Iridium-192 (symbol 192 Ir) is a radioactive isotope of iridium, with a half-life of 73.827 days. [1] It decays by emitting beta (β) particles and gamma (γ) radiation. About 96% of 192 Ir decays occur via emission of β and γ radiation, leading to 192 Pt. Some of the β particles are captured by other 192 Ir nuclei, which are then converted ...
1971 – Chiba, Japan – a 5.26 Ci (195 GBq) iridium-192 source used for industrial radiography was lost. Six construction workers received doses of 15–130 rem (0.15–1.30 Sv). [5] January 8, 1977 – Sasolburg, Free State, South Africa – a 6.7 Ci (250 GBq) iridium-192 source fell out of its container at a construction site. The ...
An urban legend, myth, or tale is a modern genre of folklore. It often consists of fictional stories associated with the macabre, superstitions, ghosts, demons, cryptids, extraterrestrials, creepypasta, and other fear generating narrative elements. Urban legends are often rooted in local history and popular culture
In March 1984, a serious radiation accident occurred in Morocco, at the Mohammedia power plant, where eight people died from pulmonary hemorrhaging caused by overexposure to radiation from a lost iridium-192 source. [1] Other individuals also received significant overdoses of radiation that required medical attention.
192 Ir, which falls between the two stable isotopes, is the most stable radioisotope, with a half-life of 73.827 days, and finds application in brachytherapy [28] and in industrial radiography, particularly for nondestructive testing of welds in steel in the oil and gas industries; iridium-192 sources have been involved in a number of ...
Iridium-192 (symbol 192 Ir) is a radioactive isotope of iridium, with a half-life of 73.83 days. [11] It decays by emitting beta (β) particles and gamma (γ) radiation. About 96% of 192 Ir decays occur via emission of β and γ radiation, leading to 192 Pt. Some of the β particles are captured by other 192 Ir nuclei, which are then converted ...
Cobalt-60 tends to be used in teletherapy units as a higher photon energy alternative to caesium-137, while iridium-192 tends to be used in a different mode of therapy, internal radiotherapy or brachytherapy. The iridium wires for brachytherapy are a palladium-coated iridium/palladium alloy wire made radioactive by neutron activation.
The Red Room Curse (Japanese: 赤い部屋, Hepburn: Akai heya) is an early Japanese Internet urban legend about a red pop-up ad which announces the forthcoming death of the person who encounters it on their computer screen. [1] It may have its origin in an Adobe Flash horror animation of the late 1990s that tells the story of the legend. [2]
