ABSTRACT:
A radiation shielding wood or laminate faced door having a high fire rating and method for making same are disclosed. The radiation shielding door comprises a non-combustible core having a first face, a second face. A supporting material is in contact with the non-combustible core. A first radiation shield is in contact with the first face of the non-combustible core. An intumescent material is in contact with the supporting material. The method of manufacturing a radiation shielding door includes the steps of providing an non-combustible core having a first face, a second face; securing a supporting material to the non-combustible core; adhering a first radiation shield to the first face of the non-combustible core; and providing an intumescent material to the supporting material.
