[QUOTE="BvU, post: 5614241, member: 499340"] Hello Smigglet, :welcome: If the original activity is given as 60 mCi it will be hard to give an answer in 4 digits. 1% is a reasonable estimate of the error in original activity. And the uncertainty in time is 6 months. Apply the error propagation rule $$\left (\Delta f(x,y) \right )^2 = \left ( \partial f\over \partial x\right )^2 \left (\Delta x\right )^2 + \left ( \partial f\over \partial y\right )^2 \left (\Delta y\right )^2$$ And PF greetings to your friend [/QUOTE]
