metres of soil contaminated with radium-226 at levels of at least 4 becquerels per gram were condemned as radioactive waste and transported to the low-level waste dump run by Low Level Waste Repositorory near Drigg. Up to twice that volume of less radioactive soils have been tipped onto nearby industrial waste sites. Royal Observer Corps, Carlisle Group During the Second World War the air raid warning organisation No 32 Group Carlisle Royal Observer Corps operated from a city centre building on Norfolk Road, The Laurels, although it was controlled administratively from RAF Kingstown. The association with Kingstown developed further in 1962 when the ROC ceased its aircraft spotting role for the RAF and took on a new role of plotting nuclear explosions and warning the public of approaching radioactive fallout for the UKWMO. A new administration building and a protected, hardened Nuclear Reporting bunker was built at RAF Carlisle. The nuclear bunker was a standard above-ground structure and both the bunker and Headquarters hutting stood on a separate site at Crindledyke just outside the main gates of RAF Carlisle and roughly opposite the station's officers mess. The Carlisle group was redesignated no 22 Group ROC. The ROC also constructed a smaller nuclear reporting post called Kingstown post (OS ref:NY 3837 5920), on the main RAF Carlisle site. The post was also an underground protected bunker but designed for a crew of three observers. The headquarters bunker accommodated an operational crew of around 100 with dormitory and canteen facilities included with the operations room and life support plant. The Royal Observer Corps and its parent organisation the United Kingdom Warning and Monitoring Organisation were stood down in December 1995 after the end of the Cold War and as a result of recommendations in the governments Options for Change review of UK defence. The ROC buildings were demolished in 1996 and replaced by a cellphone communications mast. The foundations of the nuclear bunker can still be partially seen outlined in the concreted yard, which also contains the Air Training Corps hut during recent further development of the site. Continuing RAF links The Royal Air Force still retains close links with the local area, through RAF Spadeadam, the only electronic warfare range still in the UK and one of two in Europe, which holds an annual thanksgiving service in Carlisle Cathedral on Battle of Britain Sunday. Other links with the area are No.
