Abstract
A glow curve measurement apparatus of TLDs with a constant heating rate and a wide measurable range has been developed to study the characteristics of TLDs and to apply them to synchrotron radiation dosimetry. The heating rates of 0.5, 1, 2, 3, and 5 degC/s are controlled within an accuracy of {+-} 2 % from room temperature up to 450degC and the TL output corresponding to the photomultiplier current from 0.01 nA to 100 {mu}A can be measured as digital values per every 1 msec through a current digitizer, in which the linearity of the current digitizer is guaranteed with an accuracy less than 0.1 %. The glow curve and the dose response of LiF, Li{sub 2}B{sub 4}O{sub 7} (Mn), and Li{sub 2}B{sub 4}O{sub 7} (Cu) TLDs have been measured for {sup 60}Co gamma-rays and synchrotron radiations of 10 to 40 keV up to a couple of 10{sup 3} Gy using the present system. Apparent differences among the glow curves and the dose responses have been observed with respect to the photon energy and the exposure. Consequently, the high performance of the present measuring system has been demonstrated. (author).
