Abstract Objective To measure the exposure doses to the personel after implanting Iodine-125 seeds into the simulated human-body,phantom.Methods The exposure dose rates were detected by FD3101 gamma-dosimeter at the phantom surface and the locations at 30 cm and 100 cm from the phantom,respectively.Extensive dose equvalent measurements were performed at various organ locations in the phantom,using TLD dosimeters.Results All results were listed in table 1and table 2.Conclusion Exposure doses have been measured and calculated after Iodine-125 seeds implant.They are much lower than those presented in national standards.it is believed that Iodine-125 seeds permanent interstitial implant is promising radiotherapeatic application.
