Reactor Accident
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011. The impact of nuclear accidents has been a topic of debate since the first nuclear reactors were constructed in 1954 and has been a key factor in public concern about nuclear facilities. M.V. Ramana.

SL-1
Stationary Low-Power Reactor Number One, also known as SL-1, initially the Argonne Low Power Reactor (ALPR), was a United States Army experimental nuclear reactor in the Western United States, western United States at the Idaho National Laboratory#History, National Reactor Testing Station (NRTS) in Idaho about west of Idaho Falls, Idaho, Idaho Falls, now the Idaho National Laboratory. On January 3, 1961, at 9:01 pm MST, an operator fully pulled out the reactor's central control rod, causing the reactor to go from fully shut down to prompt critical. The intense heat from the nuclear reaction expanded the water inside the reactor core, producing extreme water hammer and causing water, steam, reactor components, debris, and fuel to vent from the top of the reactor where the three operators were working. As the water struck the top of the reactor vessel, it propelled the entire reactor vessel to the ceiling of the reactor room where it struck the overhead crane. A supervisor who ...

Radiotherapy Accident In Costa Rica
The radiotherapy accident in Costa Rica occurred within the Alcyon II radiotherapy unit at San Juan de Dios Hospital in San José, Costa Rica. It was related to a cobalt-60 source that was being used for radiotherapy in 1996. An accidental overexposure of radiotherapy patients treated during August and September 1996 was detected. During the calibration process done after the change of 60Co source on 22 August 1996, a mistake was made in calculating the dose rate, leading to severe overexposure of patients. The error of calibration was detected on 27 September 1996, after which treatments ceased. In the course of the accident, 115 patients received an overdose of radiation and 13 died of radiation-related injuries. The San Juan de Dios Hospital, located in Costa Rica, was one of the major medical facilities offering radiotherapy services in the country. In the mid-1990s, this facility introduced cobalt-60 therapy machines as a means of treating cancer. Radiotherapy is a critical ...
