Determination of the half-life and the absolute photon emission intensities for the main gamma-ray energies of 124I
APPLIED RADIATION AND ISOTOPES(2021)
摘要
The National Institute of Standards and Technology (NIST) performed new standardization measurements for 124I. As part of this work the absolute photon emission intensity for the main gamma-rays of 124I were determined using several high-purity germanium (HPGe) detectors. In addition, the half-life for 124I was also determined using an HPGe detector. Ionization chamber measurements were performed for additional sources, but it was not possible to obtain a precise half-life value.
