Chernobyl Exclusion Zone
The Chernobyl Nuclear Power Plant Zone of Alienation, also called the 30-Kilometre Zone or simply The Zone, was established shortly after the 1986 Chernobyl disaster in the Ukrainian SSR of the Soviet Union. Initially, Soviet authorities declared an exclusion zone spanning a radius around the Chernobyl Nuclear Power Plant, designating the area for evacuations and placing it under military control. Its borders have since been altered to cover a larger area of Ukraine: it includes the northernmost part of Vyshhorod Raion in Kyiv Oblast, and also adjoins the Polesie State Radioecological Reserve in neighbouring Belarus. The Chernobyl exclusion zone is managed by an agency of the State Emergency Service of Ukraine, while the power plant and its sarcophagus and the New Safe Confinement are administered separately. The current area of approximately in Ukraine is where radioactive contamination is the highest, and public access and habitation are accordingly restricted. Other ...

Exclusion Zone
An exclusion zone is a geographic area in which specific activities are prohibited by an authority. The United States Department of Defense defines 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.

Disaster Tourism
Disaster tourism is the practice of visiting locations at which an environmental disaster, either natural or human-made, has occurred. Although a variety of disasters are the subject of subsequent disaster tourism, the most common disaster tourist sites are areas surrounding volcanic eruptions. Opinions on the morality and impact of disaster tourism are divided. Advocates of disaster tourism often claim that the practice raises awareness of the event, stimulates the local economy, and educates the public about the local culture, while critics claim that the practice is exploitative, profits on loss, and often mischaracterize the events in question. Motivations An article by ''Smartertravel'' defines the motivations present in individuals practicing disaster tourism. Attraction is typically derived from personal connection in a social, academic or cultural essence. Another population of visitors hope to aid in providing relief to the affected areas—some directly through volunte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiation Exposure
Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. As of 2007, "medical radiation exposure" was defined by the International Commission on Radiological Protection as exposure incurred by people as part of their own medical or dental diagnosis or treatment; by persons, other than those occupationally exposed, knowingly, while voluntarily helping in the support and comfort of patients; and by volunteers in a programme of biomedical research involving their exposure. Common medical tests and treatments involving radiation include X-rays, CT scans, mammography, lung ventilation and perfusion scans, bone scans, cardiac perfusion scan, angiography, radiation therapy, and more. Each type of test carries its own amount of radiation exposure. There are two general categories of adverse health effects caused by radiation e ...

Radioactive Contamination
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of Radioactive decay, radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition). Such contamination presents a hazard because the radioactive decay of the contaminants produces ionizing radiation (namely alpha particle, alpha, beta particle, beta, gamma rays and free neutrons). The degree of hazard is determined by the concentration of the contaminants, the energy of the radiation being emitted, the type of radiation, and the proximity of the contamination to organs of the body. It is important to be clear that the contamination gives rise to the radiation hazard, and the terms "radiation" and "contamination" are not interchangeable. The sources of radioactive pollution can be classified into two groups: natural and man-made. Follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chernobyl New Safe Confinement
The New Safe Confinement (NSC or New Shelter; ) is a structure put in place in 2016 to confine the remains of the number 4 reactor unit at the Chernobyl Nuclear Power Plant, in Ukraine, which was destroyed during the Chernobyl disaster in 1986. The structure also encloses the temporary Shelter Structure (sarcophagus) that was built around the reactor immediately after the disaster. The New Safe Confinement is designed to prevent the release of radioactive contaminants, protect the reactor from external influence, facilitate the disassembly and decommissioning of the reactor, and prevent water intrusion. The New Safe Confinement is a megaproject that is part of the Shelter Implementation Plan and supported by the Chernobyl Shelter Fund. It was designed with the primary goal of confining the radioactive remains of reactor 4 for 100 years. It also aims to allow for a partial demolition of the original sarcophagus, which was hastily constructed by Chernobyl liquidators after a ...

Chernobyl Nuclear Power Plant Sarcophagus
The Chernobyl Nuclear Power Plant sarcophagus or Shelter Structure (, ) is a massive steel and concrete structure covering the nuclear reactor number 4 building of the Chernobyl Nuclear Power Plant. Built in the aftermath of the 1986 Chernobyl disaster, the sarcophagus was designed to limit radioactive contamination of the environment by encasing the most dangerous area and protecting it from climate exposure. The sarcophagus locked in an estimated of radioactive lava-like corium, of highly contaminated dust and of uranium and plutonium. Structurally, the sarcophagus is largely supported by the damaged reactor building. By 1996, the structure had deteriorated to the point where numerous stabilization measures were required. Internal radiation levels were estimated to be as high as per hour in certain areas (normal background radiation in cities is usually around per hour, and a lethal dose is over 5 hours).. By 2017, the sarcophagus was surrounded by the New Safe Confi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
