Effective shielding for mobile phones?

Dear all,

I would be very grateful if someone could point me in the right
direction about mobile phone shields. I'd like to understand how
shields can be effective during normal call use. My confusion is that
shielding could attenuate signal strength which could cause the phone
to transmit at higher power.

With thanks,
Sandy

Hi Sandy,

There is a lot of confusion about cell phone shields.

There are 2 points to remember:

1- the entire phone radiates, not just the antenna
2- depending on the design of the phone, a certain % of the radiation is
absorbed by the user's head. This radiation is not useful for the
communication. Ideally, the shield should shield this portion of the
radiation, and still allow the balance of the signal to radiate outward, if
the phone is still to work.

Now, notice this: if instead of encountering a nice absorbent head and being
"wasted", the radiation encounters a nice reflective shield (between the
head and the phone), then you are not reducing the performance of the phone,
you are actually improving it.

Notice further, if you shield the side of the phone away from the head, you
will reduce performance, and increase radiation to the head.

I agree completely with Emil. Those little beads others sell are probably
a waste of money. If I had to hold a shield to my head, I would certainly
want
a shield that covers the whole phone (and lessemf sells them). I'm not
sure about the relative merits of that kind of shield, versus speaker phone
mode, versus a wired head set (preferably with air tube). But I no longer
feel safe with a cell phone on within 10 feet of me. Even with a perfect
shield there is potential for reflections, plus damage to people near you.

Pagers that only receive should be considered. Also, there exist (I think)
infrared head sets, although the one I saw advertised was for car use
and not actually in stock.

I would not mind at all. Also, I feel like when my symptoms were at their
worst, I became sort of autistic. It would not surprise me too much at
this point if the main cause of autism was EMF exposure (see George
Carlo's comments<http://www.lef.org/magazine/mag2007/aug2007_report_cellphone_radiation_01.htm>in
Life Extension).

I've done some experiments with shielding
cell and cordless phones. The conclusion
reached is that the most effective shield
covers the entire circumference of the phone.
Shield just one side and you'll lose a
majority of RF attenuation. In my honest
oppinion these gadgets (beads, gold plated
trinkets, etc.) aren't worth the paper
they're packaged in.

When expressing an opinion such as this, it
would be good to know exactly what
sort of personal experiences you've had
with these gadgets before reaching this
conclusion. Many times, people just dismiss
things without doing any personal research or
experimentation, and as such, these opinions
aren't worth the keystrokes they're made
with... :-)

Me? I have done some experimentation with
cellphones and gadgets, but not much,
because I don't really use my cellphone
that much. I can say that Springlife
polarizers do seem to help, although these
don't need to be next to the phone (in
my pants pocket is good enough). These
also are helpful for when using a digital
camera.

Based on my experiences with gadgets and
computer monitors, I would also say
that the RADAR card, BioProtect card,
and Quantum Companion would also be
good candidates for gadgets that could
reduce adverse reactions while using
a cellphone.

(I don't have much experience with beads
or gold-plated trinkets) :-)

Marc

Guilty as charged.

Allow me to restate, without expousing
sweeping generalizations...

It has been concluded through by my own meager
experiements that when shielding cell or cordless
phones with mu metal, the most effective configuration
is to cover the entire perimeter of the phone,
and antenna. Shielding only one side leads to far
less RF attenuation.

Eli

I have had problems of all sorts on the left side of my head (left ear has infections, left eye very bad sight, left jaw joint has dead tissue, left sinuses impacted, teeth worse on the left side...) Maybe we are onto a trend here? Any one else?

Hi M,

hAVE YOU EVER GONE NEXT DOOR AND CONFRONTED PERSONS CARRYING OUT THE WORK ?
any chance that they might have installed an antenna in the chimney ? Sounds

Thanks Sandy for the useful snippet of information:
(Many of our most
immune damaged children seem to be electrosensitive).

This ties in with a lot of the evidence accumulating in this and other
groups that immune system problems and related illnesses are often a trigger
to electrosensitivity (in adults as well). Conversely, treating the
underlying illnesses (when identified, which is often difficult) seems to
have helped reduce ES for many people in the group.
This might link to possible treatments to alleviate autism.

This is particularly interesting to me as many autistic children report improvement on a gluten free diet, also! Infact, one of the most useful sitesI use as a celiac, is a site devoted to autistic children: www.gfcfdiet.com

Dear Ian and Diane,

I was struck by the similarities between effective ES therapies and
autism treatments www.treatingautism.com
http://www.autism.com/treatable/index.htm. The therapies mentioned as
useful for ES sufferers - probably because they are treatments for
the immune system - are very familiar to us.  

This is a summary of "biomedical" autism treatments (there are also
some useful rated results
http://www.autism.com/treatable/form34qr.htm#biomedical). Many
vitamins, aminos and minerals, especially B vitamins and magnesium
and zinc, are typically very low. Treating IBS and accompanying
bowel infections (clostridia, yeast, strep and usually several more)
is an on-going challenge for us all. Detoxing the home environment
is very important. Generally the more old fashioned things are the
better. The GFCF diet - also soy free, corn free MSG free is often
the first big improvement. We found the SCD - specific carbohydrate
diet - and "Nourishg Traditions" has helped us. Probiotics and
fermented foods are good. Digestive enzymes (Houston) regularly
have impressive results. Getting B12 up is important as is
supporting methylation and sulfertransferase and detoxing heavy
metals (almost all our children had the mercury preserved vaccines
starting at 6 weeks of age). Our son has "remarkable mercury
toxicity" reported by porphyrin testing (... what have we done to our
children). Thyroid and adrenal support, cranial ostepathy, lymphatic
drainage and EPD for help with allergies and brushing or exercise to
help with retain reflexes and hyperbaric oxygen treatment - are also
useful. Sadly our NHS medical services are a long long way from
helping with much if any of the above. It is therefore very very
expensive but many of our profoundly autistic children are healing
and many too are recovering. Our little boy, Eddie, was early onset
autistic and has been very ill for most of his life. He is now
almost 4 yrs old and passing for normal on good days. We have a long
way to go to improve his health but we have seen the most profound
transformation - and we were told there was nothing we could do to
help him.  
Best wishes,
Sandy
