5G and Health:
Separating Fact from Fiction
Is 5G dangerous? Between alarmist narratives and official downplaying, what does science really say? A factual and balanced guide to understanding the truth — with relevant sources.
5G is everywhere in public debate — between technological promises and health concerns, it's hard to make sense of it all. This article gives you the keys to understanding what science actually says, without alarmism or downplaying.
- What 5G really is and how it differs from previous generations
- The most common misconceptions — and what science truly says
- Key studies on the biological effects of radiofrequencies
- French and European legal standards (SAR, exposure limits)
- 8 concrete steps to reduce your exposure without giving up technology
Section 1 What is 5G? [Accessible Science]
5G is the fifth generation of mobile networks. It succeeds 4G/LTE and promises much higher data speeds, reduced latency, and the ability to simultaneously connect a much larger number of devices.
📡 Frequencies Used by 5G
| Band | Frequencies | Range | Throughput | In France |
|---|---|---|---|---|
| Low (Sub-1 GHz) | 700 MHz | Very long (km) | Moderate | ✅ Deployed |
| Mid (Sub-6 GHz) | 3.5 GHz | Medium (hundreds of m) | High | ✅ Primary |
| High (mmWave) | 26–28 GHz | Very short (<100 m) | Very high | ⚠️ Limited |
5G in France primarily uses the 3.5 GHz band — a frequency similar to the 5 GHz WiFi you probably already use at home. The very high frequency mmWave band is almost absent from current French deployment.
Section 2 The Great Untangling: True or False? [Common Misconceptions]
5G waves are non-ionizing radiation — they do not have enough energy to break the chemical bonds of DNA molecules. Only ionizing radiation (UV, X-rays, gamma rays) has this capability. This is a fundamental confusion in many alarmist narratives.
The transmit power of 5G antennas is regulated and comparable to that of 4G antennas. What changes is efficiency: 5G transmits more data with similar power, thanks to directional beamforming techniques. Exposure levels measured in the field remain well below legal thresholds.
This is accurate and acknowledged by ANSES itself in its 2021 report. Further research is explicitly requested on the long-term effects of 5G specifically. The absence of proof of danger is not proof of the absence of danger — this is the logic of the precautionary principle.
ICNIRP limits are established based on short-term thermal effects (heat). Independent researchers (BioInitiative, Prof. Salford) highlight that non-thermal biological effects have been documented at levels well below legal limits. The scientific debate is real.
Section 3 Health Effects: What Science Says [Analysis]
The International Agency for Research on Cancer (IARC/WHO) has classified radiofrequency electromagnetic fields as Group 2B: "Possibly carcinogenic" since 2011 — a classification maintained to this day, which also applies to 5G.
| Study / Organization | Conclusion | Level of Evidence |
|---|---|---|
| ANSES 2021 | Biological effects documented at low exposure, call for precaution | 🟠 Moderate |
| NTP Program (USA, 2018) | Association between RF and heart tumors in male rats | 🟠 Moderate |
| Interphone Study (WHO, 2010) | Intense use >10 years: increased risk of ipsilateral glioma | 🟡 Limited |
| BioInitiative 2012/2014 | Synthesis of 1,800+ studies: non-thermal effects documented | 🟠 Moderate |
| ICNIRP 2020 | No evidence of health effects at actual exposure levels | 🟢 Official |
ANSES (the official French health safety agency) explicitly recommends applying the precautionary principle and limiting exposure to radiofrequencies, especially for children and electro-sensitive individuals. This recommendation applies to all network generations, including 5G.
Section 4 Your Daily Exposure: Mapping the Sources
| Source | Frequency | Typical Distance | Exposure Level |
|---|---|---|---|
| 5G Relay Antenna | 700 MHz – 3.5 GHz | 50–500 m | 🟡 Low (distance) |
| 5G Smartphone (call) | 700 MHz – 3.5 GHz | 0 cm (ear) | 🔴 High (SAR) |
| 5 GHz WiFi Box | 5 GHz | 1–5 m | 🟠 Medium |
| Tablet / WiFi Laptop | 2.4 – 5 GHz | 20–50 cm | 🟠 Medium |
| Smartwatch | 2.4 GHz BT | 0 cm (wrist) | 🟠 Medium-continuous |
| Connected TV (standby) | 2.4 GHz | 2–4 m | 🟡 Low |
SAR (Specific Absorption Rate) measures the amount of electromagnetic energy absorbed by the body. The legal limit in France is 2 W/kg (head/trunk) and 4 W/kg (limbs). The Phonegate scandal revealed that many smartphones exceed these limits during real-world tests — see our dedicated article.
Section 5 Standards and Regulations [Legal Framework]
| Text | Date | Content |
|---|---|---|
| Abeille Law | 2015 | Principle of wave sobriety — WiFi off if unused in nurseries and primary schools |
| ICNIRP Directive | 1998 / 2020 | RF exposure limits adopted by the EU and France |
| Transparency Decree | 2013 | Obligation to publish antenna exposure levels |
| Resolution 1815 CE | 2011 | Council of Europe: recommends strengthened precautionary principle |
| ANSES 5G Report | 2021 | Specific recommendations for 5G, call for additional studies |
Section 6 How to Protect Yourself Concretely [8 Actions]
📱 Systematic wired hands-free kit
The simplest and most effective action.
- Wired hands-free kit (not Bluetooth) for all calls
- Reduces brain exposure by 90 to 99% during calls
- Avoid holding the smartphone to the ear — especially in areas with poor network coverage (maximum emission)
🌙 Airplane mode at night
Your bedroom = your sanctuary.
- Airplane mode on all devices in the bedroom
- Turn off WiFi using a timed outlet (~€15)
- 8 hours without exposure = 33% reduction in total daily exposure
🔌 Favor wired connections
Each cable means one less wave.
- Ethernet cable for desktop and laptop computers
- Disable computer WiFi when connected via Ethernet
- Wired mouse and keyboard instead of Bluetooth
📏 Respect distances
Exposure decreases with the square of the distance.
- Tablet/computer: always placed on a table, never on your lap
- Smartphone: never in your pants pocket
- WiFi router: at least 2 meters from work and rest areas
Section 7 Should We Be Afraid of 5G? [Balanced Conclusion]
- 5G is not proven risk-free — but it is also not proven dangerous at current exposure levels
- The precautionary principle is a wise and scientifically justified approach
- Exposure reduction measures are simple, free, and good for your overall health
- Our patented devices, tested by NEXIO, provide measured complementary protection
