Читать книгу Industrial and Medical Nuclear Accidents - Jean-Claude Amiard - Страница 21

Nuclear accidents can be of many different types. Criticality accidents that emit large quantities of neutrons and ionizing radiation are often lethal to workers. Industrial accidents due to fire, lightning, earthquakes, tsunamis and so on can damage any protective measures leading to leaks of radioactive materials. However, radiological protection is rarely broken leading to level 4 accidents. The occurrence of a level 5 accident requires an additional supply of energy. This has already occurred in the case of a core meltdown or could occur during an external attack such as a plane crash or a hollow charge shot (ammunition allowing the armor to be pierced).
