SIZING YOUR X-RAY VIEW WINDOWS
GENERAL: LEAD GLASS is used in medical in industrial applications so that the equipment operator can view pthe part or patient without being exposed to radiation. In most cases, the radiation attenuations of the glass must be at least equal to the wall in which the window is located. It is also recommended by the nuclear regulatory commission that a lead glass windows be at least 18" from the end of the operator control wall to insure the technician is fully protected.
MATERIAL: LEAD ACRYLIC is also available for all viewing applications and should be considered for large windows and mobile barriers to reduce breakage concerns.
HOW HIGH? Since all human eyes are 5" to 6" below the top of the head, an upper height of 6'8" above the floor will accommodate individuals '6'6" tall.
HOW LOW? A bottom height of 36" AF should accommodate all requirements.
STANDING * A bottom height of 54" will accommodate individuals 5'0" tall, therefore a windows 18" high will handle personnel 5'0" to 6'6" tall. Examples of STANDING include Chest Room, Radiographic, Tomographic and R.F.
SEATED / STANDING * with equipment at desk height of 30", a lower window height of 36" should be acceptable for nearly all persons. If consoles are located at the counter height of 40", the view window bottom should be raised so wiring is not seen from the exam room. Examples include C.T. Scan, Angiography, Remote R/F, Cardiac Cath, Special Procedures etc.
HOW WIDE? The view windows should not be wider than required for the operator and observers to comfortably view the patient and equipment associated with the exam. The width will vary with the type of exam room and the lateral area required to visualize all associated equipment.
