摘要：

Bromine can be determined by neutron activation analysis (NNA) through either the activation of Br-79(50.69% naturally abundant) or Br-81(49.31% naturally abundant). When Br-79 is activated, both Br-80m and Br-80 are produced. Br-80m(4.42h) decays to Br-80(17.66m) which then beta decays to either Se-80 or Kr-80. If one would like to determine bromine concentrations with short lived NAA, special equations must be used to account for the parent daughter relationship between Br-80m and Br-80 after their simultaneous production. The development of the equations needed to calculate bromine concentrations with short-lived NAA is described including variations on irradiation times, decay times, and count times.
