Furthermore, the invention has strong practicability and good use effect.
It should be emphasized that, in practical implementation, the length of the radioactive particle inlet 1033 is slightly larger than that of the radioactive particles 2000, and a radioactive particle transit groove 106 having a volume size matched with that of the radioactive particles 2000 is opened in the radioactive particle storage apparatus 10 at the upper part of the radioactive particle inlet 1033;
