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.

X-RAY GLASS SHIPMENTS AND DELIVERIES
X-Ray Glass is a very sensitive and fragile product and Ray-Bar understands the impact that receiving a broken shipment causes to the customer in both project schedule and as a double-loss expense. Manufacturing this specialty product correctly to our customers request is only half of our service; making every reasonable effort to ensure the product arrives to its destination in perfect condition is also paramount. Our customers can be confident that we take all reasonable protective measures and precautions. Our main priority is that you receive our products in good condition which is equally as important to us as it is to you. This is why our 65 years of experience in manufacturing,handling,packaging and successfully shipping our products nationwide and worldwide reaching their destinations promptly and intact as expected is so essential. Although we have no hands-on control of the product once loaded into the truck or container, we make every reasonable effort to safely package your product in its custom protective crate for transit. We use only established, responsible carriers with modern GPS location logistics and/or computerized freight tracing and tracking capabilities. Each piece of Ray-Bar X-Ray Glass is carefully inspected by our experienced QA department during fabrication and while hand setting the glass vertically into the custom built foam filled upright "A-frame" wood crates.All packaging shipments have proper handling / receiving instructions and proper warnings easily visible on the outside. All crates additionally have damage/mishandling indicators securely fastened to the outside to visually assist our customers and end-users in determining if the product has been dropped,damaged,mishandled or adversely impacted during transit. Our successful efforts to ensure our products safe delivery is obvious in our existing (yet thankfully rarely necessary) replacement claims policy of no additional product or frieght cost to our customer as long as shipping is by our choice of transport carrier, receiving procedures were performed exactly per Ray-Bar detailed directions to preserve frieght claim rights (such as customer carefully inspecting glass upon receipt in the presence of the delivery service and noting any issues clearly on the bill-of-lading receipt, keeping crate and product in original condition for claim adjusters inspection and immediate same day written notification to Ray-Bar). The replacement glass is of the exact same size, type, quantity and characteristics of the original damaged piece(s). Ray-Bar's standard 1-year product warranty provisions are issued to each x-ray glass product order. Exactly this type of customer service is another prime example why our established and repeat customers truly value the entire Ray-Bar experience.
