More than 30 people were over-exposed to radiation when the starboard reactor cooling system failed and the reactor temp rose uncontrollably. Emergency repairs ordered by the captain successfully cooled the reactor and avoided meltdown, but exposed the workers to high levels of radiation. [17] 8 Radiation accident in Morocco: 1984 March
Nikolai Vladimirovich Zateyev (Russian: Николай Владимирович Затеев; c. June 30, 1926 – 28 August 1998) was a Russian submariner and a Captain First Rank in the Soviet Navy, notable as the commander of the ill-fated Soviet submarine K-19 in July 1961 during the Hotel class submarine's nuclear-reactor coolant leak.
A radiation alarm was transmitted only after a chemical officer and a doctor requested it. K-27 resurfaced and returned from training area to its home base using the starboard reactor. The submarine was placed at pier in Severomorsk and a depot ship continuously piped steam to the submarine to avoid cooling of heat-transfer metal in the reactor ...
Criticality accidents are divided into one of two categories: Process accidents, where controls in place to prevent any criticality are breached;; Reactor accidents, which occur due to operator errors or other unintended events (e.g., during maintenance or fuel loading) in locations intended to achieve or approach criticality, such as nuclear power plants, nuclear reactors, and nuclear ...
The Soviet Union conducted 456 nuclear tests at Semipalatinsk from 1949 until 1989 with little regard for their effect on the local people or environment. The full impact of radiation exposure was hidden for many years by Soviet authorities and has only come to light since the test site closed in 1991. [59] 2007 ISO radioactivity danger symbol ...

With the help of mannequins named Helga and Zohar and sensors placed inside a spacecraft, scientists have collected valuable data about radiation exposure for astronauts outside Earth's sheltering ...
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
