Abstract In the framework of the European Project CONFIDENCE („COping with uNcertainties For Improved modelling and DEcision making in Nuclear emergenCiEs“), the characterization of two applications (“RadioactivityCounter and “GammaPix”) that enable dose-rate measurements with an ordinary smartphone was carried out. In case of a nuclear emergency, such softwares allow to use the CMOS sensor of the built-in camera as a radiation detector. This paper presents the results of the scientific investigation on the reliability of the so-called “citizen measurements” performed with 14 different mobile phones chosen among the most common brands sold in 2017. All tests were carried out at room temperature and in different reference fields at the Secondary Standard Dosimetry Laboratory of the Helmholtz Zentrum Munchen. Investigated properties were the response at different dose-rate levels, influence of integration time, background, energy dependence and angular dependence.

基于智能手机 CMOS 传感器的外部剂量率测量

摘要 在欧洲项目信心（“应对不确定性以改进核应急中的建模和决策制定”）的框架内，对使用普通智能手机进行剂量率测量的两个应用程序（“RadioactivityCounter 和“GammaPix”）的表征是执行。在发生核紧急情况时，此类软件允许使用内置摄像头的 CMOS 传感器作为辐射探测器。本文介绍了对 2017 年销售的最常见品牌中选出的 14 款不同手机进行的所谓“公民测量”可靠性的科学调查结果。所有测试均在室温和不同参考领域进行在慕尼黑亥姆霍兹中心的二级标准剂量学实验室。
