4πβ-γ（HPGe） Method for Activity Measurement

    Graphical Abstract
    • Abstract
  • The 4πβ-γ（HPGe） method for activity measurement was described. The HPGe detector is taken to replace the NaI（Tl） detector in the usual 4πβ-γ system, which can detect γ-ray more accurately. With proper selection of γ-ray, the approach can simply determine activity. With the measurements of 133Ba and 131I, it is concluded that the 4πβ-γ（HPGe） anticoincidence method is an accurate and credible method for activity measurement.
