dimensions
    • The location and orientation of the x-ray equipment in the room where it will be used
    • The locations of—
      • The control room, doors, and chest bucky (if applicable) in the room;
      • The patient or object being imaged; and
      • All immediately adjacent rooms and hallways.
    • Height of the room and height of the space below the x-ray room
  • What the adjacent rooms and the rooms above and below the imaging room are used for (e.g., exam rooms, clerical offices, rest rooms, and so forth). If a space is restricted to x-ray personnel, that should be noted.
  • The composition (gypsum wall board, concrete, lead, and so forth) and thickness of any wall, ceiling, or floor with a potentially occupied space (including outdoor areas) on the other side. Include composition of any doors and windows in the room with the x-ray device.
  • The number of patients/objects expected to be imaged each week and the number of x-ray shots for each patient. If an x-ray device performs multiple functions or orientations (e.g., chest bucky shots and table shots), include the number of shots for each orientation. If the x-ray device is industrial and does not involve patients, state the amount of time per week that the device is on and a description of what is being x-rayed.
