The invention purpose a so while minimizing the radiation exposure of the operator by so shielding the moving shield and separated by a fixed shielding element moves with the Cf-252 neutron source move while moving shield the neutron source capsule to the neutron irradiation test or index test It relates to a handling device of the neutron source.; Neutron source handling apparatus of the present invention, the mounting hole 11 is embedded in the center and a plurality of irradiation holes 13 a through the side of the fixed shielding element (3), is detachably inserted into the mounting hole 11, which movement that is adapted to store the prior capsule (7) within the shaft hole 15, the shield (5), said mobile bar (17) of the crew capsule coupled to one end that is inserted into the shaft hole 15 (7), and said moving bar the insertion hole (19) (17) is inserted is formed, and is characterized in that it is composed of a shielding cover (9) fitted in the mounting hole 11 of the fixed shielding element (3).; Therefore, according to the present invention, exposure of the operator is very little, and the handling is very easy, it is possible to advantageously carried out while the safety neutron irradiation experiments or index experiments.
