Rapport Technique NTB 84-10

The general subject of monitoring radioactive wastes has been presented in the Nagra Technical Report NTB 82-02. This present report is an updating of NTB 82-02. The information in this supplement has been extracted from completely new sources. It will also serve as the basis for a proposed study, the objective of which will be to demonstrate the characterisation and control of radioactive wastes using monitoring techniques. Up to the present time waste monitoring techniques have concentrated on Uranium and Plutonium because of their importance and of the difficulty of their measurement. This continues to be the case in this report. The monitoring of radionuclides emitting high energy gammas will be expanded, particularly in regard to quantitative measurements. Finally, all radionuclides which can represent a hazard during final storage, whether alpha, beta or gamma emitting, will be studied (mentioned study) with respect to the possibility for direct and/or indirect analysis and measurement of radwaste.
