Linear Accelerator Direct Shielded Doors - An Approach for Calculating the Specialized Shielding Required Adjacent to the Door

摘要

Medical linear accelerator vaults occupy less space when constructed with a direct shielded door instead of a maze. The door is a secondary barrier, with a straightforward shielding calculation required to determine the required material. However, because of the limited overlap between the door and the entrance, additional specialized shielding is required next to the door. This paper describes an approach to determine the amount of specialized shielding required.
