Screening cover covers above the cavity of first shield;
Handle comprises the first handle that is separately positioned on first shield and the second handle on the secondary shielding body; And
Handle is used for connecting and shifting radioactive source.
Further, be provided with the orienting sleeve of hollow in first shield.
Further, the orienting sleeve inwall is provided with the gathering sill that is parallel to the orienting sleeve axis.
Further, the orienting sleeve upper surface is provided with the location cotter way.
Further, the orienting sleeve upper end is provided with the limited block of hollow.
Further, limited block is provided with breach in the face of gathering sill to the register pin groove location.
Further, radioactive source upper end and handle lower end are provided with interconnective screw thread.
Further, the radioactive source upper side is provided with register pin.
The utlity model has following beneficial effect:
The radioactive source screening device that the utility model provides; In the radioactive source transfer process, can arrive the radioactive source working position from the secondary shielding body with first shield; After radioactive source arrives the working position; Place first shield in the secondary shielding body, this is shielded radioactive source whole process in transfer process again, has reduced the radiant quantity that operating personnel accept radioactive source.
Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.To do further detailed explanation to the utility model with reference to figure below.
