Fukushima 50
Fukushima 50 is a pseudonym given by English-language media to a group of employees at the Fukushima Daiichi Nuclear Power Plant. Following the Tōhoku earthquake and tsunami on 11 March 2011, a related series of nuclear accidents resulted in melting of the cores of three reactors. These 50 employees remained on-site after 750 other workers were evacuated.https://www.telegraph.co.uk/news/worldnews/asia/japan/8408863/Japan-tsunami-Fukushima-Fifty-the-first-interview.html Japan tsunami: Fukushima Fifty, the first interview After TEPCO management proposed withdrawing all its employees from the plant on 14 March, additional manpower was deployed from around Japan.https://www.nytimes.com/2011/03/31/world/asia/31workers.html?src=mv Workers Give Glimpse of Japan’s Nuclear Crisis Some workers traveled on clear roads by convoy from Tokyo.

TEPCO
, also known as or TEPCO, is a Japanese electric utility holding company servicing Japan's Kantō region, Yamanashi Prefecture, and the eastern portion of Shizuoka Prefecture. This area includes Tokyo. Its headquarters are located in Uchisaiwaicho, Chiyoda, Tokyo, and international branch offices exist in Washington, D.C., and London. It is a founding member of strategic consortiums related to energy innovation and research; such as JINED, INCJ and MAI. In 2007, TEPCO was forced to shut the Kashiwazaki-Kariwa Nuclear Power Plant after the Niigata-Chuetsu-Oki earthquake. That year it posted its first loss in 28 years. Corporate losses continued until the plant reopened in 2009. Following the 2011 Tōhoku earthquake and tsunami, one of its power plants was the site of one of the world's most serious ongoing nuclear disaster, the Fukushima Daiichi nuclear disaster. TEPCO could face ¥ ($) in special losses in the current business year to March 2012, and the Japanese government ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sievert
The sievert (symbol: SvNot be confused with the sverdrup or the svedberg, two non-SI units that sometimes use the same symbol.) is a unit in the International System of Units (SI) intended to represent the stochastic health risk of ionizing radiation, which is defined as the probability of causing radiation-induced cancer and genetic damage. The sievert is important in dosimetry and radiation protection. It is named after Rolf Maximilian Sievert, a Swedish medical physicist renowned for work on radiation dose measurement and research into the biological effects of radiation. The sievert is used for radiation dose quantities such as equivalent dose and effective dose (radiation), effective dose, which represent the risk of external radiation from sources outside the body, and committed dose, which represents the risk of internal irradiation due to inhaled or ingested radioactive substances. According to the International Commission on Radiological Protection (ICRP) one sievert r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naoto Kan
is a Japanese politician who was Prime Minister of Japan and President of the Democratic Party of Japan (DPJ) from June 2010 to September 2011. Kan was the first Prime Minister since the resignation of Junichiro Koizumi in 2006 to serve for more than one year, with his predecessors Yukio Hatoyama, Tarō Asō, Yasuo Fukuda, and Shinzō Abe either resigning prematurely or losing an election. On 26 August 2011, Kan announced his resignation. Yoshihiko Noda was elected as his successor. On 1 August 2012, United Nations Secretary-General Ban Ki-moon announced Kan would be one of the members of the UN high-level panel on the post-2015 development agenda. Early life and education Kan was born in Ube, Yamaguchi, the eldest son of Hisao Kan, the executive director of the glass manufacturing company Central Glass. He graduated in 1970 from the Tokyo Institute of Technology and became a licensed ''benrishi'' (patent agent/attorney) in 1971. Diet career After graduating from college, K ...

Exclusion Zone
An exclusion zone is a territorial division established for various, case-specific purposes. Per the United States Department of Defense, an exclusion zone is a territory where an authority prohibits specific activities in a specific geographic area (see military exclusion zone). These temporary or permanent zones are created for control of populations for safety, crowd control, or military purposes, or as a border zone. Nuclear disaster exclusion zones Large-scale geographic exclusion zones have been established after major disasters in which radioactive particles were released into the environment: *Kyshtym disaster (1957) **East Ural Nature Reserve – Russia, established 1968. *Chernobyl disaster (1986) **Chernobyl Exclusion Zone – Ukraine, established 1986. **Polesie State Radioecological Reserve – Belarus, established 1988. *Fukushima nuclear disaster (2011) ** Fukushima Exclusion Zone – Japan, established 2011. Ordnance exclusion zones *Zone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiation Burn
A radiation burn is a damage to the skin or other biological tissue and organs as an effect of radiation. The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns. As the ionizing radiation interacts with cells within the body—damaging them—the body responds to this damage, typically resulting in erythema—that is, redness around the damaged area. Radiation burns are often discussed in the same context as radiation-induced cancer due to the ability of ionizing radiation to interact with and damage DNA, occasionally inducing a cell to become cancerous. Cavity magnetrons can be improperly used to create surface and internal burning. Depending on the photon energy, gamma radiation can cause deep gamma burns, with 60Co in ...

Containment Building
A containment building is a reinforced steel, concrete or lead structure enclosing a nuclear reactor. It is designed, in any emergency, to contain the escape of radioactive steam or gas to a maximum pressure in the range of . The containment is the fourth and final barrier to radioactive release (part of a nuclear reactor's defence in depth strategy), the first being the fuel ceramic itself, the second being the metal fuel cladding tubes, the third being the reactor vessel and coolant system. Each nuclear plant in the US is designed to withstand certain conditions which are spelled out as "Design Basis Accidents" in the Final Safety Analysis Report (FSAR). The FSAR is available for public viewing, usually at a public library near the nuclear plant. The containment building itself is typically an airtight steel structure enclosing the reactor normally sealed off from the outside atmosphere. The steel is either free-standing or attached to the concrete missile shield. In the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ionizing Radiation
Ionizing radiation (or ionising radiation), including nuclear radiation, consists of subatomic particles or electromagnetic waves that have sufficient energy to ionize atoms or molecules by detaching electrons from them. Some particles can travel up to 99% of the speed of light, and the electromagnetic waves are on the high-energy portion of the electromagnetic spectrum. Gamma rays, X-rays, and the higher energy ultraviolet part of the electromagnetic spectrum are ionizing radiation, whereas the lower energy ultraviolet, visible light, nearly all types of laser light, infrared, microwaves, and radio waves are non-ionizing radiation. The boundary between ionizing and non-ionizing radiation in the ultraviolet area is not sharply defined, as different molecules and atoms ionize at different energies. The energy of ionizing radiation starts between 10 electronvolts (eV) and 33 eV. Typical ionizing subatomic particles include alpha particles, beta particles, and neutrons. ...

Mainichi Shimbun
The is one of the major newspapers in Japan, published by In addition to the ''Mainichi Shimbun'', which is printed twice a day in several local editions, Mainichi also operates an English language news website called ''The Mainichi'' (previously ''Mainichi Daily News''), and publishes a bilingual news magazine, ''Mainichi Weekly''. It also publishes paperbacks, books and other magazines, including a weekly news magazine, ''Sunday Mainichi''. It is one of the four national newspapers in Japan; the other three are the ''Asahi Shimbun'', the ''Yomiuri Shimbun'' and the '' Nihon Keizai Shimbun''. The Sankei Shimbun and The ''Chunichi Shimbun'' are not currently in the position of a national newspaper despite a large circulation for the both respectively. History The history of the ''Mainichi Shinbun'' began with the founding of two papers during the Meiji period. The ''Tokyo Nichi Nichi Shimbun'' was founded first, in 1872. The ''Mainichi'' claims that it is the oldest existing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asahi Shimbun
is one of the four largest newspapers in Japan. Founded in 1879, it is also one of the oldest newspapers in Japan and Asia, and is considered a newspaper of record for Japan. Its circulation, which was 4.57 million for its morning edition and 1.33 million for its evening edition as of July 2021, was second behind that of the ''Yomiuri Shimbun''. By print circulation, it is the third largest newspaper in the world behind the ''Yomiuri'', though its digital size trails that of many global newspapers including ''The New York Times''. Its publisher, is a media conglomerate with its registered headquarters in Osaka. It is a privately held family business with ownership and control remaining with the founding Murayama and Ueno families. According to the Reuters Institute Digital Report 2018, public trust in the ''Asahi Shimbun'' is the lowest among Japan's major dailies, though confidence is declining in all the major newspapers.
