تولید ایریدیوم-192 در سازمان انرژی اتمی ایران برای مصارف براکی تراپی

          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).
