The Nucleon-Meson Cascade and Shielding

When a high-energy particle passes through matter, a nucleon-meson cascade develops

The designing of radiation shields for manned space vehicles and for high-energy accelerators requires a knowledge of the nucleon-meson cascade that develops when a high-energy particle enters matter. The accuracy with which calculations of the nucleon-meson cascade can be made is to a large extent determined by the available information on particle production from nuclear reactions. The accuracy with which an effective shield can be designed is also determined by the available information on the biological effects of radiation.
