The overarching aim of GOLIAT is to characterize and monitor RF-EMF exposure, in particular 5G, provide novel insights into potential causal neuropsychological and biological effects, and understand risk perception and communication through citizen engagement using an integrative and transdisciplinary pan-European approach. GOLIAT will ensure that the objectives are measurable, verifiable, achievable, and highly relevant for policy through: focusing on the most vulnerable (i.e. young people) and most exposed (i.e. workers) populations; implementing novel and robust methodologies including next-generation exposure assessment, causal inference, experimental work, health impact assessment, mental models, and ethical values assessment; placing a strong emphasis on translation of knowledge and citizen engagement; and developing a FAIR data infrastructure for use during and beyond the project.
