“…It should be noted that most of 4 the recent published works are focused on the TL and/or OSL study of glass materials commonly found in daily life (window glass, bottle glass, watch glass, glass display from mobile phones) in search of new dosimetric materials for accidental or retrospective dosimetry (e.g. Engin et al, 2010;Moffatt et al, 2012;Teixeira et al, 2008;Discher et al, 2013). However, the present work, for the first time to the authors' best knowledge, aims to explore the adequacy of glass containers for drugs as probes for the post-sterilization dosimetry on commercial liquid drugs.…”

“…The absorbed dose measurement is influenced in this case by the presence of an intrinsic background signal and signal fading 103 . The intrinsic background signal can be reduced by etching the glass sample in concentrated HF before measurement but not completely eliminated 104 . In both cases (etched or unetched), the distribution of intrinsic background doses could be shown to approximately follow a log-normal distribution.…”

Biological and physical retrospective dosimetry are recognised as key techniques to provide individual estimates of dose following unplanned exposures to ionising radiation. Whilst there has been a relatively large amount of recent development in the biological and physical procedures, development of statistical analysis techniques has failed to keep pace. The aim of this paper is to review the current state of the art in uncertainty analysis techniques across the 'EURADOS Working Group 10-Retrospective dosimetry' members, to give concrete examples of implementation of the techniques recommended in the international standards, and to further promote the use of Monte Carlo techniques to support characterisation of uncertainties. It is concluded that sufficient techniques are available and in use by most laboratories for acute, whole body exposures to highly penetrating radiation, but further work will be required to ensure that statistical analysis is always wholly sufficient for the more complex exposure scenarios.

“…It came mainly from the glass surface layers. Methods had been proposed to reduce it using a mechanical treatment ( 11 ) by grinding the glass surface or a chemical treatment ( 12 ) by etching the glass with hydrofluoric acid (HF 40%). The screen protector glasses are too thin to use a mechanical treatment to try to reduce the contribution of the intrinsic background signal.…”

Screen protector glasses are often used to protect the display screen surface of mobile phones against physical damage. Their dosimetric properties were recently studied by thermoluminescence with the aim of using these items as potential emergency dosimeters in the event of a radiological accident. They are sensitive to ionizing radiation and they could be easily removed and replaced without destroying the phone in case of a dose assessment. However, an intrinsic background signal that partially overlaps with the radiation-induced TL signal is observed. The reconstructed dose could be overestimated if not properly taken into account. The homogeneity of this confounding signal on the surface of several screen protectors was estimated and a chemical treatment with hydrofluoric acid (HF 40%) was tested to minimize its contribution. For most of the samples studied, the intrinsic background signal remained a serious issue for dose reconstruction. Additionally, the TL signals were measured in the red detector range using two different models of red-sensitive photomultiplier tubes. The homogeneity of the intrinsic background signal on the surface of screen protectors was examined and the results of the reduction of this signal by the chemical HF treatment were discussed.
