Note in Table 12.2 that the half-lives of two abundant isotopes of tellurium are more than 1021 years. (a) What is the decay rate per unit mass of 128Te, which decays by emitting two β-, in units of s-1 . kg-1? (b) How much mass of a natural sample of tellurium would it take to measure a decay rate of 10 β-/s for 128Te?
