Abstract
With increased demand for low 103 Pd (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- 103 Pd and IR04- 103 Pd that have been developed at Agricultural, Medical & Industrial Research School . The dosimetric parameters, such as the dose rate constant Λ , 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- 103 Pd and IR04- 103 Pd 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.
期刊介绍:
The IJLR is a peer-reviewed journal dedicated to the publication of research articles, review papers and technical notes in all domains related to low-dose radiation, among which are the biological and health effects in humans and the biota, in vitro and in vivo research on low radiation effects, regulatory and policy aspects, risk estimation and public perception.
