摘要：
The half-life of the positron-emitter F-18 has been measured by following the decay rate with three systems ionization chambers. Ge detectors and coincidence with fast scintillators The decay rate was measured for periods of time up to 9 half-lives The combination of the results obtained with the three measuring systems gives a value of T-1/2 = 1.82871 (18)h. in good agreement with recommended data and with an estimated uncertainty lower than any other previously reported value.
