Beschreibung
Zusammenfassung:	A neutron shielded door has a hollow interior portion for containing a neutron retarding fluid. This neutron retarding fluid may consist of hydrogen rich compound, such as water, with a dissolved boron compound. This door contains internal baffles for preventing surging of the neutron retarding fluid when the door is opened and closed. The neutron shielded door is contemplated for use with radiation therapy rooms housing medical accelerators and other equipment which generate low levels of neutrons. Ports are provided for the input and drainage of neutron retarding fluid from the door and fluid indicators are provided for permitting determination of the amount of fluid contained in the door.
