Standard Practices for the
Measurement of Radioactivity1

This standard is issued under the fixed designation D 3648; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 These practices cover a review of the accepted counting
practises currently used in radiochemical analyses. The practices are divided into four sections:
Section
General Information 6 to 11
Alpha Counting 12 to 22
Beta Counting 23 to 33
Gamma Counting 34 to 41

1.2 The general information sections contain information
applicable to all types of radioactive measurements, while each
of the other sections is specific for a particular type of
radiation.

1.3 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
