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 ...
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 ...

is not widely used for industrial radiography as other nuclides, such as cobalt-60 or iridium-192, offer higher radiation output for a given volume. Iodine-131 is another important gamma-emitting radionuclide produced as a fission product. With a short half-life of 8 days, this radioisotope is not of practical use in radioactive sources in ...

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 ...
Common source radionuclides include cobalt-60, [1] iridium-192, [2] and strontium-90. [3] The SI measurement quantity of source activity is the Becquerel, though the historical unit Curies is still in partial use, such as in the US, despite their NIST strongly advising the use of the SI unit. [4] The SI unit for health purposes is mandatory in ...
