Standard TLD materials, such as LiF, LiBO, CaF and CaSO will begin 
the annealing process between 100 and 150 degrees Celsius. Complete 
readout of the glow peaks occurs at about 300 degrees Celsius, most 
often. Depending on what you're trying to measure (radiation type), 
how you calibrate and whether or not the low energy traps are an 
integral part of the measurement, the TLD "may" be viable. I expect 
that the TLD is not the optimum dosemeter for your use. Film is 
entirely out of the question due to heat sensitivity.
