6 shows the TSL glow curve of natural, natural plus irradiation induced curves together with annealed P6 sample.
A typical glow curve of P4 sample is shown in Figure.
The NTL and ATL glow curve characteristics were measured for all the twenty seven samples.
Typical ATL glow curve of quartz samples of all the sites were recorded at a heating rate of 10[degrees]C/s after irradiating with a gamma dose of 3.
This difference is conveniently measured at 300 [degrees] C, as the TL at that temperature is stable and the 325 [degrees] C peak represents approximately half the TL intensity in the unbleached glow curve of these samples, and therefore the fraction of the pooled mean age dose contributed by the regrown 325 [degrees] C peak approximates half the proportion of the true age to the published age of this sample.
1996): figure 21, which shows TL glow curves measured for sample number W1647 from excavation trench TL9 (in the rock-shelter) and for sample number W1752 from the sandsheet auger hole 5 TL14.
The glow curve patterns of natural, gamma exposed (raw and annealed) samples are discussed.
The natural glow curves are always of the same shape, showing a low variation in intensity.
The duration time of 1000 h or 2000 h has no further influence on the shape of the glow curve
A glow curve
reader was assembled using a fabricated microcontroller-based temperature programmer, SES regulated power supply (1050 volt.
Following X-irradiation and subsequent heating in the temperature interval 23-200[degrees]C, TL glow curves
produced characteristic emissions near 75[degrees]C and 100[degrees]C from the crystalline and amorphous regions, respectively.
The glow curves
of thermoluminophors were measured by a thermoluminescence reader (TLD reader) UPF-02 (Moscow, Russia).
