Okay, I worded it poorly. I was irritated that the issue of<br>
safety was diverted into a narrow discussion of brain cancer, as<br>
if that was the only issue to consider.<br>
<br>
Doug's message (the above link) only mentioned brain cancer as an<br>
example, but his message was essentially about broader health<br>
concerns, which included what I thought was good commentary on<br>
the interaction of several factors on biological injury. You<br>
can't look at just one of them.<br></blockquote><div><br></div><div style="font-size:small" class="gmail_default">What are the broader health concerns of RF and what is the evidence <br></div><div style="font-size:small" class="gmail_default">for them?</div><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default">Here is what Health Canada says about WiFi (which is what started the thread):</div><div style="font-size:small" class="gmail_default"><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="font-size:small" class="gmail_default">Based on the current scientific evidence the level of radiofrequency EMF emitted from Wi-Fi devices <strong>is not</strong> harmful to health.</div></blockquote><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default">Note the sources they cite:</div><div style="font-size:small" class="gmail_default"><ul><li>World Health Organization</li><li>U.K. Health Security Agency</li><li>Institute of Electrical and Electronics Engineers</li><li>International Commission on Non-Ionizing Radiation Protection</li></ul></div><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default"><a href="https://www.canada.ca/en/health-canada/services/health-risks-safety/radiation/everyday-things-emit-radiation/wi-fi.html">https://www.canada.ca/en/health-canada/services/health-risks-safety/radiation/everyday-things-emit-radiation/wi-fi.html</a></div><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default">Here is another study that is wider (mobile phones as well as WiFi).<br></div></div><div class="gmail_quote"><br></div><div class="gmail_quote"><div style="font-size:small" class="gmail_default"><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9287836/">https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9287836/</a></div></div><div class="gmail_quote"><br></div><div class="gmail_quote"><div style="font-size:small" class="gmail_default">The conclusion:</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="font-size:small" class="gmail_default">The only evidence-based biological effects of
exposure to RF EMF in the frequency range of 300 kHz – 300 GHz – which
includes mobile phones, mobile phone base stations, and Wi-Fi networks –
are thermal effects. However, the health risks associated with
temperature rise are virtually null with normal Wi-Fi use, and even with
the use of a mobile phone next to the head.</div><div style="font-size:small" class="gmail_default"><p>As for non-thermal
effects, scientific evidence is insufficient and inconsistent. Present
data do not provide clear evidence of adverse effects in humans. Further
research based on much more precise dosimetry procedures and protocols
supported by simulations of RF field distribution inside the biological
tissue is needed.</p><p class="gmail-p gmail-p-last">To conclude, human exposure to
Wi-Fi RF fields, including exposure of children in schools, is very low
and, in most cases lower than to other EMF sources in the environment.
With this in mind, we, children and adults alike, should be following
the practical advice to monitor and limit the use of Wi-Fi and mobile
technology, as RF fields have become an unavoidable environment in and
with which we have to live. There are almost no places on the Earth not
covered with some of the RF fields. We have to monitor the ones which
are man-made and research their possible impact on human and non-human
genetic and physiological structure.</p></div></blockquote><div style="font-size:small" class="gmail_default">If there is evidence to the contrary, where is it, and was it scrutinized by subject matter experts?<br></div><br></div></div>
