Comprehensive remote calibration of detectors in a radiological surveillance network: From basic response to high-level data analysis

Year: 2024

Type: article

Abstract: We present a new procedure to remotely calibrate gamma spectrometry detectors installed in the open air used in surveillance networks. The procedure includes energy calibration, determination of the energy resolution and estimation of the activity concentration. Our Proportional ROI-Cleaning algorithm (Cerezo et al., 2023) has been applied to different detector types and dimensions (LaBr 3 (Ce), SrI 2 (Eu) and NaI(Tl)). These detectors are assembled in different measuring configurations (direct and with particulate filter). The usefulness of our method as a surveillance technique was confirmed by the detection of 75 Se, 131 I, 192 Ir and 60 Co in some locations of the Radiological Surveillance Network of Catalonia (Spain).
