Radioactive decay of unstable atomic nuclei is a fi rst-order process. Th e half-life for the (fi rst-order) radioactive decay of 14C is 5730 a (1 a is the SI unit 1 annum, for 1 year; the nuclide emits b particles, high-energy electrons, with an energy of 0.16 MeV). An archaeological sample contained wood that had only 69 per cent of the 14C found in living trees. What is its age
