The thermoluminescence properties of novel thin (100 μm) dosemeters of clear fused quartz (CFQ) have been investigated as part of a progranime to optimise the measurement of the spatial beta dose distribution around hot particles and to provide benchmark measurements for the parallel validation of Monte Carlo code calculations. Using the isothermal annealing method seven TL peaks (P1-P7) have been identified for CFQ in the temperature range 122-310°C. The isothermal method has been used to determine the energy depth E and frequency factor s for peaks P2, P3 and P4. The heating rates method has been used to determine the values of E and s for peaks P1 and P6. The results have been compared with'those of computerised glow curve deconvolution. There were large disparities between the results of different methods. These are probably due to artefacts in the methods related to the large number of overlapping peaks. The reproducibility of individual CFQ on the basis of TL integration up to 400°C is good (±5%). On the other hand, the individual sensitivity is different among all the dosemeters (40) from the same batch and the difference in the TL signals sometimes reaches a factor of 5. An analysis of the TL dose response in terms of low and high temperature regions (PL, 50-150°C; P H , 250-350°C) showed a linear response up to ∼60 Gy for PL and a slightly sub-linear response up to only -2 Gy for PH. The sensitivity of CFQ has been found to be -15% of that of LiF TLD 100 and the minimum detectable dose (2σ above background) is ∼580 μGy. The TL response of CFQ was found to be sensitive to natural light exposure. The TL yield was reduced to typically 20% of is original value after only 10 h exposure to natural light at room temperature. After this period of time both peak P1 and peak P2 have been completely removed. Samples kept shielded from light suffered only a 12% decrease of total TL intensity after 48 h at room temperature, A feasibility study has been carried out successfully using CFQ to measure directly the dose distribution around a test 60 Co hot particle source using an imaging photon detector (IPD) technique. CFQ/IPD measurements have a much greater sensitivity than extrapolation chamber and radiochromic dye film techniques, which have previously been used for this application.
