1. A neutron ray generating apparatus comprising:
an accelerator that emits a particle beam;
a target disposition portion that disposes a target that is irradiated with the particle beam to generate a neutron ray;
a transport path that transports the particle beam between the accelerator and the target disposition portion;
a first shield member that shields radiation; and
a second shield member that shields radiation, the second shield member being disposed to be spaced apart from the first shield member toward a side of the accelerator,
wherein the accelerator and the target disposition portion are disposed on a reference line of the transport path, and
the first shield member and the second shield member are provided between the accelerator and the target disposition portion.
