6. Solve these calculations and place as an appendix in your assignment: a. Rearrange $A_t = A_0e^{-\lambda t}$ for $\lambda$ b. Using your generic formula for $\lambda$ from the above question, what is $\lambda$ for the following isotopes? a. $^{99m}Tc$ c. If you had 1000MBq of $^{99m}Tc$ @ 7am, what would the activity be at the following times? a. 8am b. 11:30am c. 2:15pm d. 4pm d. If you had 1000MBq of $^{99m}Tc$ @ 4pm, what would the activity have been at the following times? a. 6am b. 10:30am c. 12pm d. 2:15pm e. At 7:30am 23GBq of $^{99m}Tc$ pertechnetate was milked from the generator with a volume of 8mls. What are the volumes you require for the following kits at the following times? a. 7000MBq @ 8am
