贫铀弹的放射性作用于生物体后 ,会出现核辐射生物效应。生物体 (主要是人、动物和植物 )吸收核辐射的能量后 ,会使细胞内物质的分子和原子发生电离和激发 ,进而导致体内高分子物质 (如蛋白质和核酸等 )分子键断裂而破坏 ;还会使生物机体内水分子电离成自由基 ,它与细胞内其他 After the radioactivity of depleted uranium shells acts on the living organism, the biological effects of nuclear radiation will appear. After absorbing the energy of nuclear radiation, organisms (mainly humans, animals and plants) ionize and excite the molecules and atoms of the substances in the cells, which in turn leads to the rupture of the bonds of the molecules in the body such as proteins and nucleic acids ; Will also make the biological body ionization of water molecules into free radicals, it and other intracellular
