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).
