Neutron Doors and Frames are an important part of radiation shielding for Linear Accelerator Vaults. These doors are supplied with heavy duty weld on or bolt on hinges. Sliding Direct Shield Doors with a support framework are also available when the protective concrete maze is not practical.

Heavy weight doors can be manufactured with a removeable faceplate. This allows the door to be safely hoisted into position weighing less than 50% of it’s final weight. After installation, the door can be field loaded with the required amount of lead and borated polyethylene.

When a larger then normal clear opening is required, two doors can be mounted together with a lead lined astrigal to meet shielding requirements. The doors are operated by two automatic openers that can work in unison or independently.
