An architect’s guide to X-ray room requirements

What do I need in an X-ray room? Discover the correct X-ray room requirements to ensure you design a safe and accessible space for radiology.

 The global X-ray systems market was valued at $6.7 billion in 2021, with a CAGR of 2.3% predicted up to 2030. Meeting the demand proposed by technological advances, investments, and product development make it a real challenge to design an X-ray room that’s both practical and safe. In this essential architect’s guide, we share essential specifications, dimensions and requirements to ensure your provisional plans are viable.

What is an X-ray room?

Also called a “Radiology room” or “Radiographic Imaging room”, an X-ray room is a designated space for various X-ray procedures. It must provide the appropriate space for radiographers to perform procedures while remaining a safe space for patients and staff. As the space is designated for specific procedures, most X-ray rooms are as small as possible to save space for other medical departments. Therefore, architects must utilise the space effectively without sacrificing the quality of care or application of procedures.

The Optimal X-ray Room Layout

At Raybloc, we recommend X-ray rooms be placed in the lowest part of a building to reduce the possibility of radiation travelling through the floor. If you have no choice but to locate the X-ray room on an upper level of the building you may require lead lining to the floor area – An RPA report will be required to determine the levels of protection and location of the lead lining.

Secondly, the most crucial area of the X-ray/CT room is the control area. From here, the radiologist should have sight of the patient through the screen and operate the equipment. This area must remain protected with lead-lined screens, windows, walls, and doors. This is particularly essential if the radiologist performs procedures regularly.

Space is another factor to consider. The X-ray room must be attributed to the system itself and include the following components:

  • A power generator
  • X-ray tube
  • Collimator
  • Tube stand
  • Radiograph
  • Radiographic table

Always ensure the room dimensions are approximately 16 meters squared. But if the room is to host unique procedures, then consider it on the individual basis of its purpose and requirements. Lastly, we recommend doors have 1.5 meters of clearing access unless you install sliding doors.

X-ray Room Requirements to Consider

After designing the room by the relative dimensions, it’s crucial to supply each component of the X-ray room with the specific requirements.

X-ray Room Doors

X-ray room doors should be lead-lined with BS EN 12588 standards. In keeping with these standards, the doors will contain a certain thickness of lead, this level will vary dependent upon the application. The higher the dosage of radiation the thicker the lead.

Raybloc manufactures bespoke X-ray protective lead-lined door sets. Our doors are constructed to the latest hygiene regulations (NHS HTM 58) in infection control and are suitable for use across medical, veterinary, and radioactive environments. Our lead lined doors are fire tested to both FD30 and FD60 regulations, this includes our PVC encapsulated/postformed doors and flush mounted warning lights. Custom features can be included with exact dimensions while maintaining the doors meet the existing interior.

X-ray Room Walls

The level of protection required in the walls is determined by an RPA and will differ dependent upon the usage of the room. For example, dental X-rays rooms will generally use Code 3 lead where as a CT room could be between Code 5 – 7. For applications which require over 9mm of lead we construct these walls using lead chevron bricks.

If you’re unable to afford lead-lining within all aspects of the room protection, the recommended concrete equivalent is between four and six inches of thickness. Raybloc offers lead-lined panels, including 12.5mm lead-backed plasterboard, plywood and MDF.

The standard sizes for our lead-lined panels include:

  • 2400 x 600
  • 1200 x 600

However, custom sizes and thicknesses are available on request.

X-ray Windows/Operator Screens

The vital window is the protective window screen within between control room and the imaging room. It must be large enough for radiographers to have sight of the patient and machinery during procedures. We can provide an X-Ray Protective Viewing Window, specially designed to shield radiation with leaded glass and built to NHS HTM standards. It’s the ideal solution for control rooms.

We also recommend shielding glass made from radiation glass solution with 1.8mm to 3.5mm thickness. Our leaded radiation shielding glass can be layered to specific lead equivalence. All our products can be manufactured and designed on-site and customised to your preferred specifications.

We also offer a Fixed Operator X-Ray Screen with protective leaded glass and laminated bottom panels . All our X-ray screens are approved by RPA (Radiation Protection Advisors) and will be fitted to precision by professionally trained Raybloc carpenters.

Contact an industry leader in X-Ray room design and requirements

Since 2002, Raybloc has been working with architects to design and build radiation departments. Getting the design right is the first and all-important stage of ensuring X-ray rooms stay safe and operate effectively.

Architects must account for the ideal lead-lined specifications when designing X-ray rooms, CT rooms and industrial radiation areas. Key considerations involve size limitations, materials, RPA regulations and safe lead coverage methods.

So, if you’re designing an X-ray room, get in touch with Raybloc. One of our specialist advisors will ensure you make the correct investments and meet regulations.
