OnePlus 6T, OnePlus 5T, Mi A1 found among smartphones emitting high amount of radiation

Watts per Kilogram?  Kilogram of what?  Kilogram of phone?  Kilogram of head?  If so, who's head weight are we using?  Lol.

 

I really hate it when units of measure are not specified completely.  

 

I'm an Electronics tech and HAM radio operator, I regularly operate MF/HF in the 400-500 watt range, VHF/UHF in the 40-60 watt range,  and I'm usually less than 10ft from antennas while I'm doing it.  I'm not worried about the 500mw of UHF that phones put out.

Hm, so aka the phones with the best and worst signal strengths respectively?

 

I mean really, if they're not going to say specifically which frequencies they're looking at (or what type of radiation really, but I think it's safe to assume it's EMR in this case and not nuclear like alpha particles or something) then this data is both useless and makes them look stupid.  Obviously phones give off and receive radiation, it's called wifi, bluetooth, the cellular connection, etc.  Joking aside, the more or less you have of that literally is just how good your signal is, so unless certain devices are putting off a lot more of a kind that isn't useful for anything and could otherwise be avoided, the "high levels" are unavoidable and not even necessarily a bad thing.

lol at all these people who apparently think that using a cell phone is like walking around holding a brick of weapons grade plutonium to your head...it's a shame that physics classes aren't mandatory...

Is this bad????

Per kilogram of death radiation, obviously

Only if you're a nutter, in which case adjust your tinfoil hat accordingly

So this is actually ionizing radiation or is this another one of those "aahhhhahhh visible light is causing cancer! I better wrap a blindfold around my head so I can't see the light that's causing me cancer" stupidity?

never mind, it's one of those "visible light is causing cancer" stupidities so we're all good to use smartphones as much as we want without any cancer side effects.

Don't blow it off completely though - non-ionizing radiation can still mess you up.  That's what your microwave uses to heat up your hot pocket. 

 

Now, we've only been using radio waves for interesting purposes for about 120 years.  For most of that time, the majority of humans were not absorbing RF radiation at a close range.  It's only been since the mid 90's when cell phone usage picked up.  30 years is not quite long enough for "We're certain".  It's barely long enough for "we're kinda pretty sure" that holding a 500mw transmitter against your brain ain't gonna cause any funky stuff if you do it for a few hours a day every day for a lifetime.

I mean, it's **probably okay**, but there's always going to be doubt.  

Personally, I hate that they're putting X and K band radar systems in cars now for collision avoidance - not only does that crap set off my radar detector, but as a former Navy Radar Technician, I know what those frequencies (Even at low power levels) can do to your eyeballs and testicles.    Now you're strapping equipment to cars that could theoretically put off much more than expected power levels, and no regular maintenance to check it.  

Some of those cars (GMC/Chevy Equinox/Arcadia/Suburban / etc  - Newer Audi's) will set off my radar detector at 3/4 of a mile behind them.  That's about the same distance it gets set off by actual police radar.  That's too much power to be blasting everyone around you 24/7 imo.  Others (of the same model) don't set it off until I'm within 100 feet or so (What I'm imagining is the proper distance / power level).  I really doubt anyone is doing a power output check on these things at dealer services.

body weight.

That can't be right.

 

Most phones I'm aware of do not pass 700mW peak envelope power.  There are examples of older mobiles going as high as 2W, but never more.

 

If it were 1.6w/kg of body weight, that would mean a phone would be around 120-180+ watts.

 

 

Doing more research, it appears that the FCC measurement requirement states "phones sold must have a SAR level at or below 1.6 watts per kilogram taken over the volume containing a mass of 1 gram of tissue that is absorbing the most signal"  - So they use a single gram, and scale from there. 

 

That makes a bit more sense.  The original article should include that tidbit lol.

 

They must use a measuring device to pinpoint the SAR of each device instead of just going off of it's actual power output, as antenna placement, size, polarization, and other factors could play into a much higher SAR on one device vs another that have the same output power.

So what do you guys think about this? post your comments & thoughts down below, comment on whether you were surprised to see the results coming from the major retailer so high & so so low on the list, especially one plus.apple & Samsung having contrasting difference.

Mess you up, sure. Give you cancer, almost certainly not.

Great post. Very thorough explanation 

[rcmaehl]

Fake News!

 

But yeah, a lot of things emit radiation. Big differences are the amount and Ionizing vs Non-Ionizing. So far there has been nothing to worry about and I doubt there will be anytime soon. Things such as CRTs and Bananas emit more radiation than you'd ever get with a smartphone.

 

Regardless, this radiation measurement is probably a good way to measure phone efficiency; if your phone is wasting battery just outputting radiation, it's probably not too efficient. Looking at this chart, it appears the top offenders of radiation are Snapdragon chips, and the lowest offenders are Exynos chips (including the Note8 since it's likely the Exynos International model because Germany).

 

Honestly, unless a specific cell phone is outputting a significantly high, abnormal amount of Ionizing radiation, there's nothing to worry about. This is the same scary info that makes people freak out about 5G's 60GHz, when if it was an actual issue we'd all be dead from SETI, Pay Per View, or Amateur radio by now

every time someone tells me not to stand in front of the microwave or I'll get cancer I want to punch them in the face.

1. It's not ionizing radiation

2. The wavelength of microwaves is 10cm and the holes in the door are like 1mm. that's a 10.000-fold reduction in radiation outisde the microwave compared to the inside.

 

Hell, eating a banana is way more radioactive then standing a meter in front of a microwave. Ignorant people are the problem of this world.

Wouldn't help if they where in a lot of cases. A lot of people are really poor at remembering facts and figures.
