Description
Cracking of the glass on cooling and as a result of any handling accident means that the surface area of the glass is greater than the surface of a monolithic block. The glass may break into a few large fragments plus a large number of smaller shards. The estimated surface area of a cracked glass block depends on the size of fragments that are considered. Very small fragments can be neglected because they have small volume and hence small radionuclide content.
