In radiation for malignant tumor, interstitial irradiation and/or intracavitary irradiation are performed in addition to external irradiation. The former two treatments are well applied for the tumors at head and neck region, especially carcinoma of the tongue and for that in gynecological tumor like carcinoma of the cervix. However, nurses are supposed to be irradiatated during the treatment, as they help the handing of radiation sourses to insert or to pierce them directly into diseased parts. In this paper, we measured the relationship between working time of nurses for the treatment and exposure doses of nurses, using a thermoluminescence dosimeter. the exposure doses were approximately proportional to the working time, and 3-6 mR working time for a treatment in the cases of the diseases head and neck, and 4 mR working time for a treatment in the cases of gynecological diseases.
