RPP’s sliding radiation shielding doors
(neutron doors) are constructed with ¼" thick A-36 steel face plates. A-36
steel flat bars are used for the stiles and the reinforcement inside the door.
Flat bar thicknesses for the stiles and reinforcement are dictated by the core
of the door. The core of the door will consist of the shielding requirements
(typically lead and borated polyethylene) as determined by a licensed
physicist. We can also design the door with extra space inside for future
upgrades which may require more shielding. The neutron door finish is completed
in the factory with a paint grade primer. RPP offers safety features for the
door such as motion sensors, pressure sensitive tape, and battery backup.
I-Beams are used in
conjunction with trolleys that suspend the door. For new construction, concrete
embedments are used for support. For retro-fits, steel beams and steel columns
are used.
