The Production of Iridium-192 for Brachytherapy in Iran Atomic Energy Agency

Iridium-192 is one of the radioactive materials used in Brachytherapy in the treatment of tongue, lip, skin, prostate, breast and brain cancers. Different forms of Iridium-192 are used in Brachytherapy. This study was performed in order to produce Iridium-192 for the above mentioned uses in Iran. This research was carried out on two kinds of Iridium-192 wire using facilities available at the Iranian Atomic Energy organization. Activation of wire was done based on standards for employing Brachytherapy in the atomic reactor of the Iranian Atomic Energy Organization. In this study Kerma scan system was used to examine the properties of the materials. Results of this study showed that thermal neutron flux, geometric position of wire model during thermal neutron flux and sample constancy when activating wires by neutron radiation play a fundamental role in the activity homogeneity of the sample wire lengh and its activities. Regarding the results, iridium-192, can be produced for Brachytherapy uses in the Iran Atomic Energy Organization. At present this material is employed in Brachytherapy in the institute of cancer and Jorjani hospital (Tehran).
