Swedish Radiation Protection Foundation Submits Major Evidence to US Health Authorities on Wireless Radiation and Public Health
The EM Radiation Research Trust wishes to draw attention to an important submission by the Swedish Radiation Protection Foundation to the US Department of Health and Human Services (HHS), responding to its Request for Information on Electromagnetic Fields (EMFs), Radiofrequency (RF) Radiation and Wireless Radiation Exposure.
The submission, presented by Mona Nilsson, Director of the Swedish Radiation Protection Foundation and a member of the Radiation Research Trust’s Advisory Committee, brings together scientific research, published studies and recommendations concerning reported health and environmental effects of exposure to wireless radiation.
Mona has worked extensively with Swedish scientist Dr Lennart Hardell on research investigating reported health effects associated with radiofrequency radiation, including exposure from mobile phone masts, 4G and 5G infrastructure.
The submission includes 19 supporting documents and raises important questions about whether current exposure standards adequately protect the public, particularly children and other potentially vulnerable groups.
Key concerns raised in the submission
1. Health concerns associated with 5G infrastructure
The submission highlights a series of published case studies by Mona Nilsson and Dr Lennart Hardell involving people living or working close to newly installed 5G base stations.
The researchers report symptoms including:
- ● Sleep disturbances and severe insomnia.
- ● Headaches and persistent fatigue.
- ● Concentration and memory difficulties.
- ● Dizziness, agitation and skin complaints.
The case studies describe individuals who reported developing symptoms following the activation of nearby 5G infrastructure, with some reporting improvement after moving to locations with lower measured exposure.
The authors argue that these observations warrant further investigation through larger, independently conducted studies.
2. Are existing exposure limits sufficiently protective?
A central concern is that current FCC and ICNIRP exposure guidelines are primarily based on thermal effects of radiofrequency radiation.
The Swedish submission highlights scientific literature reporting biological and health effects at exposure levels below existing guidelines and questions whether the current approach adequately addresses non-thermal effects and long-term, continuous exposure.
It also draws attention to the EuropaEM EMF Guideline (2016), which proposes substantially lower precautionary exposure levels.
3. Children, pregnancy and vulnerable populations
The submission calls for particular attention to children, pregnant women, older adults and people with existing health conditions.
It highlights research investigating associations between exposure during pregnancy and childhood behavioural and neurological outcomes, alongside animal studies examining effects on brain development.
The authors argue that these populations should receive greater consideration in future exposure assessments and public health protection policies.
4. Sleep, memory and cognitive health
Mona Nilsson and her collaborators draw attention to Swedish and Norwegian health statistics showing substantial increases in recorded sleep and memory-related diagnoses in certain age groups.
They suggest that increasing exposure to wireless radiation should be investigated as one possible contributing factor. The submission also raises questions about possible long-term neurological effects and the need for research into neurodegenerative diseases.
5. Smart meters, Wi-Fi and cumulative exposure
The submission highlights concerns about the growing number of wireless devices and infrastructure sources contributing to everyday RF exposure.
It calls for better assessment of cumulative exposure in homes, schools, workplaces, hospitals and residential care facilities.
It also recommends greater use of wired alternatives, including Ethernet connections, where practical, to reduce unnecessary wireless exposure.
6. Environmental and wildlife impacts
The Swedish Foundation also raises concerns about potential effects on wildlife, birds, livestock and domestic animals.
It refers to research by Professor Henry Lai and Blake Levitt concerning electromagnetic fields and wildlife, and calls for better environmental monitoring and systematic reporting of suspected adverse effects in animals.
7. Independent research and scientific transparency
An important section examines potential conflicts of interest in the development of exposure standards and the involvement of industry-funded research and experts affiliated with international advisory organisations.
The submission calls for greater transparency concerning research funding, conflicts of interest and the composition of scientific expert groups.
It argues that independent scientific assessment is essential when determining policies intended to protect public health.
Recommendations to US health authorities
Among the recommendations made by the Swedish Radiation Protection Foundation are:
- ● Reassess existing RF exposure limits in light of research concerning potential biological and non-thermal effects.
- ● Prioritise independent research into long-term exposure from 4G, 5G, Wi-Fi and emerging 6G technologies.
- ● Improve exposure monitoring in homes, schools, workplaces and other public environments.
- ● Establish better systems for recording and investigating suspected adverse health effects.
- ● Give greater consideration to children, pregnant women, older adults and potentially sensitive individuals.
- ● Investigate possible environmental and wildlife effects.
- ● Improve public and healthcare professional awareness of the issues.
- ● Promote practical measures to reduce unnecessary RF exposure.
Recognising Mona Nilsson’s contribution
Mona Nilsson is a member of the Radiation Research Trust’s Advisory Committee. Her work, alongside Dr Lennart Hardell, has contributed to the international discussion about the reported health implications of wireless technologies and the adequacy of existing exposure standards.
We welcome the Swedish Radiation Protection Foundation’s contribution to this important HHS consultation and believe the evidence and questions it raises deserve careful and urgent consideration.
The growing dependence on wireless technologies makes independent research, transparent scientific assessment and effective public health protection increasingly important.
We encourage our followers, researchers, health professionals and policymakers to read the Swedish submission in full and consider the scientific evidence and recommendations it presents.
