Advanced Technologies for Radioactive Waste Characterization and Free Release Measurement

Abstract

Nuclear power generation, medicine and industry are widely using radioactive materials and as a result generating large amounts of radwaste that has either to be stored or free-released to the environment. Free-release procedures require precise detection of radionuclides that can remain in waste. The activity of such nuclides can be on a level of natural background or even below. That requires the background influence to be removed. ENVINET has developed low radioactive materials which can be used to form a low background measuring chamber. The ceramic based material has better characteristics than lead, which is usually used for such purposes.
