Large-volume instrumental photon activation analysis (IPAA) was used for the investigation of shredded electronic waste material.
Sample masses from 1 to 150 grams were analyzed to obtain an estimate of the minimum sample size to be taken to achieve a
representativeness of the results which is satisfactory for a defined investigation task. Furthermore, the influence of irradiation
and measurement parameters upon the quality of the analytical results were studied. Finally, the analytical data obtained
from IPAA and instrumental neutron activation analysis (INAA), both carried out in a large-volume mode, were compared. Only
parts of the values were found in satisfactory agreement.
