The application discloses neutron garbage bin and prevent combined material of neutron radiation. The utility model provides a neutron garbage bin, including the heavy nucleus material bucket that the one end open -ended has barrel -shaped cavity structure, neutron absorbed layer, steel layer and light element layer have been laid according to the preface in the bottom of heavy nucleus material bucket, heavy nucleus material bucket adopts lead, tungsten or depleted uranium preparation, the neutron absorbed layer adopts boron, lithium or gadolinium, the perhaps preparation of compound of boron, lithium or gadolinium, the instruction preparation in polyethylene, water or the paraffin is adopted on the light element layer. The utility model provides a neutron garbage bin and combined material can effectually block the neutron line to design light element layer, steel layer and neutron absorbed layer in heavy nucleus material bucket utilize the interact of each layer, have improved the neutron assimilation effect, and under the same assimilation effect, the effectual volume that reduces the neutron garbage bin is installed and use under the various space condition in order to make things convenient for it.
