title: Frequency of occurrence of various nuclear reactions when fast neutrons (approximately less than 50 MeV) pass through tissue-equivalent material.
abstract: Calculated results are presented for the frequency with which various partial nuclear reaction cross sections are utilized when fast neutrons (approximately less than 50 MeV) are transported through a tissue-equivalent phantom to obtain an indication of which cross sections are of most importance for radiotherapy applications and are therefore in need of experimental verification.
