Radioactive Decay Calculator
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.

I am a nuclear medicine technologist. I find this app useful. I can assay a dose at anytime and it will calculate the current activity. This is useful for the times we are waiting for the doctor in the stress room. I would like for you to add the ability to subtract a post injection syringe assay. That assay happens immediately after the injection so no further decay is needed.
Can't open on Pixel 2 running Android Pie.
not working xiaomi note 8
no Co-60 so this app does me no good
Will change to 5 stars if you could add an additional function to just use hours instead of a specific time. Also, if you could add a an input for desired activity at a certain time (in the future) and then it would give me the amount I need now, that would be awesome. I'm a nuclear pharmacist, and have to draw up doses that will be a certain activity at a future time.
The app doesn't remember entered values. Entering them again each time draws it kinda useless. Add this functionality and I'll give you five stars.
Really it helps me so much
Does exactly as it says on the tin
Too much headache. Should be easily operated but it's nice app
A simple to use app. Ideal for Nuclear Medicine Technologists.
Fab app. Will use this at work in Nuclear Medicine.
This seems like a pretty helpful reference, but could you guys just add a table of isotopes and half-lives? I get I could just go to the edit half-life page to see, but it would look more sleek with a simple table of them.
