grafts. After 893 days in the hospital, he was declared dead after sepsis caused by complications and infections of a radiation ulcer on the subject's back. The disposal team consisted of 24 men who were restricted to a maximum of 40 seconds worth of exposure (max. 20mSv) each while transferring the canisters to lead-lined drums. March 11, 2002 – INES Level 2 – A 2.5 tonne 60Co gamma source was transported from Cookridge Hospital, Leeds, to Sellafield with defective shielding at the bottom of the container. As the radiation escaped from the package downwards into the ground, it is thought that this event did not cause any injury or disease in either a human or an animal. This event was treated in a serious manner because the defense in depth type of protection for the source had been eroded. Had the container been tipped over in a road crash, people at the scene would have been exposed to 83.5 Gy/h. The company responsible for the transport of the source, AEA Technology plc, was fined £250,000 by a British court. 2003 – Cape of Navarin, Chukotka Autonomous Okrug, Russia. A radioisotope thermoelectric generator (RTG) located on the Arctic shore was discovered in a highly degraded state. The exposure rate at the generator surface was as high as 15 R/h; in July 2004 a second inspection of the same RTG showed that gamma radiation emission had risen to 87 R/h and that 90Sr had begun to leak into the environment. In November 2003, a completely dismantled RTG located on the island of Yuzhny Goryachinsky in the Kola Bay was found. The generator's radioactive heat source was found on the ground near the shoreline in the northern part of the island. September 10, 2004 – Yakutia, Russia. Two radioisotope thermoelectric generators were dropped 50 meters onto the tundra at Zemlya Bunge island during an airlift when the helicopter flew into heavy weather. According to the nuclear regulators, the impact compromised the RTGs' external radiation shielding. At a height of 10 meters above the impact site, the intensity of gamma radiation was measured at 4 mSv/h. 2005 – Dounreay, U.K. In September, the site's cementation plant was closed when 266 liters of radioactive reprocessing residues were spilled inside containment. In October, another of the site's reprocessing laboratories was closed down after nose-blow tests of eight workers tested positive for trace radioactivity. 2005-2006 – :
