Abstract: With increased demand for low ¹⁰³Pd (palladium) seed sources, to treat prostate and eye cancers, new sources have been designed and introduced. This paper presents the two new palladium brachytherapy sources, IR03-¹⁰³Pd and IR04-¹⁰³Pd that have been developed at Agricultural, Medical & Industrial Research School. The dosimetric parameters, such as the dose rate constant &923;, the radial dose function g(r) and the anisotropy function F(r, θ), around the sources have been characterised using Version 5 Monte Carlo radiation transport code in accordance with the update AAPM Task Group No. 43 Report (TG-43U1). The results indicated the dose rate constant of 0.689 ± 0.02 and 0.667 ± 0.02 cGy h⁻¹ U⁻¹ for the IR03-¹⁰³Pd and IR04-¹⁰³Pd sources, respectively, which are in acceptable agreement with other commercial seeds. The calculated results were compared with published results for those of other source manufacturers. However, they show an acceptable dose distribution, using for clinical applications is pending experimental dosimetry.
