Description

Technical Field

[0001] The utility model relates to the technical field of protective doors, in particular to a proton irradiation heavy-load protective door assembly. Background Art

[0002] Protons, as positively charged particles, enter the human body at a very high speed. Due to their high speed, the chance of interacting with normal tissues or cells in the body is extremely low. When they reach the specific part of the cancer cell, their speed suddenly decreases and stops, releasing the maximum energy, generating the Bragg peak, killing the cancer cells, and effectively protecting normal tissues. Because proton therapy has the characteristics of strong penetration, good dose distribution, high local dose, less side scatter, and small penumbra, it shows great superiority, especially for the treatment of tumors surrounded by important tissues and organs. Proton therapy has a wide range of indications, and has good therapeutic effects on benign and malignant brain tumors, spinal cord tumors, cerebrovascular diseases, head and neck tumors, eye lesions, chest and abdominal tumors, pediatric tumors, and other diseases.

[0003] The existing shielding door of the proton irradiation room is relatively simple in design, and the shielding effect of the irradiation room is not ideal. In addition, its sealing performance is poor, and protons are easy to escape during use, affecting the use effect. Utility Model Content
