Luckily we have the ozone to filter most of the harm out.

UV at the shorter wavelength range (UV-B and C ~100-315) IS ionizing radiation. Remember, ionizing radiation simply means the radiation is carried by a wave with enough energy to pop electrons off an atom.Again there's a lot of bad arguments in support of the right conclusion. I'm not terribly worried about this. The FCC limits are conservative to begin with. That said, the short-cut reasons people keep using aren't the reasons we don't need to be worried.
Not this again...
UVA and UVB are non-ionizing and yet cause tissue damage and cancer. This idea that non-ionizing (the radiation itself isn't ionized or not, it's about the impact it has on the atoms it encounters) is automatically safe is just wrong.
RF is not harmless. Low levels of RF are probably harmless. There is a reason this is tested, and it can cause significant damage to critical tissues.
EMF doesn't mean what you think it does:
https://en.wikipedia.org/wiki/Electromotive_force
They did freak out. Not much came of it. Most people who understood radio avoided holding those things close to their heads, but by the time cell phones became common pocket devices the power levels had come down.
I suppose if you have a lot of cesium in your cells, then UVB might cause you some problems, but for biological purposes ionizing generally means 10eV or higher (~120nm or less) and that is firmly at the high end of UVC. Very little if any UVC reaches the earths surface. Sunburn and skin cancer are caused by non-ionizing UVB.UV at the shorter wavelength range (UV-B and C ~100-315) IS ionizing radiation. Remember, ionizing radiation simply means the radiation is carried by a wave with enough energy to pop electrons off an atom.
EMF can mean a bunch of things. In this case I think it was shorthand for “electromagentic field”.
RF (radio frequencies) are made of frequencies that at any sensible amplitude (power) can not possibly carry enough energy to be ionizing. They are in all sense, “harmless”.
Even the authors had to say results are “equivocal”. In fact, the control group had a lower survival rate than ANY of the experimental groups. It is still baffling why the title of the article was not supported by the results. Their conclusion was uncertain.Lol at all the uninformed posters declaring unequivocally that radiation from cellphones can’t be harmful. The reality is we have mixed evidence from animal studies. Male rats had statistically significant increases in cancer due to equivalent radiation. The results in female rats and mice were equivocal.

This was a well designed and long awaited study and the results are pretty interesting. I wouldn’t stop using a cellphone as a result, it’s way too early for that. But I would keep an eye on future studies, and I would expect companies like Samsung and Apple to, at a bare minimum, remain within current federal guidelines.
UV-B is considered ionizing. UV-A is not. RF cannot carry enough energy to split nucleotide bonds. Unless we are talking colossally-massively-outrageously high amplitude RF, that is just how it is.I suppose if you have a lot of cesium in cells, then UVB might cause you some problems, but for biological purposes ionizing generally means 10eV or higher (~120nm or less) and that is firmly at the high end of UVC.

If EMF means electromagnetic fields then the statement I commented on was still nonsensical. Xrays also form electromagnetic fields. It doesn't matter what end of the spectrum you're talking about...
RF is not in all senses harmless-- that's the whole point of SAR and MPE testing. Get this ionizing/non-ionizing nonsense out of your head. It's an overly simplistic view of the world. Yes, ionizing is bad, but it's not the only bad.
And because people can't seem to understand nuanced arguments, I'll repeat that I'm in no way saying that your iPhone is giving you cancer.
I don't see it mentioned that this is a class action lawsuitI approve of this lawsuit. I’m onboard and I can’t wait to get paid.
UVB is considered ionizing by who in what context? The FCC considers photons over 10eV to be ionizing from a biological perspective. The WHO says 12.4eV. Both are firmly in the UVC range.UV-B is considered ionizing. UV-A is not. RF cannot carry enough energy to split nucleotide bonds. Unless we are talking colossally-massively-outrageously high amplitude RF, that is just how it is.
So then can we sue the fossil fuel industry for destroying our ozone layer?
Ozone does not block radio, it blocks UV.
Haha, good one.
Lets see if anyone figures out where that's from.
Yes, RF is non-ionizing. There is no argument there.
While it is interesting to discuss the finer points of UV (and thank you for linking information; UV-B/C is considered the margin of ionizing), really the question is whether RF can be dangerous at the amplitudes used by mobile phones. At this wavelength certainly not by breaking molecular bonds. I am also not aware of any significant absorption by organic materials (although I know little about 5G spectrum). Or put another way, a microwave oven is tuned specifically to the frequency absorbed by water and most microwaves output at around 1000W. Even if the phone were to pour all of its energy into a single “blast”, the resulting transmission power would be about 1-2 W... and not at a frequency known to be well absorbed by the body. Even if this transmission power could be maintained longer than that, it simply is not enough to add enough energy to significantly change any chemistry in the body.UVB is considered ionizing by who in what context?

The Nuclear Regulatory Commission specifically calls UV non-ionizing (but X-rays ionizing, so it's not because they're looking at particles rather than EM):
https://www.nrc.gov/reading-rm/basic-ref/glossary/ionizing-radiation.html
If you are saying that sunburn and skin cancer are caused by ionization, we have an argument.
https://www.bioscience.org/1997/v2/d/soehnge/3.htm
UV causes DNA lesions by photochemical reaction, not ionization:
https://en.wikipedia.org/wiki/Pyrimidine_dimer
So, while I agree UVB may be classified as ionizing from a purely chemical perspective, from a biological perspective it's the non-ionizing UVA and UVB that do the harm.
Yes, RF is non-ionizing. There is no argument there. It doesn't take ionization to cause tissue damage, that's just how it is.
I'm sure that all those $500/hour legal types will be using phones made by other companies. Anything but the companies named in the lawsuit. The same has to go for their computers etc etc etc. They have to be seen to be squeeky clean.I will bet a pound to a peanut that all the law firm lawyers will still use their own phones as if they were safe. Would make for a fun counter defence if caught on video.
Watched and not particularly impressed. She claims that cell phones use the same frequency as microwave ovens and the only difference is power. This is incorrect, they operate at different frequencies (though both are classed in the microwave spectrum). Furthermore, the claim that the cell phone can “heat up the brain” is preposterous. Even if a mobile phone transmitted enough power to heat the body (which it does not, I mean come on use some sense here, the battery is only ~3000maH), the body has this thing called blood and like a liquid cooled heat sink, it can carry away heat to closely maintain temperature. The rest was similar hysterics and junk science.In regards to EMF and the people saying it's safe. I will leave this here.
Though it's only for the logical intelligent people out there

Uh, not to be snarky, but did you even read my post or the study itself? Your attached screenshot shows the results in mice. As I said, results were equivocal in all mice and in female rats. However, there was a clear association between exposure and cancers in male rats.Did you even read those reports? Even the authors had to say results are “equivocal”. In fact, the control group had a lower survival rate than ANY of the experimental groups.
American regulators largely abandoned the precautionary principle because they considered it too much of a burden on businesses to prove the safety of new products. Now we just wait for people (sorry, “consumers”) to start complaining of harm before applying any sort of scrutiny.It surprises me how many surprisingly stupid people here disapprove of this lawsuit because "there's no proof it harms humans".
The absence of evidence is not evidence of absence. I'm not interested in rolling the dice with radiation just because some companies can't abide by the rules.
As another poster mentioned the FCC sets the standard, they review and test manufacturers claims and then grant approval for the device to be sold and used. If anything this is the FCC responsibility and not to just rubber stamp anything and everything. I am not taking sides just pointing out where the lawsuit should be targeted.
Let’s say Apple and Samsung are found guilty, those two companies will just sue the FCC for its role to approve.
I wonder why nobody freaked out about this in the 80s and 90s when analog cellphones were transmitting an entire watt or more ERP, yet nobody got hurt by that. Modern phones put out a tiny fraction of that, and people are freaking out.
I'm so tired of this excessive paranoia.
Warming your hand with a hand warmer is a fundamentally different process from warming it with microwaves. The warmth of a hand warmer enters the body via diffusive processes from the outside, something our body is well-adapted to. We have mechanisms such as sweating or regulating blood flow in our skin to adapt to that. Microwaves on the other hand are very penetrative, so you'll heat up your body from the inside. That is something the human body is well-adapted to. Whereas your skin can carry excess heat away pretty effectively, some random cell in your brain can't really do anything about it except wait for diffusion and blood flow to carry the excess heat away.There's a lot of dumb on the internet, so some simple napkin math:
The iPhone XR has a 12 watt-hour battery and 25 hours of talk time. So, assuming you've got the phone plastered to your face, which you'd pretty much only be doing if you were talking on it, and also assuming that, miraculously, 100% of that wattage is going into the radio signal going in and out, that's half a watt of electromagnetic radiation.
A consumer microwave, which, you know, cooks food, runs from 1,000 to 2,000 watts while active.
This is like worrying about your electric hand warmer burning you because it uses the same heating coils as a space heater.
... actually, the hand warmer is actually a much bigger risk than a phone 'cause it typically eats 20 times as much wattage to generate its heat as the previously-mentioned XR, and the infrared electromagnetic radiation coming out of it is in the terahertz range, literally thousands of times higher than a cell phone radio's gigahertz range.
For whatever reason, I think we'll all be fine and the current stateside limits on electromagnetic power are bloody stupid.
Do you have proof of that?So tired of people freaking out over RF, which is harmless. Reducing RF emission will reduce the performance of the phone since the tower won't be able to receive it as well!
