An assessment of lithium borate thermoluminescent dosimeters for the measurement of doses to patients in diagnostic radiology. 1976

W A Langmead, and B F Wall

A pilot survey of doses to patients undergoing four types of radiological procedure--barium enemas, intravenous pyelography, cardiac catheterization and mammography--has been made using lithium borate TL dosimeters. The survey was designed to test the operational suitability of the dosimetry system and to gain experience and gather data for the planning of further larger surveys. The TL dosimeters were calibrated against conventional ionization chambers, and then used on patients for determining gonad doses and maximum doses to the skin. Few difficulties were encountered in using the system. The measured doses to patients have been compared with previous determinations by other authors and reasonable agreement demonstrated.

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).
