Radiation protection method for MOX pellet preparation process

The invention belongs to the technical field of nuclear chemical radiation protection and in particular relates to a radiation protection method for an MOX pellet preparation process. Key equipment ona production line is enclosed by using glove boxes; the whole production line is formed by sequentially connecting a plurality of glove boxes; radioactive aerosol is used as an atmosphere in each glove box; each glove box is matched with an independent mechanical pump; the front end of the mechanical pump is designed to be provided with a filter-cloth-type efficient dust filter; the mechanical pump has the effect of making the average pressure inside each glove box smaller than the normal atmosphere pressure 300kPa; the glove box with the highest radiation level is placed in the middle of theproduction line; the radiation level of the glove box closer to the outer side is lower; the pressure of the glove box with a higher radiation level is lower; the pressure difference of the adjacentglove boxes is 20kPa; a sea
