[0002] With the development of nuclear energy and nuclear technology, nuclear industry, nuclear mining and nuclear medicine and many other fields have carried out nuclear technology application activities. The staff engaged in radioactive work often need to operate radioactive substances or equipment containing radioactive substances at close range. Although professional shielding devices are arranged in radioactive places to reduce the dose effect of radioactive substances on the staff, there are still some close-range operations that the staff need to perform, such as the staff giving animals injections during the radioactive drug experiment process, and the staff grinding valves at close range during the overhaul of nuclear power plants. Close contact with radioactive substances will result in a higher radiation dose rate of the hands receiving gamma or beta rays, and the existing protective articles do not have obvious radioactive protection effect on the hands, especially the finger parts, which will still receive a large dose of irradiation.
