Description

Technical Field

[0001] The invention relates to the technical field of decontamination beds, and in particular to a decontamination bed for cleaning radioactive pollutants. Background Art

[0002] Nuclear energy is energy released from the nucleus through nuclear reactions. It is a relatively clean energy source that humans can currently use. It is widely used in power generation, medical and military fields. However, nuclear energy also has major disadvantages. The first is that nuclear energy will produce highly radioactive nuclear waste during use. Although the volume is not large, it has strong radioactivity and will cause serious harm to the environment and humans if not treated.

[0003] In nuclear power plants and other nuclear energy equipment, nuclear leakage may occur due to improper operation or geological disasters. At this time, personnel are needed to carry out maintenance. Some dust containing radioactive elements will float around and adhere to the maintenance personnel. If it is not cleaned in time, it will cause great harm to the health of the maintenance personnel, and in serious cases, it will endanger the life safety of the maintenance personnel. At present, the more commonly used cleaning method is to clean in a decontamination tent or on a decontamination bed. The decontamination tent occupies a large area and needs to be temporarily set up, which is time-consuming. If the maintenance personnel are in a coma, they cannot enter the decontamination tent to clean by themselves. When cleaning with a decontamination bed, it is generally cleaned with the cooperation of medical staff. During the cleaning process, decontamination water is easy to splash on the medical staff, and the decontamination water contains radioactive substances. After splashing on the medical staff, it will also cause harm to the medical staff. In order to prevent the decontamination water from sticking to the medical staff, protective clothing (such as air clothing) needs to be worn, which affects the movement speed of the medical staff, and is not conducive to the sweating of medical staff in the hot summer, which is easy to cause heat stroke.
