Radiation Dosimetry, Second Edition, Volume I: Fundamentals describes the significant aspects and fundamentals of radiation dosimetry. This books deals with the concepts and units of dosimetry; special problems of energy deposition in the microscopic domain; interactions of x and y rays, charged particles, and neutrons with matter; mathematical theory of radiation fields; ionization; and cavity-chamber theory. Other topics discussed include the LET distributions, Compton and photoelectric effect, pair production by photons, dosimetry principles, and interactions of neutrons with tissue elements. The calculation of neutron dose in large objects; ionization in gases, liquids, and solids; and cavity dimensions comparable with the electron ranges are also deliberated. This publication likewise covers the measurement of absorbed dose and exposure and application of cavity theory to devices other than the ionization chamber. This volume is a valuable reference for radiation workers, but is also beneficial to students and researchers interested in radiation dosimetry.
