comment Exponential decay and time constants
@StefG Thanks for the link! I'm just a little confused because their proof uses integration by parts and not $t = \tau$ to show that the mean lifetime or time constant is related to the decay rate: en.wikipedia.org/wiki/…

comment Modelling differential equations
Thanks. I think $r =\frac{r_0}{2}$, this gives me $\lambda = \frac{ln(2)}{5230}$. Also, if Iodine 131 has a half-life of 8 days, does that mean $t = \frac{8}{365}$?
