Gamma rays cause water molecules to produce free radicals through ionization, and these free radicals can seize the hydrogen on the macromolecular chain, so that the macromolecular chain cross-linked to form a three-dimensional network structure
穿透力强,可以穿透物质并深入样品内部,辐射效率高
Strong penetration, can penetrate the material and deep inside the sample, high radiation efficiency
