The half life of the radioactive element Strontium-90 is 37 years. In 1950, 15 kilograms of this element released accidentally. How do you determine the formula which shows the mass remaining after t years?
Note: The half life of Strontium-90 is now published as 28.8 years. This will require adjustments of all the following values in
The formula for the half life of an exponentially decaying substance is:
To calculate the mass of Strontium-90 remaining after
In 2017 (now) the amount left is
