00:00:00.080 --> 00:00:06.960
a while ago we did a video on whether smartphones could actually cause cancer

00:00:05.040 --> 00:00:11.440
from the radiation that they give off in the form of cellular and wi-fi signals

00:00:09.519 --> 00:00:15.920
you can check it out up here but the main takeaway is no you don't

00:00:13.840 --> 00:00:20.800
have anything to worry about but here we are in 2019 and some of the same

00:00:18.160 --> 00:00:26.080
concerns are getting raised yet again this time about 5g

00:00:23.680 --> 00:00:30.560
although 5g promises to deliver faster speeds to our phones and there are even

00:00:28.480 --> 00:00:34.399
home-based internet solutions that use 5g

00:00:31.760 --> 00:00:38.879
the fact that 5g travels over higher frequency radio waves has led to

00:00:36.559 --> 00:00:43.600
speculation that it might be riskier to use than older generation wireless

00:00:41.120 --> 00:00:46.960
standards so how much truth is there to this and why are people concerned in the

00:00:45.680 --> 00:00:52.399
first place well to start with 5g uses what's often

00:00:49.760 --> 00:00:57.760
called millimeter wave frequencies which are shorter than the typical frequencies

00:00:54.719 --> 00:01:00.559
used by 4g and wi-fi signals and

00:00:57.760 --> 00:01:06.880
therefore higher in energy in fact while lte can use frequencies of

00:01:03.680 --> 00:01:09.600
around 2.5 gigahertz and wi-fi often

00:01:06.880 --> 00:01:16.799
works on the 5 gigahertz band millimeter wave frequencies used by 5g can be up to

00:01:13.080 --> 00:01:19.680
300 gigahertz so we're not talking about

00:01:16.799 --> 00:01:24.960
like a small incremental leap here so then could all this extra energy end

00:01:22.640 --> 00:01:29.680
up being harmful in ways we haven't seen before well some of the folks and

00:01:27.280 --> 00:01:33.520
advocacy groups that believe it is point to actions taken by the

00:01:31.520 --> 00:01:39.600
international agency for research on cancer or iarc specifically the fact

00:01:37.520 --> 00:01:45.040
that they've classified rf electromagnetic fields in short radio

00:01:42.000 --> 00:01:47.759
waves as possibly carcinogenic to humans

00:01:45.040 --> 00:01:53.040
as evidence that it is well that sounds pretty alarming doesn't it

00:01:49.840 --> 00:01:55.200
well it might until you consider that

00:01:53.040 --> 00:02:01.200
many things that most of us find innocuous like a cup of coffee actually

00:01:58.479 --> 00:02:07.680
fall under exactly the same category you see if you dig into what the iarc's

00:02:04.000 --> 00:02:10.319
definition of possibly carcinogenic is

00:02:07.680 --> 00:02:14.160
they mean that there's only a limited amount of evidence that an agent might

00:02:12.640 --> 00:02:17.920
cause cancer so there might be some kind of weak

00:02:16.319 --> 00:02:24.239
correlation that's been observed in studies but that is a very far cry from

00:02:21.280 --> 00:02:28.800
there being any kind of real causal link that's been found

00:02:25.760 --> 00:02:31.440
so irc's approach is to err on the safe

00:02:28.800 --> 00:02:34.800
side with anything that it classifies a bit like how

00:02:32.800 --> 00:02:38.879
everything that you buy has a label on it saying the state of california thinks

00:02:36.640 --> 00:02:44.080
this thing might cause cancer but this hasn't stopped people from

00:02:41.200 --> 00:02:48.879
hearing the words possibly carcinogenic and running with it in fact a couple

00:02:46.400 --> 00:02:53.040
places in europe were hesitant to test new 5g infrastructure

00:02:50.560 --> 00:02:58.239
citing health concerns and there were even rumors that there were widespread

00:02:55.519 --> 00:03:00.959
bird deaths in the netherlands due to 5g trials

00:02:59.200 --> 00:03:04.640
well turned out those birds were just eating poisonous plants i guess there's

00:03:03.040 --> 00:03:08.640
a reason that bird brain is an expression

00:03:06.159 --> 00:03:14.480
anyway the reason that we have nothing to fear from 5g is that radiation has to

00:03:12.000 --> 00:03:18.720
be much higher frequency to be what's called ionizing

00:03:16.560 --> 00:03:23.840
ionizing radiation can mess with the molecular structure of your dna and

00:03:21.040 --> 00:03:29.599
cause cancer the thing is the threshold for this is around a million gigahertz

00:03:27.040 --> 00:03:33.519
much higher than the 300 or so that can be used by 5g

00:03:31.200 --> 00:03:37.440
and at that point you're not even dealing with radio waves anymore you're

00:03:35.440 --> 00:03:41.760
dealing with ultraviolet light which is why sunscreen bottles talk about uv

00:03:39.599 --> 00:03:46.480
protection on the label now with all of that said we're not

00:03:44.159 --> 00:03:51.519
claiming that 5g or any other piece of technology that we

00:03:48.080 --> 00:03:53.120
use can't cause cancer or other health

00:03:51.519 --> 00:03:56.400
problems by some mechanism that we haven't yet discovered or don't fully

00:03:55.120 --> 00:04:00.799
understand yet the thing is though my advice would be

00:03:58.400 --> 00:04:04.879
to go forward live your life without too much fear

00:04:01.920 --> 00:04:08.720
and pick up that hot new 5g phone if you're into it now if you'll excuse me i

00:04:06.959 --> 00:04:11.519
have to go pick up a large sack of cash that the mobile phone industry left for

00:04:10.159 --> 00:04:16.639
me out back bye oh wait no actually the cache comes from

00:04:14.560 --> 00:04:20.720
