EFFICIENCIES DATA
Efficiency data are used to convert the observed counting rate to the activity value.
Efficiency is a measurement parameter that is defined as the ratio of detected counts (or
counting rate) measured by the system to actual disintegrations (rate of decay). Efficiency
can be defined as follows:
minuteper tionsdisintegra

The efficiency of a nuclide depends upon the geometry, region of interest, energy,
abundance and activity of the source as well as the type of detector system used to measure
the source. For these reasons, efficiency values vary from one nuclide to another.
