A simple calculator to calculate radioactive decay for a variety of radionuclides. Activities may be entered in Bq or Ci and conversions between these units is possible within the app. Many common radionuclides especially those used in Nuclear Medicine and Positron Emission Tomography (PET) are predefined in the app. Users may add and save additional radionuclides and define the half-life.

The decay calculator allows the user to enter a radionuclide reference date and reference time. The current activity is displayed and updated for radioactive decay in real time. In addition a specified date and time can be entered and the decay corrected activity at this time will also be shown.

Users working in Nuclear Medicine departments and Radiopharmacy labs will find this decay calculator useful.
