[Thermoluminescent dosimetry for radiation exposure of the breast during film and xeromammography (author's transl)]. 1978

M Säbel, and A Ruff, and J Weishaar

Measurements of radiation exposure of the breast during various mammographic procedures were carried out with LiF dosimeters. Using non-screen film (Kodak Definix Medical) at 30 kv., average skin dose in 105 patients was 10.1 R per exposure. During xeroradiography (45 kv.) skin dose was about 25% of this and for a film-screen system (Mammoray RP 3/MR 50 at 30 kv.) only 7% of this value. Skin dose (at constant potential) rises almost exponentially with increasing tissue thickness. The age of the patient and the type of tissue in the breast has a significant effect on the radiation dose. From the measurements, an average dose per exposure was calculated for the entire breast and for the glandular tissue. This gave a result of 1.6 rd (16 mGy) and 1.0 rd (10 mGy).

D011829	Radiation Dosage	The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).

D013819	Thermoluminescent Dosimetry	The use of a device composed of thermoluminescent material for measuring exposure to IONIZING RADIATION. The thermoluminescent material emits light when heated. The amount of light emitted is proportional to the amount of ionizing radiation to which the material has been exposed.
