You think it's safe by 2016 standards, in the same way we thought lead in gas, or agent orange was safe by the standards of those years.
In 50 years we'll know a lot more than we do now, and hindsight will be a magical thing.
By 2060 standards, we're downright uneducated. Think about how little we knew in the late 1960's, and the stupid stuff that was done based on "we know what we're doing"

Regarding lead poisoning, it was since forever known that lead is poisonous, the "safe level" was something that was better established in last 50 years and enforced by better policies. There's no parallel for infrared and radio waves (that is, lower frequencies and energies of photons) but there is for UV or gamma rays (that is, higher frequencies and energies of photons).
The certainty with which you make these statements is the exact same certainty that scientists 50 or 100 years ago used to justify doing all kinds of shit we now know caused unforeseen harm.
Don't focus on the one example I gave, focus on that fact that we continually mess with stuff we don't understand, with consequences we can't comprehend. Then 50 years later we just say "we know better now" and proceed to mess it all up in different ways. Repeat.
It's amazing we're not all dead yet, isn't it? messing with everything like we have, vastly extending expected lifespan and years of health...
Tens of thousands of living things that used to call this planet home are extinct thanks to our meddling. I'd say that's proof enough we're badly f'ing things up.
Probably much more:
https://en.wikipedia.org/wiki/Holocene_extinction
"the present rate of extinction may be up to 140,000 species per year,[2] making it the greatest loss of biodiversity since the Cretaceous–Paleogene extinction event."
But you will provoke people by saying things like this. I have been heavily down voted else in this thread for saying something like this
I guess it is because people have great difficulty in looking from outside their current time frame. For example, people always thing that they are living in "modern times".
We were living in modern times in the 50's, 60's, 70's, 80's, just like we are living in modern times now. People find it hard to comprehend that their times will once be old, and their beliefs and assumptions about the world obsolete, and their scientists proved wrong. It just does not occur to them.
This might be giving some kind of false belief that we know nearly all there is to know, which lead to fallacies like the parent comment. He implies we know all there is to know about the exposure to radiation.
A quote from Mark twain comes to mind.
"It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so"
Human beings should learn to be modest. How small we are, and how little we know. Then may be we will proceed with more caution and be less reckless with imposing our will upon the other living things on this planet...
We (as humanity) do "mess with the stuff" and we (as in scientists) even know exactly where and how much we (as in "political and economic forces") do that. The amount of fossil fuels use is one good example. And having huge nuclear stockpiles ready for launch is another. And we "know better" (as in knowing that the effects won't be desirable for "us") even now, but look how many forces pretend we don't.
Having basic scientific literacy actually matters, otherwise you'll fall worrying for pure distractions, like "you should worry that mobile phones emit radio waves to your brain." No, either forget it, that's pure distraction, or at least, learn a little of physics, you'll benefit from that.
And we don't have to wait 50 years. We already know the exact problems that will be much bigger in 50 years if we don't act.
Of course, I doubt that any of that went through your head. You just pointed at something that caught your attention, completely failing to consider all of the other things that are likely similarly dangerous like aluminum cans, pickled vegetables, soap, clothing, light bulbs, the English language, and so on and so forth. All of those are just as potentially dangerous as cell phones.
I think that you would be well served by studying epistemology, philosophy of science, and rational utilitarianism. I believe that you will find some ideas that will be useful to to you in the future.
