Protective device for shielding radiation

The invention provides a radiation shielding protective device which comprises a protective garment, a protective helmet is arranged on the protective garment, an opening and closing mask is rotatably mounted on the protective helmet, a refrigeration strip is arranged on the inner side of the protective garment, a heat insulation layer is mounted on the inner side of the refrigeration strip, and a mounting frame is mounted on the back of the protective garment. A storage bottle is mounted on the mounting frame, the refrigeration assembly is connected to the end part of the storage bottle, and the refrigeration assembly is used for cooling the protective clothing; by arranging the refrigerating assembly and the gas gathering assembly, the temperature of liquid nitrogen cold air is neutralized, the cooling comfort degree is improved, and the protective clothing is refrigerated and cooled, so that a human body can have a better rest through cooling, the burden caused by working in a closed high-temperature envir
