A Survey of Current Research and Developments in the Field of Dosimetry

Résumé du livre

A survey of current practices used in high-level dosimetry of gamma, neutron, and mixed fields is presented. Chemical and calorimetric systems including ferrous-ferric, ceric-cerous, gas evolution, nitrous oxide, various dyes, and polymers have been considered. Silver-activated phosphate and other gases are discussed. Ionization chambers for either gamma ray or neutron measurements have been commonly employed at very high dose rates and several designs are discussed. Luminors such as anthracene and napthalene, and semiconductors such as germanium have also found application at high radiation doses. Different designs of calorimeters have been used for measuring energy absorbed, but only to a limited extent. Neutron spectra ranging from thermal through resonance to fast neutrons can best be determined by activation of appropriate materials having desirable nuclear properties.
