摘要：

The half-life of F-18 has been measured using HPGe detectors with a Cs-137 reference source. The counting ratio of 511 keV gamma-rays from F-18 to 622 keV gamma-rays from Cs-137 was fitted for the half-life with a weighted least-square method. Uncertainties due to the systematic effects arising from the measurement of a high activity F-18 source were studied in detail. The half-life of F-18 was found to be (109.72 +/- 0.19) min. The result is in a good agreement with the recommended value of (109.728 +/- 0.019) min evaluated at the Laborotaire National Henri Becquerel (LNHB). (C) 2012 Elsevier Ltd. All rights reserved.
