Abstract
A neutron ray generating apparatus includes: 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; and a transport path that transports the particle beam between the accelerator and the target disposition portion. The target disposition portion and the accelerator are disposed on a reference line of the transport path. A first shield member that shields radiation and a second shield member that shields the radiation and that is disposed to be spaced apart from the first shield member toward an accelerator side are provided between the target disposition portion and the accelerator.
