Chernobyl Disaster Effects
The Chernobyl disaster of 26 April 1986 triggered the release of radioactive contamination into the atmosphere in the form of both particulate and gaseous Radionuclide, radioisotopes. , it remains the world's largest known release of Radioactive decay, radioactivity into the natural environment. The work of the Scientific Committee on Problems of the Environment (SCOPE) suggests that the Chernobyl disaster cannot be directly compared to Nuclear weapons testing, atmospheric tests of nuclear weapons by simply saying that it is better or worse. This is partly because the isotopes released at the Chernobyl Nuclear Power Plant tended to be longer-lived than those released by the detonation of Nuclear weapon, atomic bombs. It is estimated that the Chernobyl disaster caused US$235 billion in economic damages. Radiation effects on humans In a 2009 United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) study, the Chernobyl disaster, Chernobyl accident had by ...

Estimated Number Of Deaths From The Chernobyl Nuclear Disaster, OWID
Estimation (or estimating) is the process of finding an estimate or approximation, which is a value that is usable for some purpose even if input data may be Complete measure, incomplete, uncertainty, uncertain, or Instability, unstable. The value is nonetheless usable because it is derived from the best information available.C. Lon Enloe, Elizabeth Garnett, Jonathan Miles, ''Physical Science: What the Technology Professional Needs to Know'' (2000), p. 47. Typically, estimation involves "using the value of a statistic derived from a sample (statistics), sample to estimate the value of a corresponding population parameter".Raymond A. Kent, "Estimation", ''Data Construction and Data Analysis for Survey Research'' (2001), p. 157. The sample provides information that can be projected, through various formal or informal processes, to determine a range most likely to describe the missing information. An estimate that turns out to be incorrect will be an overestimate if the estimate exc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collective Dose
The collective effective dose, dose quantity S, is calculated as the sum of all individual effective doses over the time period or during the operation being considered due to ionizing radiation. It can be used to estimate the total health effects of a process or accidental release involving ionizing radiation to an exposed population. The total collective dose is the dose to the exposed human population between the time of release until its elimination from the environment, perhaps integrating to time equals infinity. However, doses are generally reported for specific populations and a stated time interval. The International Commission on Radiological Protection (ICRP) states: "To avoid aggregation of low individual doses over extended time periods and wide geographical regions the range in effective dose and the time period should be limited and specified. Limitations The ICRP states; "Collective effective dose is an instrument for optimisation, for comparing radiological technolo ...

Forsmark Nuclear Power Plant
Forsmark Nuclear Power Plant is a nuclear power plant in Forsmark, Sweden that provides 14% of Sweden's total electricity output, and also the site of the Swedish Final repository for radioactive operational waste. It is operated by a company mainly owned by Vattenfall. The radiation monitors at Forsmark were the first outside the Soviet Union to detect the elevated radiation levels resulting from the Chernobyl disaster in April 1986, over 1,000 km away, forcing the Soviet government to publicly acknowledge it after two days of them trying to cover it up. Reactors Forsmark NPP has three Boiling water reactors: * F1 with an ABB Atom BWR 69 at 2928 MW thermal and 1010 MWe net was first connected to the grid on 5 June 1980, and commenced commercial operation on 10 December 1980. It has two turbo-alternators. * F2 with an ABB Atom BWR 69 at 3253 MW thermal and 1120 MWe net was first grid connected on 15 December 1980 and commenced commercial operation on 7 July 1981. It ...

Papillary Thyroid Cancer
Papillary thyroid cancer (papillary thyroid carcinoma, PTC) is the most common type of thyroid cancer, representing 75 percent to 85 percent of all thyroid cancer cases.Chapter 20 in: 8th edition. It occurs more frequently in women and presents in the 20–55 year age group. It is also the predominant cancer type in children with thyroid cancer, and in patients with thyroid cancer who have had previous radiation to the head and neck. It is often well- differentiated, slow-growing, and localized, although it can metastasize. Diagnosis Papillary thyroid carcinoma is usually discovered on routine examination as an asymptomatic thyroid nodule that appears as a neck mass. In some instances, the mass may have produced local symptoms. This mass is normally referred to a fine needle aspiration biopsy (FNA) for investigation. FNA accuracy is very high and it is a process widely used in these cases. Other investigation methods include ultrasound imaging and nuclear scan. The ultrasound is ...

Rubidium
Rubidium is a chemical element; it has Symbol (chemistry), symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. Rubidium is the first alkali metal in the group to have a density higher than Properties of water, water. On Earth, natural rubidium comprises two isotopes: 72% is a stable isotope Rb, and 28% is slightly radioactive Rb, with a half-life of 48.8 billion years – more than three times as long as the estimated age of the universe. German chemists Robert Bunsen and Gustav Kirchhoff discovered rubidium in 1861 by the newly developed technique, Atomic emission spectroscopy#Flame emission spectroscopy, flame spectroscopy. The name comes from the Latin word , meaning deep red, the color of its emission spectrum. Rubidium's compounds have various chemical and electronic applications. Rubidium metal is easily vaporized and has a convenient spectral absorption range, making it a frequent target for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tellurium
Tellurium is a chemical element; it has symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in its native form as elemental crystals. Tellurium is far more common in the Universe as a whole than on Earth. Its extreme rarity in the Earth's crust, comparable to that of platinum, is due partly to its formation of a volatile hydride that caused tellurium to be lost to space as a gas during the hot nebular formation of Earth. Tellurium-bearing compounds were first discovered in 1782 in a gold mine in Kleinschlatten, Transylvania (now Zlatna, Romania) by Austrian mineralogist Franz-Joseph Müller von Reichenstein, although it was Martin Heinrich Klaproth who named the new element in 1798 after the Latin 'earth'. Gold telluride minerals are the most notable natural gold compounds. However, they are not a commercially signif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
