Confusion It can be shown by straightforward substitution that the curves of parent and daughter activity cross at the exact time that the daughter activity is a maximum. [...] Parent Activity A1. Daughter Activity, A2. I. Fast Daughter, L2 = 10L1, T2 = T1/10 II. Slow Daughter, L2 = .5L1, T2 = 2T1 The first daughter, Th, will grow into secular equilibrium with the U within a matter of days. This is illustrated by the "fast-daughter" (type I) curve of problem 9. After a few days we may consider the Th activity equal to the U activity, and go on to consider how the Pa grows in.
