放射線治療時の生殖腺被曝線量(第5報) : 良性皮膚疾患患者の生殖腺被曝線量

抄録

It is said that the gonadal dose of patients at the time of superficial x-ray treatment is less than other radiation. But as the diseases are nonmaligant, gonadal dose is not always negligible. I tried to determine the gonadal dose by the measurement of the phantom experiment. Dose measurement were performed by using of the Philips Universal Dosimeter, GM Survey Meter and Film Density Method. The majority of lesions with superficial x-ray were head and neck areas. The average treatment dose was 900R. The gonadal dose of female patients treated hypogastric area was found 6.5R from the results of phantom experiment. But gonadal doses of other regions of female patients were found less than 10mR. The gonadal dose of the male patient irradiated scrotum was 55.6R. But it was between the 1.5R and 130mR at the regions other than head, neek. feet and fingers.
