Abstract:
The ?-radioactive seed brachytherapy source has been widely employed in the implantation therapy for the prostatic carcinoma and the ophthalmic lesions.In this study the dosimetric parameters for characterization of a low-energy interstitial brachytherapy source 125I were calculated according to dose calculation formalism recommended by AAPM TG-43U1.For data processing,a 0.28 cm active length was used for the geometry function.The dosimetry parameter air-Kerma strength,dose rate constant,radial dose function and anisotropy function were estimated by means of the EGS5 Monte Carlo code.The results obtained from this study are in good agreement with the corresponding values recommended by TG-43U1 and with the data reported by Dolan,et al.
