Project GOLIAT is studying exposure to radio frequency electromagnetic fields (RF-EMF), particularly 5G, and its potential health effects, as well as risk perception through citizen participation.
Exposure to radiofrequency electromagnetic fields is measured in various indoor and outdoor microenvironments. In the context of this study, a microenvironment can be a residential area, a city centre, a shopping area, a school, a train station or a public transport route.
To carry out the measurements, several study areas have been selected according to population density: a large city (such as Barcelona), a smaller city (between 100 and 500,000 inhabitants, such as Mataró, in the case of Spain) and three villages or rural areas.
State-of-the-art exposure equipment is needed to experimentally assess the biological effects associated with 5G exposure. The project team uses a personal exposure meter (ExpoM-RF 4) and a mobile device equipped with an additional RF-EMF sensor.
Using a mobile application, the team marks the type of scenario in which exposure to radiofrequency electromagnetic fields is measured.
One of the populations studied in the GOLIAT project is young people. Today, children, adolescents and young adults are more exposed to radio frequency electromagnetic fields from new generation wireless networks, such as 5G. This heightened exposure raises concerns about their vulnerability to potential health effects.
GOLIAT will measure exposure in ten European and two Asian countries. At least 176 measurements per country are to be carried out in up to 84 microenvironments. This number is likely to be higher depending on the number of public transport journeys between the micro-environments and between the selected cities or towns.
The measuring equipment is placed in a backpack. Once active, the research technician carries the backpack and walks around the city to take measurements. The equipment used, which is geolocated, takes a reading every few seconds. Each stage takes about 15 minutes.
The recorded data enables the comparison of the different measurements and helps identify the points where peaks of RF-EMF exposure have been recorded.
As part of the project, two exposure measurement campaigns are planned. The same process will be repeated in the 12 countries participating in the GOLIAT project: Spain, Switzerland, Belgium, France, Italy, Poland, Hungary, Netherlands, Austria, United Kingdom, Japan and Korea.
