A group of researchers from the Institute of Corpuscular Physics (IFIC), a joint center of the University of Valencia and the Spanish National Research Council (CSIC), has patented a compact and portable device capable of simultaneously monitoring gamma radiation and neutrons produced in radioactive processes and nuclear reactions. This detector also makes it possible to measure these radiations with a wide range of energy and visualize them spatially, which can give rise to multiple applications: from the detection of radioactive materials in nuclear safety programs to mitigating the side effects of hadron therapy, a novel way to treat cancer.
