## Homework Statement

A source having a half life of 5.27 years is calibrated and found to have an activity of 3.5*10^5 Bq.The uncertainty in the calibration is +- 2%

Calculate the length of time in days after the calibration has been made for the stated activity to have a maximum possible error of 10%

## Homework Equations

[tex]A=A_oe^{-\omega t} [/tex]

[tex]t_{1/2} = \frac{ln2}{\omega} [/tex]

## The Attempt at a Solution

I can't find a possible correlation between the uncertainty and activity.
