GammaPix TM is a software program that claims to be able to use smartphone cameras to detect ionizing radiation. NNSA’s Office of Nuclear Smuggling Detection and Deterrence (NSDD) with Brookhaven National Laboratory (BNL) are evaluating the performance of the software in detecting radioactive materials. For this purpose, a series of tests are being conducted at the Rdiation Calibration Facility Annex at BNL. The experiments include dose measurements with three types of NIST-traceable calibration sources, 60 Co, 241 Am, and 137 Cs. The recorded results by GammaPix TM are compared with the values measured by calibrated dosimeters to determine the detection thresholds. Several selected models of iPhones and Android phones with different pixel sizes and resolutions are tested. In this paper, we will present the test procedures and discuss the test results and potential applications.
