Description

Technical Field

[0001] The utility model relates to the field of sliding doors, in particular to a medical radiation leakage-proof sliding door. Background Art

[0002] According to GB18871-2002 "Basic Standard for Ionizing Radiation Protection and Radiation Source Safety", the indoor walls, wall ceilings, doors, windows, vents, etc. of exposure rooms with medical radiation and industrial equipment can be effectively protected. However, the radiation leakage caused by the gap at the bottom of the mobile protective door of the exposure room cannot be effectively protected. This is mainly because the protection will affect the opening of the door and the patient operating cart entering and leaving the exposure room will be bumpy due to the uneven ground or protective devices. For many years, most of the gaps at the bottom of mobile protective doors in my country's radiation protection field have been in an unprotected state.
