Résumé

Glycerophtalic, glycerophosphoric gel, silica gel and diopside have been utilized as decontaminating products carriers. Adherence qualities of these gel decontaminating compounds have been considered. Viscosities have been studied in time and according to temperature and pH. Samples of stainless steel, mild steel, aluminium, copper and "plexiglas" have been contaminated in laboratory, then comparatively treated with depositing gels or dipping into corresponding solutions. This study involves a choice of compounds of gels, which efficiently decontaminate every material for fission products or plutonium. Decontamination with gels is fitted to remote control and is economic owing to its low secondary liquid radwaste production. Its use minimizes the irradiation of workers. Such a process may be proposed within the framework of an optimisation study which is recommended by the 26th Publication of the International Commission of Radiological Protection.
