Features Include:

  • A “zero background” feature allows users to configure system background count time for 30, 60 or 100 seconds. This feature changes the counting time when selecting the “zero background” button in all functions, including the Moly Assay application.
  • Isotope libraries in both the dose calibrator and wipe test counter include Lu-177 and
    Ra-223 isotopes. Libraries include updated dial values, isotope ROIs and efficiency settings.
  • Half-Life Verification App included in the nuclear pharmacy menu. Simply select the isotope, choose two or three readings for the calculation, and set the time between readings. The results show the calculated half-life and the variance to the real half-life for the selected isotope.
