NONDESTRUCTIVE CHARGED-PARTICLE ACTIVATION-ANALYSIS USING SHORT-LIVED NUCLIDES Academic Article uri icon

abstract

  • The objective of this study was to combine the features of nondestructive determination with speed of analysis. Accordingly, this study was restricted to radioisotopes with half-lives ranging from 1 second to ~1 minute. Furthermore, only those species were considered which emit one or several y-rays besides the 511 keV annihilation peak. Thirty elements were irradiated with protons or 3He particles. Activation with 3He proved to be of little interest in the cases studied. Proton activation was found suitable for the trace determination of the following elements: Se, Br, Y, Zr, La, Pr, Dy, and Nd. Data on their respective specific activities, activation curves, and pertinent y-ray energies (0.3 keV) are given. These elements can be determined in 13 matrix elements which yield little or no activity under the experimental conditions described. Among these are matrices where neutron activation analysis cannot be applied easily because of high neutron absorption or activation cross sections. 1972, American Chemical Society.
