What is Iridium 192 Radiation
Iridium 192 (symbol 192Ir) is a kind of a radioactive isotope iridium with a half of life of 73.83 days. It gets decomposed by sending out beta (β) particles and gamma (γ) radiation. About 96% of 192 Ir decomposition takes place through emission of β and γ radiation, resulting into 192Pt. Iridium 192 is also an emitter of gamma ray. There are seven main energy packets created during its disintegration process spanning from just over 0.2 to about 0.6 MeV. Iridium-192 is basically utilized as a strong gamma ray source in industrial radiography to find out flaws in metal components. It is also employed in radiotherapyas a radiation source, particularly in brachytherapy.
The Applications of Iridium 192 Tungsten Radiation Shielding
Because of its greater density, outstanding absorption capacity against radiation, besides being environment-friendly, tungsten alloy can be extensively applied to create Iridium 192 tungsten radiation shielding. Iridium 192 tungsten radiation shielding can be utilized to store Iridium 192 radioactive source, that can be applied in Iridium 192 gamma detection machine. Since the gamma-ray energy of Iridium 192 is normal with highly specific activity of radioactive sources, and under the general thickness, Iridium 192 gamma detection machine possesses an excellent detection sensitivity.This detector does not require a power supply, cooling water, exposure to small size, very advantageous for on-site and field application. Iridium 192 tungsten radiation shielding is primarily applied for oil pipelines, wells and other critical structural flaw, as well as radiation therapy for cancer, and pressure vessel, weld inspection such as spherical tanks.
The Advantages of Iridium 192 Tungsten Radiation Shielding
In comparision to conventional radiation shielding materials encompassing boron carbide and lead, tungsten alloy radiation bricks assures of outstanding density with little strength. Tungsten Alloy Radiation Brick with same weight and better density can offer the same energy absorption as lead does through using 1/3 less material. At the time of designing Shielding, tungsten alloy radiation shielding is measured in accordance with necessity of shield to cut down the multiple thickness of shielding materials.
