## Question

Does 5G expose people to more radiation than 4G?

## Answer

5G uses the same kind of non-ionizing radiofrequency energy as 4G and remains subject to the same exposure limits, so the change is in deployment pattern rather than in kind: more, lower-power nodes closer to users, plus beamforming that points energy at active devices instead of radiating uniformly. Higher mmWave bands penetrate walls and skin far less than the mid-band frequencies that carry most 5G traffic. Measurement surveys of deployed 5G to date report levels well below regulatory limits, though the research record on beamformed mmWave exposure is thinner than for earlier generations, which is a genuine gap rather than a finding of harm.

- [5G small cell / street-level node](https://emfbase.com/emitters/5g-small-cell): Pole-mounted nodes radiate roughly 10 W EIRP at street level, putting a residence 10 m away at about 8,000 µW/m² on the main beam — far below regulatory limits but often above precautionary building-biology bands.
- [Beamforming](https://emfbase.com/glossary/beamforming): 5G massive-MIMO antennas steer energy toward active users rather than radiating uniformly, so exposure is intermittent and direction-dependent.
- [WHO-commissioned systematic review of RF exposure and cancer in humans (2024)](https://emfbase.com/studies/who-rf-cancer-review-2024): A systematic review and meta-analysis of human observational studies found no association between mobile phone use and brain or head-and-neck cancers, including for long-term and heavy use.
