Abstract
In this study, natural iridium consisting of Ir-191 and Ir-193 isotopes has been irradiated with 21 MeV photons. The distribution of photons, electrons and neutrons fluxes in the spherical and cylindrical natural iridium target have been calculated using MCNPX 2.7.0 Monte Carlo code. The intensity of the photon fluxes on both targets has been compared to the 106 particle story by showing them as mesh and optimizing the two targets.

Summary
Nowadays particle beams are produced by tens of thousands of accelerators in various fields such as hospitals, manufacturing and printing plants, industrial laboratories, ports. The radionuclides have been generally used at nuclear medicine for diagnostic purposes of some diseases as well as in therapy [2,3]. The basic component of photonuclear radioisotope production by linear electron accelerators (LINACs) is a bremsstrahlung converter. A high Z photon converter which is made of tantalum (Ta) or tungsten (W) absorbs the high-energy electrons produced by LINAC. Nuclear data are needed in many applications which energy related investigations are fusion [5,6,7,8], fission, accelerator driven systems, etc. Natural iridium targets with two different geometries have irradiated with photon beam of 21 MeV energy produced from a linear accelerator by using Monte Carlo simulations
