FUNCTIONAL DESCRIPTION
The activity of the sample will be displayed with a proper unit when a sample of unknown
strength (activity) of a known radioisotope is placed in the Well Counter and the correct
efficiency is input or measured.
With its NaI drilled-well crystal detector, the Well Counter offers greater sensitivity and faster
results than other wipe test monitors that use Geiger-Mueller (GM) tubes.
The microprocessor-controlled CAPRAC®-t has an automatic internal energy calibration
feature, which permits self-calibration of the keV per channel ratio.
For isotopes that have a measured efficiency, the CAPRAC®-t will convert readings in cpm
[counts per minute] to dpm [disintegrations per minute]. Most federal and state regulations
require survey monitoring results in dpm.
The CAPRAC®-t contains gamma spectroscopy data for 76 nuclides and efficiencies for 11
nuclides. Reference the Appendix for a complete listing of the nuclides included in the
CAPRAC®-t’s memory.
Note: The CAPRAC®-t Well Counter is not designed to provide conclusive identification of
radionuclides in samples. The CAPRAC®-t Well Counter is designed to provide the

first step for users who need to identify contaminants by narrowing down the
possibilities of which isotopes are contained in wipe test samples.
The CAPRAC®-t also provides a “Full Spectrum Efficiency” result for a wipe sample by
grouping all 256 channels together as one open-energy window. This indicates whether a
sample exceeds trigger levels, but does not help identify the contaminant.
