Customer must order frame to match same shielding value in wall/partition that window occurs in.

• SPECIAL OPTIONS

Bottom voice passage, 45 degree splayed faces (for wider view range), vertical center mullions, extra thick wall conditions, stainless steel construction (304 with #4 finish), security abuse resistant designs, special lead lining or lead glass requirements all available upon request.

• DIMENSIONS

Our standard leadlined telescopic frames are ordered by actual glass size and fit into rough opening of 1" larger than glass size to allow 1/2" clearance around perimeter of the frame. The OUTSIDE dimensions of our standard frame are 3" LARGER than glass size on X-Ray side and 4-1/4" LARGER than glass size on Control Side.
EXAMPLE: A 12" X 12" telescopic frame will fit into a rough opening of 13 " X 13 " and will have an outside dimension of 15" on X-Ray side and 16-1/4" outside dimension on Control Side.

• Dimensions vary for telescopic view window frames with special options.

X-Ray Lead Glass Production

• INSTALLATION

Separate two-piece modular telescopic view window frame and install Lead Lined/Lead Glass portion on X-Ray source side of rough opening. Install "Slip-Side" flange on control side of rough opening at same time and slide both pieces together tight to wall. Check to verify that frame is level and fasten with self-tapping pan head screws on flat flange portion to stop. Always screw through both halves of frame, 6" on center. (4 places minimum.)

MEDICAL X-RAY RADIOGRAPHIC DIAGNOSTIC IMAGING CONTROL VIEW WINDOW DESIGN REQUIREMENTS

NCRP #49 requires under Radiographic Installations 5.3.2 : "Provision shall be made for the operator to observe and communicate with the patient from a shielded position at the control panel.When an observation window is provided ,it shall have a lead equivalence at least equal to that required of the partition(or the door)in which it is located."

The current AIA and FGI Guidelines for Design and Construction of Health Care Facilities requires under Shielded Control Alcoves 5.5.4.4 : "Each x-ray room shall include a shielded control alcove. This area shall be provided with a view window designed to provide full view of the examination table and the patient at all times,including full view of the patient when the table is in the tilt position or the chest x-ray is in use."

NCRP #147 requires under Types of Medical X-Ray Imaging Facilities, Radiographic Installations 2.2.1 :"The control booth shall have a control window or viewing device that allows the operator to view the patient during all x-ray exposures performed in the room. The operator must be able to view the wall bucky and x-ray table,as well as patients confined to stretchers. When an observation window is used,the window and frame shall provide the necessary attenuation required to reduce the air kerma to the shielding design goal.The window(s) should be at least 45 x 45cm (18" x 18") and centered 1.5m (60") above the finished floor."

*Please Note the above uses of the word "shall" is a requirement, and use of the word "should" is a recommendation.

DOA Technical Manuel TM 5-805-12 and DOD Unified Facilities Criteria UFC 3-190-03A "X-Ray Shielding" both state: "Leaded Glass.The leaded glass is a clear lead glass sheet approximately 1/4" inch thick and is installed in single or multiple thicknesses to provide a lead equivalent not less than that of the partition or door of which it is a part of".

ICRP Publication#44 "Protection of the Patient in Radiation Therapy"(33): "There must be a means for observing the patient continuously during treatment. This may be accomplished by use of a lead-glass window,"

IAEA Chapter 16 "Radiation Protection and Safety in Radiotherapy" 16.10: "Adequate systems, devices or other means should be provided to allow operator to have a clear and full view of the patient.The systems for patient observation should be redundant and independent (e.g.closed circuit television or lead glass windows,depending on type of treatment unit)".

*Please Note these important considerations:
All television or electronic camera systems require skilled maintenance and service, and have the potential of failing, having picture loss and component problems. A X-Ray Lead Glass Control Window provides a continuous clear view of patient,equipment and room, and has no maintenance other than occasional cleaning.

ADDITIONAL SAFETY DESIGN CONSIDERATION

Per ANSI Z.97.1 and CPSC 16 CFR 1201 Category 2 standards, any x-ray control window occurring within 24" of a door opening,or any vision lite window occurring in a shielded door must have impact resistant X-Ray Safety Glass,and be permanently labeled as meeting these required impact resistant standards.

RAY-BAR LEAD LINED VISION LITE FRAMES are fabricated with 18 gauge cold-rolled steel with baked-on color finishes, mitred corners and internal lead lining to specified shielding requirements with x-ray safety glass permenently labeled meeting ANSI Z97.1 and CPSC 16 CFR 1201 CAT 2 for impact resistance requirements. Stock sizes 8x10, 10x10, 10x12, 12x12, 12x16, 16x16, 18x18, 18x24, 18x30, 18x36, 24x24, 24x30, 24x36 and 36x36 promptly available ready to ship. All other custom sizes typically available in 5 working days.
