Question

$\text{Ac}^{227}$ has a half-life of 22 years with respect to radioactive decay. The decay follows two parallel paths, one leading the $\text{Th}^{227}$ and the other leading to $\text{Fr}^{223}$. The percentage yields of these two daughter nuclides are 2 % and 98 %, respectively. The only incorrect information related with the decay is
