RF-EMF brain dose from mobile phones and the role of reception quality - a simulation study using the ETAIN 5G Scientist App.

Suboptimal network signal quality can increase mobile phone-related brain RF-EMF dose by up to 37 times compared to optimal conditions.

• Why it matters: Understanding how signal quality influences RF-EMF exposure is crucial for accurate risk assessment and health guidelines, especially as 5G networks expand.
• What they did: Using the ETAIN 5G-Scientist app, researchers collected signal strength data from 4G and 5G networks in the Netherlands (2024-2025) and estimated brain doses during typical phone activities.
• The result: Findings show that poor signal quality significantly elevates brain dose levels during brief calls, highlighting the importance of considering network conditions in exposure and epidemiological studies.
