Dose Evaluation of the Man Adjacent to an Implanted Patient During the Prostate Cancer Brachytherapy = 전립선암의 근접치료 시 이식환자에 근접한 사람의 선량평가

국문 초록 (Abstract)

본 연구는 전립선암의 치료방법 중 근접치료 시 환자 주변의 공간에 대한 선량을 평가한 것으로 환자, 시술자 그리고 보호자에 대한 선량을 예측함으로서 피폭을 최소한으로 예방하고자 수행하였다. 실험방법 은 몬테칼로법을 기반으로 한 MCNPX를 사용하여 가상의 공간에서 모의피폭체를 만들어 실험하였으며, 선원은 192 Ir, 125 I, 103 Pd를 seed 형태로 이식하였다. 환자를 중심으로 전방 30, 50, 100, 200 ㎝ 거리에 관심영역을 설정하여 공간 선량을 평가하였다. 그 결과 거리에 관계없이 192 Ir에서 가장 높은 선량을 나타내었다.

다국어 초록 (Multilingual Abstract)

This study is fulfilled to evaluate the exposure dose nearby a patient during the brachytherapy of the prostate cancer treatment and to minimize the radiation exposure by evaluating the exposure dose of the person near the relevant implanted patient, technicians and gardians. The experiment method is used on the study is MCNPX that is stood on the basis monte-carlo method and implant the source to MIRD-type phantom in 192 Ir, 125 I, and 103 Pd in virtual space. For dose evaluations according to distance, the radiation dose on the patient near the corresponding implanted patient is evaluated by each distance of 30, 50, 100, 200 cm to anterior from the implanted patient. As a result, 192 Ir showed a higher dose than 125 I and 103 Pd in every distance.
