Cross-section of a cement-bound waste package
This cross-section of a cemented waste package illustrates one of the principles for conditioning, namely using a matrix to immobilise radioactive materials. A radioactive object is embedded in cement and then placed inside a container. Despite its simplicity, a cement matrix solution is adequate for low-level, short-lived radioactive waste. For intermediate- and high-level, long-lived waste, much more durable matrices must be used.
