Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
Minamata disease (Japanese: 水俣病, Hepburn: Minamata-byō) is a neurological disease caused by severe mercury poisoning. Signs and symptoms include ataxia , numbness in the hands and feet, general muscle weakness , loss of peripheral vision , and damage to hearing and speech .
This represents a much lower level then the amount required to increase a person's risk of cancer. 100 mSv represents the level at which a definitive increased risk of cancer occurs. Radiation above this level increases the risk of cancer, and after 400 mSv radiation poisoning can occur, but is unlikely to be fatal. [188] [189] [190]
The crew suffered acute radiation syndrome (ARS) for a number of weeks after the Bravo test in March. All recovered from the immediate effects of the American test detonation except for Kuboyama Aikichi, the boat's chief radioman, who died on September 23, 1954, from complications of radiation sickness.

The area has effectively become an unplanned marine-life sanctuary; this has also occurred in Europe in the Chernobyl exclusion zone, [61] where scientists are studying the effects of radiation on animal life. Most fish have relatively short lifespans, and Palumbi suggested that "it is possible the worst-affected fish died off many decades ago ...
Radioresistance is the level of ionizing radiation that organisms are able to withstand.. Ionizing-radiation-resistant organisms (IRRO) were defined as organisms for which the dose of acute ionizing radiation (IR) required to achieve 90% reduction (D10) is greater than 1,000 gray (Gy) [1]
VHS disease in a gizzard shad. Viral hemorrhagic septicemia (VHS) is a deadly infectious fish disease caused by Viral hemorrhagic septicemia virus. It afflicts over 50 species of freshwater and marine fish in several parts of the Northern Hemisphere. [1] Different strains of the virus occur in different regions, and affect different species.
Doctors called it the "special disease" because they were not allowed to note radiation in their diagnoses as long as the facility was secret. In the village of Metlino , it was found that 65% of residents were suffering from chronic radiation sickness. [citation needed] Workers at the plutonium plant were also affected.
