Investigations of touchscreen glasses from mobile phones for retrospective and accident dosimetry

摘要: Abstract Touchscreen glasses of mobile phones are sensitive to ionizing radiation and have the potential usage as an emergency dosimeter for retrospective dosimetry purpose triage after a radiological accident or attack. In this study TL glow curves dosimetric properties touchscreen were studied in detail, such intrinsic background dose, dose response, reproducibility, optical stability long-term signal. Preliminary results additionally presented minimize by mechanically removing surface layer glass samples. Additionally chemical element analyses samples carried out investigate difference between which show signal neither zero nor induced An irradiation trial using stored dark demonstrated successful recovery. However, when applying realistic, external light exposure scenario, underestimation was observed, even though pre-bleached prior measurement. More investigations be future solve challenge low signal, if used reliable dosimeter.
