ISO 21482
ISO 21482 is a technical standard that specifies the design and usage of a "supplemental radiation warning symbol", a hazard symbol, warning symbol. It is intended to warn people of the dangers of radioactive decay, radiation hazards posed by Radioactive source, sealed sources, and encourage the viewer to get away from the source. The symbol's design was the result of a joint project between the International Atomic Energy Agency (IAEA) and International Organization for Standardization (ISO) in the early 2000s. The symbol was formally revealed to the public by the IAEA on 15 February 2007. Background Lost nuclear sources, or "orphan sources" have presented a hazard to the public dating from at least the early 1960s. These often originated from larger equipment being dismantled by individuals in search of metal for scrap. Even the source itself, often contained in a metal housing that can appear valuable. In the aftermath of repeated incidents where the public was exposed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skull And Crossbones
A skull and crossbones is a symbol consisting of a human skull and two long bones crossed together under or behind the skull. The design originated in the Late Middle Ages as a symbol of death and especially as a ''memento mori'' on tombstones. In modern contexts, it is generally used as a hazard symbol that warns of danger, usually in regard to poisonous substances, such as deadly chemicals. It is also associated with piracy and software piracy, due to its historical use in some Jolly Roger flags. Military use The skull and bones are often used in military insignia, such as the coats of arms of regiments. Symbol for poisonous substances The skull and crossbones has long been a standard symbol for poison. In 1829, New York State required the labeling of all containers of poisonous substances. The skull and crossbones symbol appears to have been used for that purpose since the 1850s. Previously a variety of motifs had been used, including the Danish "+ + +" and drawi ...

Trefoil
A trefoil () is a graphic form composed of the outline of three overlapping rings, used in architecture and Christian symbolism, among other areas. The term is also applied to other symbols with a threefold shape. A similar shape with four rings is called a quatrefoil. Architecture Ornamentation 'Trefoil' is a term in Gothic architecture given to the ornamental foliation or cusping introduced in the heads of window-lights, tracery, and panellings, in which the centre takes the form of a three-lobed leaf (formed from three partially overlapping circles). One of the earliest examples is in the plate tracery at Winchester Cathedral (1222–1235). The fourfold version of an architectural trefoil is a quatrefoil. A simple trefoil shape in itself can be symbolic of the Trinity, while a trefoil combined with an equilateral triangle was also a moderately common symbol of the Christian Trinity during the late Middle Ages in some parts of Europe, similar to a barbed quatrefoil.

Logo Iso Radiation
A logo (abbreviation of logotype; ) is a graphic mark, emblem, or symbol used to aid and promote public identification and recognition. It may be of an abstract or figurative design or include the text of the name it represents as in a wordmark. In the days of hot metal typesetting, a logotype was one word cast as a single piece of type (e.g. "The" in ATF Garamond), as opposed to a ligature, which is two or more letters joined, but not forming a word. By extension, the term was also used for a uniquely set and arranged typeface or colophon. At the level of mass communication and in common usage, a company's logo is today often synonymous with its trademark or brand.Wheeler, Alina. ''Designing Brand Identity'' © 2006 John Wiley & Sons, Inc. (page 4) Etymology Douglas Harper's Online Etymology Dictionary states that the term 'logo' used in 1937 "probably a shortening of logogram".

Vienna International School
Vienna International School (VIS) is a non-profit international school in Vienna, Austria. The school was built to accommodate the children of United Nations (UN) employees and diplomats when the UN decided to locate one of its offices in Vienna (at the Vienna International Centre), and it remains affiliated to the UN. About 50% of students are children of UN employees and receive education grants, while much of the remaining students are children mainly of embassy staff and company staff. The school has an enrollment of 1400 students, from pre-primary to twelfth grade. History International Community School The first English language medium school in Vienna was set up in August 1955 as the International Community School. Previously, it had been the 'British Army School' in Schönbrunn barracks and catered for the children of the British occupying forces in Vienna.

Radioactive
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay ( ), beta decay ( ), and gamma decay ( ), all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetism and nuclear force. A fourth type of common decay is electron capture, in which an unstable nucleus captures an inner electron from one of the electron shells. The loss of that electron from the shell results in a cascade of electrons dropping down to that lower shell resulting in emission of discrete X-rays from the transitions. A common example is iodine-125 commonly used in medical settings. Radioactive decay is a stochastic (i.e. random) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goiânia Accident
The Goiânia accident was a radioactive contamination accident that occurred on September 13, 1987, in Goiânia, Goiás, Brazil, after a forgotten radiotherapy source was stolen from an abandoned hospital site in the city. It was subsequently handled by many people, resulting in four deaths. About 112,000 people were examined for radioactive contamination and 249 of them were found to have been contaminated. In the consequent cleanup operation, topsoil had to be removed from several sites, and several houses were demolished. All the objects from within those houses, including personal possessions, were seized and incinerated. ''Time'' magazine has identified the accident as one of the world's "worst nuclear disasters" and the International Atomic Energy Agency (IAEA) called it "one of the world's worst radiological incidents". Description of the source The radiation source in the Goiânia accident was a small capsule containing about of highly radioactive caesium c ...
