On 19 June 2012 Minister of Science Hirofumi Hirano said that Japan would review the decision of the Science Ministry and the Nuclear-Safety Agency in 2011 to ignore the radiation maps provided by the United States. He defended his ministry's handling of the matter with the remark that its task was to measure radiation levels on land.
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 ...
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.
A 1988 UK government estimate stated that there would be around 100 deaths by 2007 as a result of exposure to radioactive material. [3] [4] More recent academic research carried out in 2007 estimated that 100 to 240 deaths were caused by the radiation leak. [5] [6] [7] 1 due to radiation, 51 due to evacuation. Fukushima nuclear disaster: 2011 March
Globally, there have been at least 99 (civilian and military) recorded nuclear reactor accidents from 1952 to 2009 (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage, the amount the US federal government uses to define major energy accidents that must be reported), totaling US$20.5 billion in property damages.
This report concluded that 134 staff and emergency workers developed acute radiation syndrome and of those 28 died of radiation exposure within three months. Many of the survivors developed skin conditions and radiation induced cataracts, and 19 had since died, but from conditions not necessarily associated with radiation exposure.
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.
The effects of the 1979 Three Mile Island nuclear accident are widely agreed to be very low by scientists in the relevant fields. The American Nuclear Society concluded that average local radiation exposure was equivalent to a chest X-ray and maximum local exposure equivalent to less than a year's background radiation. [1]
