Abstract
From 4th seminar on activation analysis of the Bundesanstalt fuer Materialpruefung; Berlin, Germany (11 Oct 1973). Charged-particle activation is much more influenced by error sources compared to the neutron activation. This paper discusses as very important error factors: (1) the implantation of atoms coming from residual gas molecules (O, N, C) of the accelerator tube, (2) the heating of the sample during bombardment, (3) the absolute reliability of the particle-activation analysis as to the comparison with standard materials, and (4) the calculation of decay curves of the BETA /sup +/-decaying isotopes activated in the sample.
