This article uses the Monte Carlo method and MCNP5 software to first simulate\nthe X-ray energy spectrum of the tungsten target and the silver target. On\nthis basis, using lead, tungsten and tungsten alloys (90% tungsten, 7.1% nickel,\nand iron 2.9%) as an X-ray shielding material, the shielding efficiency of\nthese three materials at different thicknesses is calculated, and the results\nshow that tungsten and tungsten alloy have better shielding effect than lead.\nFor the X-rays of different energies generated by the tungsten target and the\nsilver target, in order to achieve the same shielding effect, the X-rays generated\nby the tungsten target require a thicker shielding material.
