Applications for Lead-Lined Sheetrock
Ray-Bar's lead-lined drywall provides superior radiation shielding in commercial, medical, municipal, and other demanding industrial environments nationwide. The lead layer laminated to the drywall's backside blocks X-rays and gamma rays, making it suitable for use in rooms and facilities that handle high-level radiation. Common applications for lead-lined sheetrock include:
- Hospitals
- Clinics
- Imaging Centers
- Radiation Therapy/Oncology
- Industrial X-Ray Rooms NDT
- Medical Schools
- University Medical Centers
- Cancer Centers
- Nuclear Applications
- CT Scanners
- Angiography / Cath Labs
- Radiology / Fluoroscopic / X-Ray
- Linear Accelerators / Simulators
- Tomo Therapy / Gamma Camera
- PET Scanners
- Uptake Injection Rooms
- Hot Labs
- Cyclotron
- Proton Beam Room
- Nuclear Medicine Rooms

Determining Shielding Requirements for Lead Lined Sheetrock
Shielding requirements should be determined by a qualified health radiation physicist. See Shielding Information for more information.
NCRP Construction Requirements
The current NCRP Report #147(2004)1.5 General Concepts, states:
"Radiation shielding shall be designed by a qualified expert to ensure the required degree of protection is achieved."
"The qualified expert should be consulted during the early planning stages since the shielding requirements may affect the choice of location of radiation facilities and type of building construction. The qualified expert should be provided with all pertinent information regarding the proposed radiation equipment and its use, type of building construction, and occupancy of nearby areas. It may be necessary to submit the final shielding drawings and specifications to pertinent regulatory agencies for review prior to construction."
"The term "qualified expert" used in this report is defined as a medical physicist or medical health physicist who is competent to design radiation shielding for medical x-ray imaging facilities. The qualified expert is a person who is certified by the American Board of Radiology, American Board of Health Physics, or the Canadian College of Physicists in Medicine".
*Please Note: the above use of the word "shall" indicates a requirement, and the word "should" indicates a recommendation.
*NCRP is the "National Council of Radiation Protection". *NCRP report #147 supersedes the previous NCRP report #49.
