Gamma Knife Rooms

Gamma Knife rooms primarily utilize 201 sources of the very high energy isotope Cobalt-60, located in a shielded "helmet" set in place over the patient's head to treat head cancers and brain tumors. This technology is utilized primarily in Radiation Therapy or Oncology Centers. Contact Ray-Bar today to discuss your Gamma Knife room requirements and request a customized radiation shielding solution.

Gamma Knife Room Dimensions

Room sizes vary from 20'0" x 20'0" to approximately 24'0" x 24'0". These rooms require heavily specialized shielding design due to the extreme energy levels involved, including a ceiling vault and a heavily shielded door assembly. Shielding must be calculated by a certified and licensed radiation or health physicist or other "Radiation Expert" (as defined by NCRP or ICRP) and independently retained by the radiation therapy or oncology facility.

Gamma Radiation Shielding Requirements are Generally Based on These Factors:

• Specific Gamma Knife treatment system model and type utilized
• Beam geometry and orientation in room in relation to surrounding walls
• Projected use — treatments / procedures per day / workload
• Surrounding occupancy factors / common walls
• High-density concrete wall thickness (often several feet)
• Ceiling vault construction — steel, lead brick, or lead plate
• Long-term exposure control requirements
• Controlled vs. uncontrolled (monitored by dosimetry, general access)

Ray-Bar Has Several Products and Materials to Meet Your Radiation Shielding Requirements

Shielding for Gamma Knife rooms typically involves high-density concrete walls (often several feet thick), a ceiling vault constructed of steel, lead brick, or lead plate, and a heavily shielded door assembly. Ray-Bar offers Lead Lined Doors and specialty lead shielding products including lead sheet, plate, and brick and powder coated lead for vault construction. Lead vinyl flexible shielding is also available for specialty or supplemental shielding applications. Because of the extreme energy levels involved, shielding design is highly specialized and must account for beam geometry, workload, occupancy, and long-term exposure control.
