Abstract

This study addresses the need for advanced nuclear waste management strategies, particularly the efficient handling of low-level radioactive waste. Traditional radiation measurement methods pose risks due to the necessity of close proximity to radioactive samples and/or high exposure times. A Compton scattering-based system as an alternative to traditional methods is proposed. The camera employs a 5mm thick CdTe sensor paired with a 55μm Timepix3 detector. The Timepix3's data-driven output allows high photon flux analysis, recording energy and time-of-arrival, vital for accurate source localization and spectrum reconstruction. The comprehensive characterization of this setup, including energy calibration, spatial resolution, and performance in radiation source detection and localization, is presented, alongside challenges and solutions during development. This innovation promises to enhance low-level radioactive waste management safety and efficiency by reducing measurement and personnel exposure time, marking a significant advancement for the nuclear industry and related fields.
