Thank you itcrowd for your thoughtful reply and for going deeper into this. I think you have spelled out our common ground in points 1-3 very well. And thank you also for digging up these other articles. I had a look at [5].

So our difference seems to be, as you mentioned, whether we believe 5G deployment (sorry, I avoid the term "rollout" since I cannot stomach this term any more, it is used so repeatedly and reflexively in practically every article dealing with the subject :) ) should be halted or slowed before more research has been done as to its health effects. I see this as a question of ethics. The technology, of course, is being rushed to deployment and by its nature will will reach everyone within range of its multitude of base stations. The people within their range will have no say as to whether or not they will be immersed in this radiofrequency radiation. At our current state of knowledge, we do not know whether the new 5G technology poses a significant threat of harm to humans, or a moderate threat, or a small threat, or no threat at all. The previous, related technology (3G, 4G, wi-fi, cell phones themselves, etc.) has been shown by the majority of the (independent) literature to pose health risks that are very much worthy of concern. The 5G technology involves a much greater number of base stations at close proximity to each other and humans, as well as a different, higher frequency whose effects on humans are unknown since apparently untested. Looking at this situation as a whole from the point of view of ethics, I think that it is very reasonable to assume that the new 5G technology could have significant health effects and that immersing the population in the radiofrequency radiation from this technology without first ruling out these plausible health effects, in the interest of not impeding the progress of the technology, is seriously problematic.

"The precautionary principle" is often cited in this connection, and I have to wholeheartedly agree with it.

Another aspect to take into account is that if the technology is studied thoroughly beforehand as to its possible health effects, it may be possible to amend the technology if necessary, or formulate precautionary measures, to minimize the health impact while still introducing the technology.

Deploying the technology before thorough testing amounts, I believe, to a crapshoot, "flying blind" as the U.S. Senator Blumenthal said in a congressional hearing in which he questioned senior members of the wireless industry. The technology is being pushed forward (for which the wireless industry and the government certainly have their own interests which do not overlap with those of the public, though one could argue that the higher download speeds (which I consider to be pretty trivial in the big picture) and other, future as-of-yet ill-defined applications of 5G (internet of things, etc.) could be of benefit to the public), and effectively we are just going to wait and watch and see if it hurts people a lot, a little, or not at all. I do not see how this can be considered in the least responsible.

I would be interested to know your thoughts and reflections on this ethical question, and of any other members of this forum who would like to chime in.
