| 内容記述 | Since the authorization of brachytherapy using 125I seeds for prostate cancer treatment in 2002 in Japan, the number of this procedure has been increasing. While this procedure has shown its effectiveness, it has been suspected that frequent operations by a single surgeon might cause over-exposures. To ensure surgeon's safety from the viewpoint of radiation protection, we conducted the measurements of surface doses of medical personnel during the procedures. The measurements were performed with TLDs and glass dosemeters applied to various points of the surgeon during 125I brachytherapy operations. The sensitivities of those dosemeters were calibrated for photon beam at corresponding energy (approximately 30 keV). The results of the measurements repeated for 20 times since February 2007 to May 2008 at a hospital showed surface doses on the surgeon ranged up to 650 uGy. They were far below the dose level causing deterministic effects on the skin. It was also shown that utilization of protective gloves (Pb 0.03 mm equivalent) reduced the doses to hands effectively. The surface doses of a surgeon tended to decrease possibly due to improved proficiency during the series of measurements. As a conclusion, the annual accumulated dose is not likely to reach the dose limit if sufficient attention is paid to radiation protection like these studied cases. | |||||
