Testing The Safety Of 5G - BBC Click

dr. Richard Findlay is an

electromagnetic field safety specialist

and he's going to be measuring the

strength and frequency of the radio

waves at different distances from the

mast so first we're going to put the

probe right up on the middle of the

transversal yes

[Music]

maximum reading was 550 550 1.6% so

basically if you were to strap yourself

to that transmitter three meters up

there you'd be getting five times the

guidelines okay but no one's going to do

that okay so shall we go over there

which is what would you say there's two

or three meters in that direction and

see how the signal yeah yeah oh wow

fourteen point five so even over that

distance we've gone from we've gone down

by a factor of what is that that's fifty

five hundred and fifty down to fourteen

point five okay down to less than a

fifth of the government safety guideline

yes right time to try and make sense of

those readings with physicists and

cancer researcher David Grimes so we've

seen there that the power drops off

really really quickly as you move away

from the transmitter absolutely and

that's what you'd expect as you get

further and further away from a source

of light which of course radio frequency

really is even we can't see it the drop

off is really really rapid and by the

time you're you know even an appreciable

distance away from any kind of

transmitter it's way more likely that

your phone itself is going to be

emitting a lot more than Navy's

transmitters are do you think one of the

worries about 5g is that there's talk of

using higher frequency radio waves I

think absolutely I think people have an

intuitive understanding that higher

frequency is higher energy but I think

when people really need to be aware of

is that this kind of radiation is still

very very non ionizing what that means

is it doesn't have the fundamental

energy to liberate an electron and cause

damage if you want to cause say cancers

and things like that you typically need

to cause that kind of DNA damage

and the new 5g spectrum is very low

energy it's much lower energy than say

visible light but more than that the

biophysics itself the the mechanics of

how you might develop a cancer or

something we know that this kind of

radiation is non ionizing it cannot

cause the level of DNA damage that you

typically expect or need to cause a

cancer and so for that reason the

combination of epidemiological evidence

and biophysical evidence we don't have

any current cause for concern that being

said it's always good to observe and

keep an eye on trends to see what might

emerge but we don't expect anything will

so there you go some real science which

I hope has helped you to understand how

safe 5g signals are and just for extra

information we're now taking a reading

at head level here on the roof right

next to the 5g transmitter and the

number is kind of bouncing around the 2%

mark so even if you're walking on a

rooftop next to a 5g transmitter as we

are

you're still 50 times below the

recommended safety level
