An efficient approach to routine TL dosimetry.
A new labour-saving protocol for clinical dosimetric measurements based on the thermoluminescence (TL) of lithium fluoride is presented. The accuracy of dose measurements resulting from the application of this protocol is examined with particular emphasis on the linearity, reproducibility, and fading of TL response. It is shown that the technique described here is capable of yielding an accuracy of +/- 5% at the 95% confidence level for doses in excess of 1cGy. This study establishes that adoption of the protocol can result in significant savings in labour whilst maintaining a level of accuracy that is adequate for clinical dosimetry.
