H-201 - Health Physics Technology - Slide 22 - Recall that A(t) = A0 e-λt and in this case, the half-life of F-18 is ~ 110 minutes, so A(t) = A0 e-λt = 106 atoms * e -.693/110 min * 220 min = 2.5E5 atoms
The rules of radioactive decay may be used to convert activity to an actual number of atoms. They state that 1 Ci of radioactive atoms would follow the expression N (atoms) × λ (s −1) = 1 Ci = 3.7 × 10 10 Bq, and so N = 3.7 × 10 10 Bq / λ, where λ is the decay constant in s −1. Here are some examples, ordered by half … See more The curie (symbol Ci) is a non-SI unit of radioactivity originally defined in 1910.
