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. A number 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

radiation hardness testing of electronics, and radiation processing of materials.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

This standard is issued under the fixed designation E170; the number immediately following the designation indicates the year of

INTRODUCTION
This terminology generally covers terms that apply to radiation measurements and dosimetry
associated with energy deposition and radiation effects, or damage, in materials caused by interactions
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
Committee E10, as for example, in areas of radiation effects on components of nuclear power reactors,
radiation hardness testing of electronics, and radiation processing of materials.
This terminology uses recommended definitions and concepts of quantities, with units, for radiation
measurements as contained in the International Commission on Radiation Units and Measurements
2
(ICRU) Report 85a on “Fundamental Quantities and Units for Ionizing Radiation,” October 2011
Those terms that are defined essentially according to the terminology of ICRU Report 85a will be
followed by ICRU in parentheses. It should also be noted that the units for quantities used are the latest
adopted according to the International System of Units (SI) which are contained in Appendix X1 as
2
taken from a table in ICRU Report 85a. This terminology also uses recommended definitions of two
3
ISO documents , namely “International Vocabulary of Basic and General Terms in Metrology.” (VIM,
2008) and “Guide to the Expression of Uncertainty in Measurement” (GUM, 1995). Those terms that
are defined essentially according to the terminology of these documents will be followed by either
VIM or GUM in parentheses.
A term is boldfaced when it is defined in this standard. For some terms, text in italics is used just
before the definition to limit its field of application, for example, see activity.
