Western Australian Radioactive Capsule Incident
Sometime between 10 and 16 January 2023, a radioactive capsule containing caesium-137 was lost from a truck in Western Australia. The capsule was being transported from Rio Tinto's Gudai-Darri iron ore mine near Newman to a depot in the Perth suburb of Malaga. The Department of Fire and Emergency Services announced to the public on 27 January that the capsule had gone missing, and that the capsule was potentially deadly and could cause burns and radiation sickness. It was discovered on the side of the road near Newman on 1 February. The capsule The capsule is in size, and is used as part of a nucleonic level sensor in the crushing circuit in iron ore mining. The capsule contains 19 gigabecquerel of caesium-137 as a ceramic source. The amount of radiation emitted by the capsule could induce burns and radiation sickness and is potentially deadly to humans. Timeline On 10 January 2023, the capsule was packed in order for repair works to be carried out in Perth. Betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Northern Highway
Great Northern Highway is an Australian highway that links Western Australia's capital city Perth with its northernmost port, Wyndham. With a length of almost , it is the longest highway in Australia, with the majority included as part of the Perth Darwin National Highway. The highway is constructed as a sealed, predominantly two-lane single carriageway, but with some single-lane bridges in the Kimberley. The Great Northern Highway travels through remote areas of the state, and is the only sealed road link between the Northern Territory and northern Western Australia. Economically, it provides vital access through the Wheatbelt and Mid West to the resource-rich regions of the Pilbara and Kimberley. In these areas, the key industries of mining, agriculture and pastoral stations, and tourism are all dependent on the highway. In Perth, the highway begins in Midland near Great Eastern Highway, and further north intersects the Reid and Roe highways, which together form Perth's ...

Caesium
Caesium ( IUPAC spelling) (or cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of , which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. It is pyrophoric and reacts with water even at . It is the least electronegative element, with a value of 0.79 on the Pauling scale. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite. The element has 40 known isotopes, making it, along with barium and mercury, one of the elements with the most isotopes. Caesium-137, a fission product, is extracted from waste produced by nuclear reactors. The German chemist Robert Bunsen and physicist Gustav Kirchhoff discovered caesium in 1860 by the newly developed method of flame spectroscopy. The first small-scale applications fo ...

2020s In Western Australia
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the complica ... [...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 ...

Kramatorsk Radiological Accident
The Kramatorsk radiological accident was a radiation accident that happened in Kramatorsk, in the Ukrainian SSR from 1980 to 1989. A small capsule containing highly radioactive caesium-137 was found inside the concrete wall of an apartment building, with a surface gamma radiation exposure dose rate of 1800 R/year. The capsule was detected only after residents requested that the level of radiation in the apartment be measured by a health physicist. The capsule was originally part of a radiation level gauge and was lost in the Karansky quarry in the late 1970s. The search for the capsule was unsuccessful and ended after a week. The gravel from the quarry was used in construction. The caesium capsule ended up in the concrete panel of apartment 85 of building 7 on Mariyi Pryimachenko Street (at the time under the Soviet name Gvardeytsiv Kantemirovtsiv), between apartments 85 and 52. Over nine years, two families lived in apartment 85. A child's bed was located directly next t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
