摘要

A new method is developed for the determination of energy peak efficiency of 208 keV γ-ray of ~(237)U based on ~(241)Pu/~(237)U secular equilibrium. Plutonium solution was purified to remove Am with Dowex 1 × 2 anion exchange chromatography and the concentration of ~(241)Pu in the purified solution was determined using ~(242)Pu isotope-dilution mass spectrometry on an inductively-coupled plasma mass spectrometry. The solution can be used as calibration source for the determination of energy peak efficiency of 208 keV γ-ray of ~(237)U after 48 days. The method was validated for a planar HPGe detector at the 12 mm above the detector surface. The results showed that this is a simple and economic method for determining the energy peak efficiency of gamma detectors for 208 keV γ-ray of ~(237)U.
