Radioactive Decay Calculator

A simple calculator to calculate decayed values for activities in either Becquerels or Curies.
Advanced features include multiple reference dates, an editable database of Isotopes with their half life constants and an exportable log file to easily record activities and transfer them off your phone.

Simply long-press the reference buttons to enter reference dates then enter an activity and use Ref1, Ref2 to show the activity decayed to that reference. Use the clock button to show the activity decayed to the current time.

An ad-supported free version is also available which has some minor limitations.

It takes time to adjust clock and date. .if I need the decay after 6 hours for certain F18 activity for example,I need to enter date and time that represents the 6 hours and this long process. ..While you can add an option to enter the isotope and the elapsed time (6 hours) directly.
