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 ...

This infobox contains the table of § Main isotopes, and the § Standard atomic weight. For example, {{Infobox uranium isotopes}}, as used on page Isotopes of uranium. The main isotopes table is reused in the regular Infobox: {{Infobox uranium}}.
A material's half-value layer (HVL), or half-value thickness, is the thickness of the material at which the intensity of radiation entering it is reduced by one half. [1] HVL can also be expressed in terms of air kerma rate (AKR), rather than intensity: the half-value layer is the thickness of specified material that, "attenuates the beam of radiation to an extent such that the AKR is reduced ...
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.

This value is in the denominator of the decay correcting fraction, so it is the same as multiplying the numerator by its inverse (), which is 2.82. (A simple way to check if you are using the decay correct formula right is to put in the value of the half-life in place of "t".
