Radiation-shielding movable barrier

A radiation shielding assembly for a passageway in a radiation therapy facility, the radiation shielding assembly comprising:

• a first member arranged within a passageway and movable between an open position in which the passageway defines an opening, and a closed position in which the passageway is closed, the first member comprises a front face, a rear face, a trailing face, and a leading face including a sine-wave shaped leading edge, the first member has a core constructed of high-density or high-Z material having radiation-shielding characteristics;
• wherein radiation is at least one of high energy X radiation, neutron radiation, photon radiation, proton radiation, X ray radiation, gamma radiation, or high energy radiation;
• and
• a second member having a sine-wave shaped edge that is complementary to the sine-wave shaped leading edge of the first member, the second member having a core constructed of high-density or high-Z material having radiation-shielding characteristics, wherein when the first member is in the closed position, the sine-wave shaped leading edge of the first member and the sine-weave shaped edge of the second member interlock to form a tight seal between the first member and the second member to prevent leakage of radiation through the seal.

A radiation therapy facility comprising:

• a plurality of radiation shielding barriers defining a room;
• an opening defined in at least one of the radiation shielding barriers;
• and
• a movable barrier arranged within the opening comprising:
• a first member movable between an open position, and a closed position, the first member comprises a front face, a rear face, a trailing face, and a leading face including a sine-wave shaped leading edge, the first member has a core constructed of high-density or high-Z material having radiation-shielding characteristics;
• wherein radiation is at least one of high energy X radiation, neutron radiation, photon radiation, proton radiation, X ray radiation, gamma radiation, or high energy radiation;
• and
• a second member comprising a sine-wave shaped edge that is complementary to the sine-wave shaped leading edge of the first member, the second member having a core constructed of high-density or high-Z material having radiation-shielding characteristics, wherein when the first member is in the closed position, the sine-wave shaped leading edge of the first member and the sine-weave shaped edge of the second member interlock to form a tight seal between the first member and the second member to prevent leakage of radiation through the seal.
