X-ray beam qualities of 72-118 kVp with HVT's of 0.66-3.9 mm A1 were used to irradiate three head phantoms constructed from the skulls of 3-, 6-, and 12-year-old children using Mix D as soft tissue equivalent material. Thermoluminescent dosimeters were used for 'in phantom' exposure measurements. A relatively simple method was developed which yields an accurate estimation of dose distribution in the brain and doses to the eye and thyroid of children (ages 3-12) irradiated with any x-ray technique commonly employed for the treatment of tinea capitis. Typical ranges of doses to the organs of the head are: brain, 100-200 rads; lens of eye, 10-25 rads; and thyroid, 2-5 rads. (Author)
