[0002] The radioactive waste shielding device is a radioactive source lead barrel, referred to as a lead barrel, which is a radiation protection device made of lead plates. There are mobile lead barrels, combined lead boxes and other types of radioactive waste storage lead boxes. The radioactive waste storage lead boxes have radiation safety protection performance for storing radioactive materials. Most radioactive solid waste barrels used in radioactive workplaces are portable and have only one barrel lid. Since waste barrels generally use metallic lead as shielding material and the density of lead is relatively large, workers need to open the waste barrel lid with both hands before putting waste into the waste barrel. This operation is not only laborious but also easy to cause cross contamination and generate secondary waste. For this reason, we proposed a radioactive solid waste shielding device.
