Scope

This Standard specifies the quantitative technique for the determination of
radionuclides’ activity using various ionization chambers that are currently available.
The application of this Standard is limited to instruments that contain well-type
ionization chambers as detectors. It is a composite system that includes an ionization
chamber and an appropriate circuit in overall connection to it that converts the current
in the ionization chamber into a reading in the unit of activity.
This Standard provides methods to obtain measurement whose accuracy does not
exceed ± 6% and whose repeatability is not more than 2% (generally for radionuclides
larger than 3.7  106 Bq (100 μCi)).
