A small-scale realistic inter-laboratory accident dosimetry comparison using the TL/OSL from mobile phone components

RENEB Inter-Laboratory Comparison 2021: Inter-Assay Comparison of Eight Dosimetry Assays

“…For instance, using glass or resistors from mobile phones provided promising dose estimates in this exercise, but front or side irradiation of mobile phones using the same dose would result in different dose estimates. For this reason, the angle response for display glass was simulated by Monte Carlo simulations and varied experimentally in laboratory irradiations with gamma and X-ray sources ( 60, 77, 78 ). Possible irradiation geometries as depicted in Fig.…”

Reflections on the future developments of research in retrospective physical dosimetry

“…[9] was confirmed in Refs. [88,120]. However, the reasons for under-or overestimation of doses were not systematically explained.…”

“…Field tests exercises (Table 2) were also carried out (e.g., Refs. [43,88,119,120]; here, irradiations were made in more realistic conditions, with mobile phones and other materials placed on anthropomorphic phantoms. The participants were required to use the protocols used in Refs.…”

Feasibility Study of Using Earbuds and Wireless Headphones for Retrospective Dosimetry

“…A standardized measurement protocol (Bassinet et al, 2014a) was applied in this study. This protocol called "OSL with preheat" was developed using OSL of resistors extracted from the circuit board of mobile phones in the framework of the EU-FP7 MULTIBIODOSE project and tested in several interlaboratory comparisons for retrospective dosimetry and field tests in the framework of the EU-FP7 CATO project (Discher et al, 2021), the "European Radiation Dosimetry" (EURADOS) WG 10 and "Running the European Network for Biological Dosimetry and Retrospective Physical Dosimetry" (RENEB) network (Waldner et al, 2021)), the "Korea retrospective dosimetry network" (KREDOS) group (Kim et al, 2022) and, more recently, again the RENEB network (Port et al, 2023). The OSL signals were measured at 100 • C for 30 s after a preheat up to 120 • C for 10 s. The calibration dose was approx.…”
