External dose-rate measurements based on smartphone CMOS sensors.
Radiat. Meas. 137:106403 (2020)
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.
