Isotope:  
Half Life:  
Activity of Isotope :  
Date of Activity :
Decay Duration (Days):    

Information:

This calculator graphs the radioactive decay of a given isotope over a specified period of time using the formula:

N=Noe-(0.693t/T½)

Where:

N = Final activity
No = Initial activity
e = 2.71828183...
0.693 = radioactive decay constant
t = duration of decay
T½ = Isotope half life
This formula is then graphed as the following function:

y=Noe-(0.693x/T½)

As well as graphing this function, the calculator also returns a table of results (below) displaying elapsed days, the date and the activity of the isotope.

This calculator should be used for information only
