[QUOTE="Benlaww, post: 6463665, member: 684842"] [B]Homework Statement:[/B] Using a simplified decay scheme for the generator (shown in attempt of solution box) and assuming that initially only 99Mo is present, the number of 99Tc atoms N_Tc as a function of time t is given by: N_Tc(t) = (landa_Mo/(landa_Tc - landa_Mo))*N_Mo(0)*(e^(-landa_Mo*t) - e^(-landa_Tc*t)) Calculate the minimum activity of 99Mo required to produce 20 MBq of 99Tc at t = 6 hours. State clearly any assumptions you make [B]Relevant Equations:[/B] A=landa*N [ATTACH type="full"]278985[/ATTACH]I'm not too sure where to start, do I differentiate the equation? [/QUOTE]
