Abstract
Abstract The main properties of a new thermoluminescent (TL) material (LiF:Cu,Mg,P) produced in the People's Republic of China under the name of GR-200A have been already investigated by others. The purpose of this work is to establish a standardised procedure for use. Careful experiments were carried out with the aim of identifying the optimal annealing cycle and the dependence of TL sensitivity on the heating rate. Further more, reading procedure, fading, calibration and TL dependence on dose were studied along with other relevant physical features. The high sensitivity (20 to 30 times that of LiF TLD-100), the wide range of dose linearity (0-18 Gy), the short annealing procedure (10 min. at 513 k) together with a negligible fading at room temperature, quick readout cycle (35 s), good tissue-equivalence (Zeff=7-8) and TL signal reproducibility (SD <2.5%) make GR-200A TLDs particularly valuable for several dosimetry purposes. Their high sensitivity makes them especially eligible for environmental and radiological dosimetry, while the wide dose linearity range allows various radiotherapeutic applications in patient and machinery output dosimetry.
