The Vitrification plant at Sellafield nuclear power station. Highly radioactive waste is ground down and then poured into these stainless steel flasks along with liquid glass. Once the mixture sets, the flasks are stored, (at the moment they are stored at Sellafield, but in the long term they will go to the long term waste repository, hundreds of metres below ground. This repository has not yet been built). These flasks are emitting between 1000-2000 Sieverts per hour, 5 Sieverts per hour is enough to kill a human being. This photograph was taken through 1.5 metre thick lead impregnated glass..
