My comments are on an individual basis. I am a retired civil engineer and occupational and design safety advisor based in South Wales, UK. 

Question 3: I often feel slightly dizzy when in built-up areas. I also used to regularly feel both dizzy and slightly nauseous whilst at home. However, after I disabled Wi-fi at home – replaced with wired connections - and, more recently, changed my DECT telephone for a wired landline, my symptoms went. They did, however, return on one occasion but on investigation, I discovered that our DECT telephone had inadvertently been switched back on; after disabling it, my symptoms went again.

Approximately 15 years ago, I raised health concerns regarding possible adverse health effects due to long-term exposure to EMF radiation when the office I worked in was fitted with multiple Wi-fi boasters. The advice I was given at that time was that it was safe. However, this reassurance did not quieten my concerns and I began to work from home more often in order to reduce my exposure. It is noted, with extreme concern, that in the last two years, an unusually high number of staff within the same office - all reasonable young and reasonable fit - have suffered from various cancers.

Question 5: It is understood that the USA/FCC wireless radiation limit is some 25 times greater than that adopted in China and a hundred times greater than that adopted in Russia. In order to hopefully partly address this significant discrepancy, it is noted that a lawsuit was filed against the Federal Republic of Germany, as recent as 29 September 2026, demanding that the limits for mobile phone radiation, which have remained unchanged since their introduction in 1996, be reassessed and significantly tightened.

Question 6: Over the last eight years, I have sent overwhelming evidence of harm from numerous peer-reviewed studies to numerous parties – including my local Council and planning authority, Members of the Senedd (Welsh Parliament), Ministers in the Welsh Government, Public Health Wales, UK Members of Parliament, the UK Health Security Agency, the media, and many others. But all of my concerns and evidence of harm have either been ignored or a stock response provided - ‘that there is no convincing evidence that RF field exposure below guideline levels causes health effects in adults or children’. 
And this is despite c. 90% of peer-reviewed studies over the last 30-years finding ‘significant adverse effects’ [Electromagnetic Radiation Safety: Effects of Exposure to Electromagnetic Fields: Thirty years of research]. And despite the fact that the ICNIRP, WHO, SCENIHR and SSM have been criticised for dismissing studies that show evidence of harm [Buchner K, Rivasi M: The International Commission on Non-Ionizing Radiation Protection: Conflicts of interest, corporate capture and the push for 5G, 2020]. And even despite the fact that the latest WHO systematic review on animal carcinogenicity concluded that ‘there is high certainty of the evidence linking cell phone radiofrequency (RF) radiation to two types of cancer in animals; and that both these tumour types had previously been found in studies on humans.’

No doubt you will already be fully aware of all of the more recent peer-reviewed studies, but I would like to record two of note. An American study, 12 March 2026, that found that ‘One in 8 U.S. adults reported adverse health effects from exposure to wireless radiation’ [1 in 8 U.S. Adults Say Wireless Radiation Is Causing Health Issues — What Does That Mean for Kids’ Health? • Children's Health Defense]. And an Australian study, 17th March 2026, that found that ‘overall, 18.9% of Australians reported having wireless sensitivity, diagnosed EHS, or both conditions' .[final_wireless_sensitivity_prevalence_media_release_17_mar_26.pdf].

Question 8: Until how implant and other proximity-related risks are to be assessed consistently in spatial terms is resolved, placing sole reliance on a Certificate of Conformity is not a sufficiently robust basis for identifying and assessing proximity-related risks as part of an Authority’s obligations to reconcile public health and environmental implications.
