Evaluation of two thermoluminescent detection systems for medical imaging environments.
Thermoluminescent detectors (TLDs) can provide accurate and precise measurements for both patient and personnel dosimetry in the medical imaging environment. They have the advantages of tissue equivalency, an excellent dynamic range, and dose rate independence. In the work reported here, experiments with planar x-ray, fluoroscopy, and a 57Co source were conducted to test the repeatability and energy dependence of an LiF TL ribbon/automatic reader system and a four-element CaSO2 and Li2B4O7 badge/automatic reader system for diagnostic radiology and nuclear medicine dosimetry. The results indicate the usefulness and appropriateness of the TLD systems tested for both personnel and patient dosimetry in the medical diagnostic environment.
