Measurements of 64Cu and 68Ga half-lives and γ-ray emission intensities

The Cu-64 and Ga-68 half-lives and gamma-ray intensities were measured at IFIN-HH. The determination of absolute photon emission intensities was based on absolute activity standardizations carried out in this laboratory using the 4 pi PC-gamma coincidence method. The half-lives were measured with a well-type ionization chamber. The photon emission intensities (relative and absolute values) were measured with a calibrated high-resolution gamma-ray spectrometer. The results obtained and their uncertainties are discussed and compared with values of other authors. (C) 2012 Elsevier Ltd. All rights reserved.
