good evening my name is felicia michalek
I’m 17 years old and I ‘m just doing mine
high school in hamburg together with my
Unfortunately, my sister is not here today
I have been able to do that for several years
effects of cell phone radiation research
with the project I give them today
I have to imagine that
scientific competition
Youth research participated
Did you know that now 80 percent
the German own a mobile phone
I am sure that each of them
has a mobile phone and it too
regularly used to, I have them
brought a bed this shows one
Head with a mobile phone on his ear
what do you think when you see this picture
see the colors on the head
see are the intensity of a
radiation from the phone during the
go out on the phone
Here is the heat radiation shown
which emanates from the cellphone am curious
whether you like this picture after my presentation
from a different perspective
then have a sister and I
we think about how we get the mobile phone radiation
we can examine humans
for once excluded because yes
Do not try on people
can
That’s why we came up with plants
that ‘s what I’m going through in the course of my life
lectures answer the question
plant by cell phones and wireless router
Stressed to answer this question
We may have some before trying
performed for an optimal
develop a test setup
We wanted the results to be good
compare and reproduce
it turned out that the best
try beans as you can here
able to see
pea beans and cress for disposal
stand
Because these germs grow fast fast
and are easily in large numbers
The result then looked like this
we have the natural ones about that
environmental factors which are responsible for growth
the plants necessary are exactly the same
We have two plexiglas
built boxes and there two to three
No boxing set as you get here
able to see
the green ones we have
with exactly the same earth with exactly
the same number of seeds from exactly
the same bag planted with exactly
poured the same amount of water
through a lamp construction the man
unfortunately can not see here now
we could ensure that the
Plant exactly 14 hours a day
be irradiated light
thus we could have disturbing factors
that could influence the results
have eliminated the only difference
It was that over at the first
general meetings page the main
Try from 2011 to 2012
have that there again we have there
Handy uses the modern at the time
were
see them down there by us
did not even know if any phones
have an influence on plant growth
We first with a mobile phone
started and have the number in the course
the trials have increased in parallel
we have a control trial or one
run control group so that we
compare the results
at the second try we from 2014
we have done until 2016
another third came plexiglas box
placed next to where we have one
have set up wireless router and
exactly with mobile phones the attempt
have done and have there as well
we used a control group
in the course of the experiments we have the
single plants on germination and
observed on the growth in length
mostly in a period from 14 to 17
days and random samples of the
blood number of individual plants
determined and the water consumption
detained and conspicuous
growth behavior
characterized until more than 60 data 6000
we created in tables and
have worked out diagrams and
then analyze it
Overall , that resulted in planting
where the phones with in the box
later germinated and slower
grown as the plants
where no cell phone in the box stood around
To be precise was the effect
the first main station tried
greater
there were, for example, the stems
weaker and the leaves smaller and
brighter, for example, you have here
Below in the picture an area seen
where almost no plants are known and
also here up here example
exemplified four tables
or count said where the red count the
control group is we as 100
percent and green
there down from the average
growth of which shows mobile planting
at the first try up here in the
corner one sees that we there only one
mobile phone used
because there the difference was 10 5 percent
on the second try with two mobiles
up here you can see that they are the club
already bigger 15 percent
down here with three phones or even
already 20 percent
and with four phones 24 percent 26
percent so you can say that ever
More cell phones in the cash registers were the
difference was also greater in the
second try you have a lower one
try a lesser difference
seen at the cellphone for example
There was a difference of five to ten
percent on average
but it was terrifying to see them there
results of the wlan router
There was, for example, in a quarter
circle the growth is completely gone
Here, for example, one is about there directly
standing right of wireless routers there
nothing grown
there in the case of the second main
We noticed overall
that distance affects the
We have growth in length
our measurements are divided into two parts
here that red line does that
clearly where we once to 15 centimeters
away from the radiation source
have measured length growth and
once from 15 centimeters to 30 cm
We will have that in these tables
and graphs
and there are clear differences
you probably also see from further
behind that again the red graf
the control group is the 100 percent
again , the green represents the with the
cell phones and the blue ones with the wifi
and you can clearly see that the
difference is greater in the names
plants than those further afield, eg 24
percent and 5 percent and 62 percent and
10 percent
Here you can see the intensity of the
radiation of our once from the
devices we have used
up here are the new phones
the on the umts resp
lte standard and on one
unused procedure that is it
in standby mode not so much anymore
radiate as opposed to the
older phones on a gsm
standard and based on one
pulsed method
there is the connection to the
example, including radiation
richer and lower to see where
most of the radiation emanates from the
WLAN router
this is based on a pulsed
process and even radiates
much more intense than the older ones
mobile phones
Here we have the radiation intensity
can measure with a field strength
meter where we are here now
for example, the wlan router
have shown and up here in the corner
when at the top of the mountain if
remember the cress was there
not known exactly in this
quarter circle where the highest
radiation intensity was nothing
grown
the results I give you
Love has just shown you
have now only on the outside
therefore limited to the plant
a sister not considered and
tries to prove that also in the
plant change by the radiation
have arisen
there we are after intensive research
on an overproduction of reactive
oxygen species come
that means planting on stress
react with overproduction
Stress can be extreme among others
be temperature differences as extreme
heat and drought but also strong
Ultraviolet radiation can cause stress
and what the rebellion electromagnetic
radiation emanate from cell phones
this overproduction makes gives the
an imbalance between
oxidants and antioxidants in the
plant arise what in turn to
cell damage leads we have it there
a trance that means brad
pretest with which you can
production of toxins
We were allowed to do this on the biology
institute of the university hamburg
carry out
There we have single plants of
harvested our test series directly
frozen and then there the try
carried out
down here in the corner are the
results to see the congruent
with the results are from the
try before or from the measurements
before that is the wlan plants are
for example, the lowest grown
and had the highest protein amount
in there
In summary, one can say that
we try with simple and
could show measurements on plants
that cell phone radiation is the growth of
Plants affect the assumption
So is close to that this one that
Cell phone radiate an influence
electrochemical processes in the cell
I especially like that
negative for growth
just in the co-phase is now affecting
of course the exciting question is if that
also us humans is transferable
and whether we humans also through
be influenced by mobile phones
could
a direct transferability is not
possible but also in the human
Body run electrochemical processes
From the radiation of cell phones
could be influenced
So what do you think now if you have this
head and know that not only
thermal radiation emanating from the mobile phone
if you remember the cress the
in the direct vicinity of the wireless router
is not up to it and if it is you
if you think about it at the
Most of your phone calls directly to your phone
take her ear and thus her brain directly
with electromagnetic radiation
expose
my sister did not care
how we think about the mobile phone radiation
avoid unnecessary cell phone radiation
can in our everyday life
there are very simple things for us
come in for example during
the call setup, the mobile phone in the hand
take and not on the ear at there the
radiation intensity is highest
or not in the car phoning where
we are in a closed room and
the radiation intensity thereby also
again is significantly higher but on
Of course we would find it the best
if the phones we use
phoning such a low radiation
that they do not harm us
So are not against the use of
mobiles because we have a total benefit of
they have but we need more in
thus the research invest
the effect of the many radiate us
surrounded daily
for us humans further investigated
because we all want negative
Long-term effects of radiation for us
people and avoid and the technology
Of course we all like it very much
should also benefit us and ours
live well
Thank you for your attention
[Applause]
