The Dose Calibrator Program
From the Home screen, touch <Dose Calibrator> to access the Dose Calibrator Measure
screen. At this screen the system operates as a dose calibrator. A list of isotopes is
displayed along with time, date, detector #, measured activity, and Activity Units. The
measured activity is the real-time activity being measured in the detector for the first (most
left) isotope displayed.
The Dose Calibrator Measure screen activity reading defaults to the last selected isotope, or to
Tc-99m if no isotope has been previously selected. The system selects the most recently used
units of measure (mCi or Becquerels,) or defaults to mCi if units have not been previously
selected.
In addition to counting isotopes, the Dose Calibrator screen allows the user to <Zero
Background>, <Select Isotope>, perform <Dose Calculation>, or <Print Labels> for the current
activity in the detector. There are two types of labels that print.
