There is an interesting story in the USA media (http://triblive.com/local/valleynewsdispatch/11552998-74/dep-site-contamination) which tells us that a community in Pennsylvania has accepted the capping of land contaminated with Radium rather than a complete decontamination. The UK industry and regulators should research the public consultation process that led to this seemingly sensible decision and see if lessons can be learned for our decommissioning efforts.
This is related to the consultation on decommissioning discussed earlier.
