An advanced ionizing radiation monitoring network (AIRMN) system using a single-crystal SrI2(Eu) scintillator has been developed. The SrI2(Eu)-scintillator (25 mmφ × 25 mm) has excellent material properties, including a high light yield (>80 000 photons/MeV), a high photoelectric cross section, and high energy resolution (<4%). The system has a multi-pixel photon counter as a light detector. The resolution and sensitivity of the new AIRMN allow the radioactive Cs originating from the Fukushima Daiichi Nuclear Power Plant accident to be distinguished from other radioactive species, leading to the precise assessment of the ambient dose originating from 134Cs and 137Cs radiation. Furthermore, a software platform is described that is adopted in the AIRMN and based on the use of the ANSI N42-42 Data File Format published by the National Institute of Standards and Technology. It allows for the standardization of ionizing radiation monitoring. Copyright © 2016 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
