The effects of radiation on cement matrix wasteforms

Creators

Description

The effects of γ-irradiation have been investigated on a range of cement encapsulated intermediate level wastes. The majority of the wasteforms do not degrade mechanically as a result of irradiation. The exception was a wasteform containing borates, which disintegrated at doses in excess of 6 MGy. Gas evolution/absorption during irradiation has been characterised. In most cases hydrogen is evolved (G(H2) approx. 0.05) and oxygen absorbed. Nitrate-bearing wastes show reduced hydrogen evolution and a tendency to oxygen evolution. The effects of radiation on the leaching of a number of radionuclides from the wasteforms have been investigated. Some effects were observed. Discussion of the results is provided within the limits of existing information. (author)
