1 Radioactive decay Consider a chain of radioactive decays 1 -+ 2 -+ 3, where nuclei of type 3 are stable. We assume that we begin with No atoms of the parents at t = 0 and no atoms of the decay products are originally present. The decays constants are represented by A1, 12. a) Compute Ni(t) b) Compute Na(t) c) Compute Na(!) d) Compute Ni(t) + Na(t) + Na(t) and interpret. e) Plot Ni(t), Na(t), and Na(t) approximately and interpret them at small t and t - co
