On the dose rate dependence of radiofluorescence signals of natural quartz

The general behaviour of the main UV emission during radiofluorescence (RF) in natural quartz with dose rates ranging from 10 to 500 mGy s−1 is analysed. RF emission spectra were recorded and deconvolved to extract information on the C band, which is often the main emission of quartz annealed at a t...

Zusammenfassung:The general behaviour of the main UV emission during radiofluorescence (RF) in natural quartz with dose rates ranging from 10 to 500 mGy s−1 is analysed. RF emission spectra were recorded and deconvolved to extract information on the C band, which is often the main emission of quartz annealed at a temperature close to 500 °C. Our results confirmed theoretical findings, e.g., the direct proportionality of the initial RF signal of the C band with dose rate and the direct proportionality of the initial slope with the squared dose rate. Furthermore, numerical simulations employing a three-energy-level model and experimental data are in agreement. A first concept of using quartz UV-RF for dosimetric application is given based on the findings that different absorbed doses resulting from different dose rates match well into a single UV-RF decay curve.
