that's right. For the case of a Mo-99 and Tc-99m generator, at t=0, let the activity of Tc-99m be zero. The activity of Tc99m will increase until it reaches a maximum value, but will then start to decline as per transient equilibrium. I think using the bateman equations you can derive an...

Hi, I'm having a bit of difficulty deriving the time to max activity for the case of transient equilibrium for a parent-daughter. This is where I want to get to , tm = (1 / (λ1-λ2)) * 1n(λ1/λ2) I believe there is an alternative equation for tm as well expressed in terms of half-life...
