![]() ![]() It is also used for medical treatment, such as for the cure of stomal recurrence after Tracheostomy is performed for subglottic carcinoma. High-dose rate (HDR) Iridium-192 Brachytherapy is often facilitated with the aid of a flexible applicator. ![]() In case of an accidental exposure, victims should remove clothes and discard them permanently. It should be kept safe in order to avoid accidental exposure or deliberate misuse and disposed following state guidelines. Iridium-192 Radiation Safetyīeing a radioactive substance, necessary safeguards must be taken while using it. As a result, high concentration of 192Ir is produced comparatively easily. It ensures minimal generation of unwanted isotopes and large cross section of isotopes for interaction of neutrons. Iridium-192 Productionįor commercial use, 192Ir is produced in a nuclear reactor by reaction of 191Ir with neutrons. For applications of high dose, its specific activity is 2.4×102 TeV/g. Its specific activity differs depending on the concentration of 192Ir in the source. Consequently, the use of radon and radium decreased. Once World War II ended, new isotopes such as cobalt-60, caesium-137 and iridium-192 became available for Industrial Radiography. It is also the most common isotope used for high dose rate brachytherapy applications. Iridium-192 IsotopesĪs aforesaid, Iridium-192 is a radioactive iridium isotope. A gamma photon with an average energy of 0.38 MeV (max 1.06 MeV) is released in the process. For the remaining 4.87% of the time, it decays through electron capture to 192Os. It decays 95.13% of the time through negative beta emission to 192Pt (daughter nuclide). Its decay modes are Beta Particles and Gamma Radiation. The lifetime of this radioactive element is 106.51 days. The half-life of this isotopic substance is 73.828 days. It has a mass excess of -34.833207 MeV(Megaelectronvolts).The atomic mass of this radioactive substance is 191.962605012 u (unified atomic mass units).The atomic number of this element is 77.The mass number of this radioactive element is 192.Know about some important facts associated with this substance. It is a dense metal and has a relative density of 22.42.Its specific gravity is 22.562 (at 20☌). ![]()
