摘要

Hysterosalpingography (HSG) is a useful and widely employed technique which uses X-ray fluoroscopy torninvestigate the female genital tract. Fluoroscopy is assessed by a gynaecologist, a physician who is not alwaysrntrained to work with ionising radiation. Dose-area product measurements in a group of 34 patients allowed anrnestimation of the median effective dose (0,83 mSv) and the median dose to the ovaries (1,63 mGy) of the patientrnper procedure. The dose to the staff was estimated using thermoluminescent dosimetry. The following medianrnentrance surface doses were estimated per procedure: 0,22 mGy to the lens of the eye, 0,15 mGy to the neck atrnthyroid level and 0,19 mGy to the back of the hand. The annual eye dose limit could be exceeded if therngynaecologist is a member of the public.
