found "substantial chromosomal damage" but subsequent reports reported no lasting harm. The technologist was fired, and her license was permanently revoked on March 16, 2011 by the state of California, citing "gross negligence". The hospital's radiology manager, Bruce Fleck, testified that Knickerbocker's conduct was "a rogue act of insanity". August 23–24, 2008 – INES Level 3 – Fleurus, Belgium – Nuclear material leak. A gaseous leak of a radioisotope of iodine, 131I, was detected at a large medical radioisotope laboratory, Institut national des Radio-Eléments. Belgian authorities implemented restrictions on use of local farming produce within 5 km of the leak, when higher-than-expected levels of contamination was detected in local grass. The particular isotope of iodine has a half-life of 8 days. The European Commission sent out a warning over their ECURIE-alert system on the 29th of August. The quantity of radioactivity released into the environment was estimated at 45 GBq 131I, which corresponds to a dose of 160 µSv (effective dose) for a hypothetical person remaining permanently at the site's enclosure. February 2008-August 2009 – A software misconfiguration in a CT scanner used for brain perfusion scanning at Cedars Sinai Medical Center in Los Angeles, California, resulted in 206 patients receiving radiation doses approximately 8 times higher than intended during an 18-month period starting in February 2008. Some patients reported temporary hair loss and erythema. The U.S. Food and Drug Administration (FDA) has estimated that patients received doses between 3 Gy and 4 Gy. 2010s April 2010 – INES level 4 – A 35-year-old man was hospitalized in New Delhi after handling radioactive scrap metal. Investigation led to the discovery of an amount of scrap metal containing 60Co in the Delhi's industrial district of Mayapuri. The 35-year-old man later died from his injuries, while six others remained hospitalized. The radioactivity was from a gammacell 220 research source which was incorrectly disposed of by sale as scrap metal. The gammacell 220 was originally made by Atomic Energy of Canada Limited whose gamma irradiation work is now under the name of Nordion. Nordion does not offer servicing for gammacell 220 machines but can arrange for, in theory, safe disposal of unwanted units. A year later, Delhi Police charged six DU professors from the Chemistry Department for negligent disposal of the radioactive device. July 2010 – During a routine inspection at the Port of Genoa, on Italy's northwest coast, a cargo container from
