Radiation characteristics analysis for spallation products of lead-bismuth target and tungsten-iron-nickel target.

The radiation characteristics of spallation products are important references for evaluating the materials used as spallation targets. Therefore, it is necessary to study the radiation characteristics of spallation products. In this study, the spallation products of tungsten-iron-nickel target and lead-bismuth target were calculated and analyzed based on the radionuclide distributions and decay photon shielding of the spallation products.
