Answer #1

The given question can be solved by the knowledge to calculate hourly decay when the decay for some greater hour is given

Hence decay rate is -0.01486145599/hour. The negative signs indicate that there is a decay.

214Pb decays to Bi by β- decay which in turn decays to Po also by β- decay. If the half-lives of these decays are 26.8 min and 19.9 minutes respectively, calculate the activity of Bi at t=30 minutes knowing that at t=0 the radioactive sample contained 5.9 mCi of Pb and 1.0 mCi of Bi. How many nuclei of 214Bi have decayed between 1 hour and 2 hours?
