Radiation Measurements and Dosimetry
This standard is issued under the fixed designation E170; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision.Anumber in parentheses indicates the year of last reapproval.A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This terminology generally covers terms that apply to radiation measurements and dosimetry
associatedwithenergydepositionandradiationeffects,ordamage,inmaterialscausedbyinteractions
by high-energy radiation fields. The common radiation fields considered are X-rays, gamma rays,
electrons, alpha particles, neutrons, and mixtures of these fields. This treatment is not intended to be
exhaustive but reflects special and common terms used in technology and applications of interest to
CommitteeE10,asforexample,inareasofradiationeffectsoncomponentsofnuclearpowerreactors,
radiation hardness testing of electronics, and radiation processing of materials.
