This utility model discloses a neutron analysis device, relating to the field of radiation detection equipment technology. The neutron analysis device includes a support frame and a detection device and a radiation source mounted on the support frame. A channel is formed between the detection device and the radiation source along a first direction. The detection device includes a first shielding module and a detector. The first shielding module has a first shielding cavity extending along a second direction on one side facing the channel, and the detector is located in the first shielding cavity. The radiation source includes a second shielding module and a neutron generator. The second shielding module has a second shielding cavity extending along a second direction on one side facing the channel, and the neutron generator is located in the second shielding cavity and is positioned opposite to the detector. The thickness of the first shielding module decreases from the middle of the detector to both sides in the first direction. The second direction intersects the first direction. This arrangement can significantly reduce the amount of shielding material used, thereby significantly reducing the volume and weight of the neutron analysis device.
