Abstract  

Low-energy photon spectrometry with -spectrometry was used to determine the environmental concentrations of low-level actinides and other nuclides, especially210Pb and210Po. The isotopic ratio of240Pu/239Pu was successfully determined by measuring Lx-ray/-ray counting ratio. A reliable method has been developed for the determination of extremely low-level237Np global fallout in environmental samples. The non-destructive determination by Ge-LEPS for natural210Pb in various samples (tobacco leaves, commercially available tobacco, etc.) was also carried out with the determination of210Po by -spectrometry using209Po as a yield tracer.
