Resumen | A nondestructive method based on low-energy, highresolution photon spectrometry is presented which allows
accurate determination of 239Pu, 240Pu, and 241Am (as a daughter
of 241Pu) activities in radioactive particles ... A nondestructive method based on low-energy, highresolution photon spectrometry is presented which allows accurate determination of 239Pu, 240Pu, and 241Am (as a daughter of 241Pu) activities in radioactive particles containing relatively high levels of plutonium isotopes. The proposed method requires only one measurement for the establishment of an absolute efficiency curve. Since the density and composition of the radioactive particles of interest may vary, a self-absorption correction is required for the accurate determination of isotopic activities and ratios. This correction is carried out for each individual particle using the convenient gamma-ray emissions of 241 Am. |
