Visualizing radiofrequency electromagnetic field exposure through Voronoi-based maps
This exposure-assessment study proposes a Voronoi-diagram approach to visualize RF-EMF exposure across a city using personal exposimeter measurements of RMS electric field at seed points. Most mapped areas corresponded to about 1.9 V/m, with a maximum reported value of 11.4 V/m, all below the cited ICNIRP guideline level. The authors conclude the method is useful for communicating spatial variability, while also noting broader literature discussing potential health risks from EMF exposure.
Key points
- The city was partitioned into Voronoi cells based on Euclidean distance to measurement seed points.
- RMS electric field was measured with a personal exposimeter at each seed point and assigned to the corresponding cell.
- Maps were generated with varying numbers of cells (5 to 100), with higher counts yielding smaller cells and more stable mapping.
- Most areas were mapped as approximately 1.9 V/m at seed points, compared with an ICNIRP guideline maximum of 61.4 V/m.
- Three cells exceeded 3.9 V/m and the maximum measured value reported was 11.4 V/m.
- Cell color changes reflected updated measurements and highlighted spatial variability across the city.
- The authors frame the method as supporting community exposure assessment and public health communication, while acknowledging literature linking EMF exposure to potential health risks.
