Libraries
Radionuclide information is stored and accessed in the Nuclide Library. The
Nuclide Library consists of the Quench Standards and Sample Nuclides Libraries.
If your instrument is equipped with an Alpha Beta option, an Alpha Beta
Standards and an Alpha Beta Nuclides Library will also be included.
The Quench Standards Library is comprised quench sets, with each quench set
containing individual quench standards. The data from the quench standards is
used to construct quench curves for calculating DPM (Disintegrations Per Minute)
in DPM Assays. Quench Standards are counted once and the entire spectrum for
each quench standard is stored independent of assay information. This allows you
to select and use the same quench set in any number of assays and construct a
quench curve for each sample at the time the sample is counted.
The Sample Nuclides Library allows you to specify and save nuclide names,
counting region limits and quench sets for sample nuclides. Up to three nuclides
can be defined for each entry to support the counting of multiple nuclides. These
sample nuclide parameters are typically specified as part of the assay definition
process and may be edited as needed.
The Alpha Beta Standards and Alpha Beta Nuclides Libraries are used in the same
manner as the Quench Standards and Sample Nuclides Libraries. The information
stored in these libraries is relevant only when performing Alpha Beta Assays,
where both an Alpha-emitting and a Beta-emitting radionuclide are quantified
independently within the same sample vial.
