Determination and control of activity in radioactive waste as part of product control Final report

Research and development investigations have been performed for the control of the activity inventory using the following methods and techniques: non-destructive determination of actinide content in waste through passive neutron measurement including the examination of various parameters on detection efficiency; development of dissolution and decomposition techniques for the various waste groups; and development of methods for individual separation of radioisotopes and measurement of selected nuclides with main emphasis to Fe-55, Ni-59, Ni-63, Sr-90, I-129, Ra-226, Ra-228 and actinides. A comprehensive review of published literature concerning active and passive neutron emission as well as prompt and delayed neutron emission; dissolution and decomposition techniques; rapid chemical separation and measurements techniques for the above mentioned radionuclides; and basic radionuclide data is given.
