DEFINITIONS AND ABBREVIATIONS

The definitions below come from many sources, indicated in the definition itself, and many have

been adopted from the compilation by (Traub 1994). In this section, RadCon Standard refers to the U.S.

Department of Energy Radiological Control Standard (DOE 1999e); 10 CFR 835 refers to the DOE rule

Occupational Radiation Protection (DOE 1998a); AMG refers to the DOE Air Monitoring Guide (DOE

1999d); and IDG refers to the DOE Internal Dosimetry Program Guide (DOE 1999b). Other definitions

come from other DOE documents, national and international standards and recommendations; some

definitions are new. Terms in italics are defined elsewhere in the definitions section.

2.1 DEFINITION CROSS-REFERENCE

Most of the terms commonly used in the field of internal dosimetry have been adequately defined

in documents that are commonly available at DOE sites and facilities. Rather than repeat the majority of

these definitions here, Table I cross-references these definitions to other documents. Where a definition

is found to have more than one source, the definition that occurs in 10 CFR 835 (when applicable) should

be taken as the official definition for that term. Definitions are given in Section 2.3, when they are not

given in 10 CFR 835, the RadCon Standard, IDG, or AMG, or when it is useful to present additional

clarifying information. In Table I below, italicized items are used as symbols for the quantity elsewhere

in this standard.
