evidence: Concerns about the impact of 5G on human health are largely centred around radiofrequency electromagnetic fields (RF-EMF), the part of the spectrum with frequencies between about 20 KHz to 300 GHz. With 5G set to revolutionise everything from communication to industry, understanding its implications is critical. This is where the GOLIAT project, a pioneering research initiative under the Horizon Europe programme, steps in. [...] 5G makes use of non-ionising radiation, specifically RF-EMF below 6 GHz, which is used in everything from mobile phones to Wi-Fi routers. Unlike ionising radiation, RF-EMF does not have enough energy to break chemical bonds in molecules, but its increasingly widespread use raises important questions about the potential effects related to long-term exposure. Particularly vulnerable populations may include young people and workers in industries where 5G is deployed. [...] In a controlled cross-over quasi-experimental design, the University of Bristol will recruit companies where 5G technology is being used. They aim to conduct repeated measurements of both exposure and neuropsychological outcomes before and after 5G implementation, with a control group for comparison. This method will allow researchers to draw robust conclusions about the potential health risks posed by 5G in occupational settings.
