One source can be used for a longer period of time, and can be applied for multiple patients. At that point the source in the afterloader will have to be replaced. This means that after 74 days only half of the Ir-192 is left in the radiation source. The doctor (radiotherapist) uses a special machine to perform the treatment safely this machine is the afterloader. In the hospital the sources are applied in brachytherapy to treat cancer. This is how the isotopes find their way across the world via Curium. Curium sends the Ir-192 sources to its customers, the producers of afterloaders also known as the suppliers of brachytherapy solutions. On the same site in Petten, NRG’s customer Curium process the radioactive Ir-192 into sources: metal parts the size of a grain of rice. The most important iridium compounds in use are the salts and acids it forms with chlorine, though iridium also forms a number of organometallic compounds used. It is widely used in anode catalysts for PEM electrolyzers, which are needed to. NRG can guarantee the required quality thanks to extensive experience in Ir-192 production and thanks to our direct access to the correct and safe nuclear infrastructure. Iridium has catalytic properties which make it suitable for hydrogenation. The modulus of elasticity of this metal is also very high as compared to other elements. The density of iridium is 22.56g/cm3, which makes it the densest metal after osmium. In the medical world, iridium-192 is most commonly used to fight cancer cells. At the temperature below 0.14K, this element becomes a superconductor. It is a gamma emitter and has a half-life of 74 days. Brachytherapy is a therapy that requires great accuracy of the isotope being used. The boiling point of iridium is 4428☌, the tenth highest among all the elements.
