Embodiment 1
[0030] A fission for irradiation production 99 Low-enriched uranium uranium foil target of Mo, the target has a "sandwich" structure, such as Figure 7 As shown, it includes an inner target tube 15, an outer target tube 17 and a uranium foil 16; the uranium foil 16 is located between the inner target tube and the outer target tube;
[0031] The inner diameter of the inner target cylinder 15 is constant, and the outer wall is designed as a tapered structure with a taper of 1:160;
[0032] The uranium foil is wrapped on the outside of the inner target tube, the thickness of the uranium foil is 150 μm, and the inner and outer surfaces of the uranium foil are coated with a fission recoil protective layer, and the thickness of the protective layer is 15 μm;
[0033] The outer diameter of the outer target tube is constant, the inner wall is designed as a tapered structure, and the inner diameter and inner wall taper of the outer target tube are respectively adapted to the outer dia...
Embodiment 2
[0048] The difference from Example 1 is that the material of the inner target tube and the outer target tube is Mg, the thickness of the uranium foil is 120 μm, and the thickness of the fission recoil protection layer is 18 μm.
Embodiment 3
[0050] The difference from Example 1 is that the material of the inner target cylinder and the outer target cylinder is Zr, and the thickness of the fission recoil protection layer is 12 μm.
