文摘

The analysis of naturally occurring radioactive materials using a broad energy germanium detector is reported, along with a description of the rapid measurement of 226Ra and the determination of 227Ac in environmental samples. The detector calibration procedure, sample preparation, and the necessary correction factors have been described. The detector was found useful for the routine analysis of natural radionuclides, with the ability to detect low photon emission peaks at lower gamma energies. The results showed that the direct determination of 226Ra via the 186 keV peak is feasible and the determination of 227Ac using gamma spectrometry is reliable.
