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 ...
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 ...
It has a half-life of 30 years, and decays by beta decay without gamma ray emission to a metastable state of barium-137 (137m Ba). Barium-137m has a half-life of a 2.6 minutes and is responsible for all of the gamma ray emission in this decay sequence. The ground state of barium-137 is stable. The photon energy (energy of a single gamma ray) of ...
Unstable isotopes decay through various radioactive decay pathways, most commonly alpha decay, beta decay, or electron capture. Many rare types of decay, such as spontaneous fission or cluster decay, are known. (See Radioactive decay for details.) [citation needed] Of the first 82 elements in the periodic table, 80 have isotopes considered to ...

Radionuclides are chosen according to the type and character of the radiation they emit, intensity of emission, and the half-life of their decay. Common source radionuclides include cobalt-60, [1] iridium-192, [2] and strontium-90. [3]

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 ...
