Radiation Accident In Morocco
In March 1984, a serious radiation accident occurred in Morocco, at the Mohammedia nuclear power plant, where eight people died from pulmonary hemorrhaging caused by overexposure to radiation from a lost iridium-192 source. Other individuals also received significant overdoses of radiation that required medical attention. Three people were sent to the Curie Institute in Paris for treatment of radiation poisoning. The source was used to radiograph welds and became separated from its shielded container. As the source, an iridium pellet, itself had no markings indicating it was radioactive, a worker took it home, where it stayed for some weeks, exposing the family to radiation. The laborer, his family, and some relatives were the eight deaths caused by the accident.

Pulmonary Hemorrhage
Pulmonary hemorrhage (or pulmonary haemorrhage) is an acute bleeding from the lung, from the upper respiratory tract and the trachea, and the pulmonary alveoli. When evident clinically, the condition is usually massive.Pulmonary Hemorrhage Intensive Care Nursery House Staff Manual. UCSF Children's Hospital at UCSF Medical Center. 2004:The Regents of the . Retrieved 2008-10-28. The onset of pulmonary hemorrhage is characterized by a cough productive of ( |
Radiotherapy Accident In Costa Rica
The radiotherapy accident in Costa Rica occurred with 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 December 1997. In the course of the accident, 114 patients received an overdose of radiation and 13 died of radiation-related injuries. In 2001, the radiophysicist whose mistake caused the radiation overdoses was charged with 16 culpable homicides and sentenced to six years in prison.

Radiation Accidents And Incidents
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: * ''electromagnetic radiation'', such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ) * ''particle radiation'', such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation (particles of non-zero rest energy) * '' acoustic radiation'', such as ultrasound, sound, and seismic waves (dependent on a physical transmission medium) * ''gravitational radiation'', that takes the form of gravitational waves, or ripples in the curvature of spacetime Radiation is often categorized as either ''ionizing'' or ''non-ionizing'' depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference i ...

Man-made Disasters In Morocco
Artificiality (the state of being artificial or manmade) is the state of being the product of intentional human manufacture, rather than occurring naturally through processes not involving or requiring human activity. Connotations Artificiality often carries with it the implication of being false, counterfeit, or deceptive. The philosopher Aristotle wrote in his ''Rhetoric'': However, artificiality does not necessarily have a negative connotation, as it may also reflect the ability of humans to replicate forms or functions arising in nature, as with an artificial heart or artificial intelligence. Political scientist and artificial intelligence expert Herbert A. Simon observes that "some artificial things are imitations of things in nature, and the imitation may use either the same basic materials as those in the natural object or quite different materials. Herbert A. Simon, ''The Sciences of the Artificial'' (1996), p. 4. Simon distinguishes between the artificial and the synt ...

United States Nuclear Regulatory Commission
The Nuclear Regulatory Commission (NRC) is an independent agency of the United States government tasked with protecting public health and safety related to nuclear energy. Established by the Energy Reorganization Act of 1974, the NRC began operations on January 19, 1975, as one of two successor agencies to the United States Atomic Energy Commission. Its functions include overseeing reactor safety and security, administering reactor licensing and renewal, licensing radioactive materials, radionuclide safety, and managing the storage, security, recycling, and disposal of spent fuel. History Prior to 1975 the Atomic Energy Commission was in charge of matters regarding radionuclides. The AEC was dissolved, because it was perceived as unduly favoring the industry it was charged with regulating.John Byrne and Steven M. Hoffman (1996). ''Governing the Atom: The Politics of Risk'', Transaction Publishers, p. 163. The NRC was formed as an independent commission to oversee nuclear ene ...

Radiotherapy Accident In Zaragoza
The 1990 Clinic of Zaragoza radiotherapy accident was a radiological accident that occurred from 10 to 20 December 1990, at the Clinic of Zaragoza, in Aragon, Spain. In the accident, at least 27 patients were injured, and 11 of them died due to the overexposure, according to International Atomic Energy Agency (IAEA). All of the injured were cancer patients receiving external beam radiotherapy. Chronology On 7 December 1990, a technician performed maintenance on an electron accelerator at the Clinic of Zaragoza. On 10 December, it returned to service after the repairs. Affected patients immediately suffered burns on the skin of the irradiated area, as well as inflammation of the internal organs and bone marrow. The first overexposed patient died on 16 February 1991, two months after irradiation. Fatalities increased until, on 25 December 1991, the last of a total of 25 patients died. The IAEA established that 11 of the deaths were due to the faulty maintenance. On 19 December, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goiânia Accident
The Goiânia accident was a radioactive contamination accident that occurred on September 13, 1987, in Goiânia, Goiás, Brazil, after a forgotten radiotherapy source was stolen from an abandoned hospital site in the city. It was subsequently handled by many people, resulting in four deaths. About 112,000 people were examined for radioactive contamination and 249 of them were found to have been contaminated. In the consequent cleanup operation, topsoil had to be removed from several sites, and several houses were demolished. All the objects from within those houses, including personal possessions, were seized and incinerated. ''Time'' magazine has identified the accident as one of the world's "worst nuclear disasters" and the International Atomic Energy Agency (IAEA) called it "one of the world's worst radiological incidents". Description of the source The radiation source in the Goiânia accident was a small capsule containing about of highly radioactive caesium chlori ...

Nuclear And Radiation Accidents
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, 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. Nuclear Power: Economic, Safety, Health, and Environmental Issues of Near-Term Technologies, ''Annual Review of Environment and Resources'', 2009, 34, p. 136.

Radiation Protection
Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this". Exposure can be from a source of radiation external to the human body or due to internal irradiation caused by the ingestion of radioactive contamination. Ionizing radiation is widely used in industry and medicine, and can present a significant health hazard by causing microscopic damage to living tissue. There are two main categories of ionizing radiation health effects. At high exposures, it can cause "tissue" effects, also called "deterministic" effects due to the certainty of them happening, conventionally indicated by the unit gray and resulting in acute radiation syndrome. For low level exposures there can be statistically elevated risks of radiation-induced cancer, called " stochastic effects" due to the uncertainty of them happening, ...
