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 (LaBr3(Ce), SrI2(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 Se-75, I-131, Ir-192 and Co-60 in some locations of the Radiological Surveillance Network of Catalonia (Spain).
