Standard Terminology Relating to Nuclear Materials
SCOPE
1.1 This terminology standard contains terms, definitions, descriptions of terms, nomenclature, and explanations of acronyms and symbols specifically associated with standards under the jurisdiction of Committee C26 on Nuclear Fuel Cycle. This terminology may also be applicable to documents not under the jurisdiction of Committee C26, in which case this terminology may be referenced in those documents.

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.

activity, A, [T ], n—the measure of the rate of spontaneous nuclear transformations of a radioactive material. The SI unit for
activity is the becquerel (Bq), defined as one transformation per second. The original unit for activity was the curie (Ci), defined

as 3.7 3 10 transformations per second.
alpha radiation, n—is the spontaneous emission of an alpha particle, composed of two protons and two neutrons with a positive
charge of plus two, during the nuclear transformation process.

dose equivalent, [L T ], n—a measure of the biological effects of radiation dose from all types of radiation expressed on a
common scale.
DISCUSSION—The SI unit for dose equivalent is the sievert (Sv), which is equal to 100 rem (specialized unit for human dose equivalent). Radiation
dose equivalent is often expressed in terms of microsieverts (µSv) or millirem (mrem).
