Crimes Involving Radioactive Substances
This is a list of criminal (or arguably, allegedly, or potentially criminal) acts intentionally involving radioactive substances. Inclusion in this list does not necessarily imply that anyone involved was guilty of a crime. For accidents or crimes that involved radioactive substances unbeknownst to those involved, see the Nuclear and radiation accidents and incidents. Murder and attempted murder The Karlsruhe plutonium affair Johannes M. was convicted of attempting to poison his ex-wife in 2001 with plutonium stolen from WAK (Wiederaufbereitungsanlage Karlsruhe), a small scale reprocessing plant where he worked. He did not steal a large amount of plutonium, only rags used for wiping surfaces and a small amount of liquid waste. At least two people (besides the criminal) were contaminated by the plutonium. Two flats in Landau in the Rhineland-Palatinate were contaminated, and had to be cleaned at a cost of two million euro. Photographs of the case and details of other nuclear crim ...

Radiation Warning Symbol
Hazard symbols are universally recognized Symbol, symbols designed to alert individuals to the presence of Hazard, hazardous or dangerous materials, locations, or conditions. These include risks associated with Electromagnetic field, electromagnetic fields, Electrical injury, electric currents, toxic chemicals, Explosive, explosive substances, and Radioactivity, radioactive materials. Their design and use are often governed by laws and standards organizations to ensure clarity and consistency. Hazard symbols may vary in color, background, borders, or accompanying text to indicate specific dangers and levels of risk, such as toxicity classes. These symbols provide a quick, universally understandable visual warning that transcends language barriers, making them more effective than text-based warnings in many situations. List of standardized hazard symbol systems Examples of common symbols Tape with yellow and black diagonal stripes is commonly used as a generic hazard warni ...

Cesium-137
Caesium-137 (), cesium-137 (US), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from spontaneous fission of uranium-238. It is among the most problematic of the short-to-medium-lifetime fission products. Caesium-137 has a relatively low boiling point of and easily becomes volatile when released suddenly at high temperature, as in the case of the Chernobyl nuclear accident and with atomic explosions, and can travel very long distances in the air. After being deposited onto the soil as radioactive fallout, it moves and spreads easily in the environment because of the high water solubility of caesium's most common chemical compounds, which are salts. Caesium-137 was discovered by Glenn T. Seaborg and Margaret Melhase. Decay Caesium-137 has a half-life of about 30.04 year ...

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] |
Oklahoma
Oklahoma ( ; Choctaw language, Choctaw: , ) is a landlocked U.S. state, state in the South Central United States, South Central region of the United States. It borders Texas to the south and west, Kansas to the north, Missouri to the northeast, Arkansas to the east, New Mexico to the west, and Colorado to the northwest. Partially in the western extreme of the Upland South, it is the List of U.S. states and territories by area, 20th-most extensive and the List of U.S. states and territories by population, 28th-most populous of the 50 United States. Its residents are known as Oklahomans and its capital and largest city is Oklahoma City. The state's name is derived from the Choctaw language, Choctaw words , 'people' and , which translates as 'red'. Oklahoma is also known informally by its List of U.S. state and territory nicknames, nickname, "The Sooner State", in reference to the Sooners, American pioneer, American settlers who staked their claims in formerly American Indian-o ...

Plutonium-239
Plutonium-239 ( or Pu-239) is an isotope of plutonium. Plutonium-239 is the primary fissile isotope used for the production of nuclear weapons, although uranium-235 is also used for that purpose. Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and uranium-233. Plutonium-239 has a half-life of 24,110 years. Nuclear properties The nuclear properties of plutonium-239, as well as the ability to produce large amounts of nearly pure 239Pu more cheaply than highly enriched weapons-grade uranium-235, led to its use in nuclear weapons and nuclear power plants. The fissioning of an atom of uranium-235 in the reactor of a nuclear power plant produces two to three neutrons, and these neutrons can be absorbed by uranium-238 to produce plutonium-239 and other isotopes. Plutonium-239 can also absorb neutrons and fission along with the uranium-235 in a reactor. Of all the common nuclear fuels, 2 ...

Karen Silkwood
Karen Gay Silkwood (February 19, 1946 – November 13, 1974) was an American laboratory technician and labor union activist known for reporting concerns about corporate practices related to health and safety in a nuclear facility. She worked at the Kerr-McGee Cimarron Fuel Fabrication Site in Crescent, Oklahoma, making plutonium pellets. She was the first woman ever elected to the union's negotiating team at Kerr-McGee. After testifying to the Atomic Energy Commission about her safety concerns, she was found to have plutonium contamination in her body and her home. While driving to meet with a ''New York Times'' journalist and an official of her union's national office, she died in a car crash, the circumstances of which were never explained entirely. Her family sued Kerr-McGee for the plutonium contamination that Silkwood suffered from. The company settled out of court for US$1.38 million, while not admitting liability. Her story was chronicled in Mike Nichols's 198 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labor Union
A trade union (British English) or labor union (American English), often simply referred to as a union, is an organization of workers whose purpose is to maintain or improve the conditions of their employment, such as attaining better wages and Employee benefits, benefits, improving Work (human activity), working conditions, improving safety standards, establishing complaint procedures, developing rules governing status of employees (rules governing promotions, just-cause conditions for termination) and protecting and increasing the bargaining power of workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called ''union dues''. The union representatives in the workforce are usually made up of workplace volunteers who are often appointed by members through internal democratic elections. The trade union, through an elected leadership and bargaining committee, bargains with the employer on behalf of its members, known as t ...

Kerr-McGee
The Kerr-McGee Corporation, founded in 1929, was an American energy company involved in oil exploration, production of crude oil, natural gas, perchlorate and uranium mining and milling in various countries. On June 23, 2006, Anadarko Petroleum acquired Kerr-McGee in an all-cash transaction totalling $16.5 billion plus $2.6 billion in debt and all operations moved from their base in Oklahoma, United States. As a result of further acquisitions, most of the former Kerr-McGee is now part of Occidental Petroleum. History The company later known as Kerr-McGee was founded in 1929 as Anderson & Kerr Drilling Company by Oklahoma businessman-politician Robert S. Kerr (1896-1963) and oil driller James L. Anderson. When Dean A. McGee (1904-1989), a former chief geologist for Phillips Petroleum, joined the firm in 1946, it changed its name to Kerr-McGee Oil Industries, Incorporated. The company initially focused mostly on off-shore oil exploration and production, being one of the first com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiation Sickness
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. Symptoms can start within an hour of exposure, and can last for several months. Early symptoms are usually nausea, vomiting and loss of appetite. In the following hours or weeks, initial symptoms may appear to improve, before the development of additional symptoms, after which either recovery or death follows. ARS involves a total dose of greater than 0.7 Gy (70 rad), that generally occurs from a source outside the body, delivered within a few minutes. Sources of such radiation can occur accidentally or intentionally. They may involve nuclear reactors, cyclotrons, certain devices used in cancer therapy, nuclear weapons, or radiological weapons. It is generally divided into three types: bone marrow, gastrointestinal, and neurovascular syndrome, with bone m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
