3 Jan 1961National Reactor Testing Station, ID30CRIThe SL-1 reactor was a prototype of a reactor intended for easy assembly at remote facilities such as DEW line stations in the Arctic. It used 15 kg of uranium fuel (enriched to 91% U-235), was water moderated, and had a thermal power capacity of 3 MWt. Five aluminum-clad cadmium control rods provided reactor control. The SL-1 had operated 2 years, with an 11-day shutdown for maintenance being completed at the time of the incident. Three workers were reassembling the control rod drives on 3 January in preparation for startup the following day. At about 9:01 PM the three workers were on top of the reactor when one manually removed the center control rod as rapidly as possible, over a 0.5-second period. The reactor became supercritical, with a total energy release of 1.3 x 108 joules (comparable to 30 kg of TNT), producing a steam explosion. The worker who extracted the rod was killed instantly, impaled on the building's ceiling by a control rod. The other two men were burned and thrown by the steam explosion, one dying instantly from impact with a shielding block and the other sustaining head injuries of which he died 2 hours later (maximum dose sustained was possibly 350 rad). The release of radioactive material was largely contained to the building. Emergency responders were alerted by an automated alarm and arrived at the site at 9:10 PM. High radiation readings were measured in the reactor building, delaying entry. At 10:50 PM several responders and contractor personnel removed one man alive, who died shortly afterwards. One body was removed from the reactor building on 4 January and the other on 9 January. Of personnel/responders involved, 22 received doses of 3-27 rads from entering the building and/or handling the casualties.

27 Feb 1996Houston, TX01CRIA radiography company, Larpen of Texas, possessed two cobalt-60 sources (35.3 curies and 8.6 curies) for radiography cameras when it went bankrupt in 1992. The Texas Bureau of Radiation Control ordered the sources impounded in place in October 1992, and requested proper disposal of the sources in 1994. The Bureau had the door to the storage facility welded shut later in 1994, and expressed concern about the source security after the remaining structures were demolished in 1995-1996. On 27 February 1996 three thieves broke into the storage facility and stole the sources to sell them as scrap metal. The buyer took them to a recycling facility where they were declined because they were radioactive. When they were returned to the scrap yard, the delivery man threw the unshielded 35.3 curie source on the ground. The Bureau of Radiation Control recovered the two sources from the scrap yard on 5 March. The delivery man sustained radiation burns on the right thumb and middle finger. Small doses were incurred by scrap yard workers, two children of the scrap yard owner, five investigating police officers, and two Bureau personnel. The three thieves and three people at the scrap yard were arrested.

11 Sep 2001New York City, NY27598700TER-islmFour jetliners on domestic flights from northeastern U.S. airports were hijacked and crashed, three into buildings. Four or five hijackers aboard each aircraft used utility knives to subdue the crew, with a hijacker with flight training taking control of each aircraft. At 8:46 AM American Flight 11 was flown into floors 94 to 99 of the World Trade Center's north tower in New York City. At 9:03 AM United Flight 175 was flown into floors 78 to 84 of the Center's south tower. Both crashes resulted in fires which eventually weakened the towers' structural steel, causing the complete collapse of the south tower at 10:05 AM and the north tower at 10:28 AM. Most people not trapped by the fires had been evacuated from the towers at that point; however, hundreds of police officers and firefighters were in the towers. The World Trade Center collapse caused fires and/or collapses of several nearby buildings, particularly World Trade Center 7 at 5:20 PM. Fatalities due to the Trade Center strikes remain uncertain at 2,759 dead; another 43 missing could not be conclusively linked to the World Trade Center site. These figures include 343 firefighters, 60 police officers, 158 aboard the two aircraft, and 2,235 workers and visitors at the Trade Center. Fatalities aboard the aircraft include 88 passengers and crew on American Flight 11, 60 passengers and crew on United Flight 175, and 5 terrorists on each plane. Total fatalities at the Trade Center site include several hundred citizens of foreign countries: 27 were foreign residents (11 of the UK); 568 were born abroad. Foreigners included individuals from the United Kingdom, India, Columbia, Pakistan, Israel, and Puerto Rico. Another 8,700 were injured, of whom 6,391 received treatment. The attacks were conducted by Al Qaeda with the operation overseen by Osama bin Laden. The United States subsequently assisted opposition forces in Afghanistan in the overthrown of its Taliban ruling party, which has sheltered Al Qaeda.
