2 of 6 Question A5 Consider the decay chain 211 Bi→ 211 Po 207 Pb. What type of decay does each arrow correspond to? The mean lifetime for each decay is 2.14 min and 0.516 s respectively. If an initial sample is pure 211 Bi, calculate the relative amounts (as a percentage) of 211 Bi, 211 Po and 207 Pb after 2 min.
