Hi Henrik

I think it is approximately 30 feet height difference between our flat and the tower flat panels. horizonal distance between my flat and the tower is 20 feet. How to know whether flat panels on tower are pointing towards my flat ? I can send the photo of tower viewed from our window. can you give your mailid.

Thanks
ST

Hi ST,

My Name is Abhinandan.
We do the shielding of cell tower radiation.
if you cannot remove the tower then you can easily block the radiation by using our products and stay in radiation free homes.

mail me your contact no. on: nesa.abhi@gmail.com

I will call you personally and will explain you in details.

Hello
I have a question. I am a parent living in US. The High School that comes in our Zone has installed multiple cell antennas on their Choir(music) Building. I am very concerned. My kid is not in Choir but there are classes around the Choir Building.The antennas have also been painted brown to blend in with the bricks. Is there any diagram showing how much area comes under the thermal and of course non thermal effects of these antennas?I wish I could post a photo here to make my question clearer to understand.

MimiWray,

Cell antennas are fairly directional so they "focus" the radiation towards a direction. This is known as "antenna gain". The radiation plume from a cell antenna is usually plotted as a vertical and horizontal graph showing how the radiation is distributed into its surroundings. As an extremely simplified concept, you can imagine a flashlight beam that's slightly tilted towards the ground and where the beam hits ground, typically, 60 - 200m away from the position.

In reality, its more complex. In the vertical plane, the distribution of a cell antenna is "flower" shaped and in the horizontal plane, it looks most like an "apple" shape - if you can visualize that.

There are images on the following link that illustrate what it looks like:
http://www.raymaps.com/index.php/antenna-radiation-pattern-and-antenna-tilt/

Due to the "flower" shaped vertical distribution, there can be so-called "side-lobes" which are narrow beams that shoot downwards close to the base of the antenna. Side-lobes can be just as intense as the main beam itself. If the antenna is mounted on a roof, people stationed underneath can be exposed directly to those.

The size of the thermal and non-thermal areas you ask about depend on the antennas power output of course but the industry itself claims that its safe to stand 2 meters away from a cell antenna. I doubt, however, that they've factored in the antenna directionality (gain) in that statement. The industries view of RF safety is only in preventing heating of tissue and internal burns.

Re non-thermal effects: if you assume that the basestation as a 10W output power and a 7dB gain (typical for urban antennas) then you'll have to be at least 1146 meters away from the antenna in order to be within the BioInitiative 2012 biologically-based exposure guidelines. If you want to be within the German building-biology SBM2008 "no concern" limits, you'll have to increase your distance to at least 7514 meters.

I hope this clarifies. If you have questions, don't hesitate to ask.

PS: Thanks to Kim Horsevad for presenting the above calculations in his book on RF and health (ISBN: 788740912418)

Hello Experts,

I an staying in Pune and there is cell tower near to our building approx. 30 feet distance from our building, but there is no flat panels towards our building direction (one circular part is our direction) and my flat is opposite side of the tower side flat (my flat is on 5th floor (total 7 floors) and tower top is on 7floor level) so is it safe ? please suggest.

Pune_99,

Since the flat panels radiate in a vertically directional fashion, you'll get somewhat less exposure than if the panel if facing you. But considering that the horizontal pattern of the flat panel radiation is "apple" shaped, you might be in its zone if you're at a similar height and the flat panels have a downwards tilt.

Typical vert./horiz. radiation patterns for a cell-tower panel are shown on the image at this link:
http://www.raymaps.com/index.php/antenna-radiation-pattern-and-antenna-tilt/

The circular parts are so-called point-to-point microwave links that daisy-chain cell-towers. They are more intense than the flat panels but also very directional. They are of course not like "lasers" so they can have up to 30 degree spread of their main-beam. This can expose opposite buildings.

Really, I wouldn't expect only 30 feet distance from a cell-tower (in any direction) to be biologically safe - but without proper measurements (peak, not average), I really can't evaluate the situation.

best,
Henrik

Hi Sir

Today I was at the roof of a building where a mobile tower is installed. The panels of the mobile tower were rectangular in shape and was at a distance of 8 meters horizontally and 2 meters vertically from where i was standing. I was at the roof for about 5 minutes. Is there any health hazard associated along with it. Also note that the rectangular panels of the mobile tower were not directed towards me. In other words i was standing at the back of the panels at the specified distance.

Will this cause any damage to my health?

Thanks

sanbiz,

Microwave exposure always carries a health risk. Even at low intensities, microwaves can cause oxidative stress in cells - which can lead to up-regulation of free radicals and thus tissue and possibly DNA damage.

If you were only within 8 meter distance and facing the back of the transmitter panels for 5 minutes, I'm thinking you've probably not sustained serious, permanent, health damage. The radiation from the rectangular mobile-tower panels is focussed towards the direction the panel is facing. Just standing there, you'll get far more exposure than the independent biologically based guidelines will recommend, but you would likely not exceed the official thermally based guidelines that only protect you from tissue heating within 6 minutes of exposure.

If you click here you can see a graph of the radiation plume from such a tower panel. This graph is taken from the tower panel manufacturers brochure.

To lower your bodies oxidative stress from the event you can take ordinary vitamin C and E supplements, which have been shown in studies to reduce DNA damage in microwave exposed animals. Please note that this not medical advice and speak to your doctor if in doubt.

Be aware that there can be delayed health effects, like dizziness, confusion, vertigo, skin irritation and similar neurological problems. If they persist, see your medical doctor.

If you have symptoms and your doctor is unaware of the health effects of microwave radiation, then please refer your doctor the European Environmental Doctors EMF guide for the prevention, diagnosis and treatment of EMF-related health problems and illnesses:

Just a bit of further technical information...

Using standard parameters for a macro cell installation the power density for the dominant frequency should be about 1,2 W/m² at the backside of the antenna in the distance you stated. Be aware that this is based on standard installations with standard parameters and no reflections.

Hi experts

The duration of my standing at the roof was not accurately measured. It can be 10 minutes also but not more than that. Apart from that there was a wall in between the mobile tower panels & me. But this wall was not continuous. Hence it will be only 2 to 3 minutes that i was exposed to mobile tower radiation directly without any barrier.

I donot have any health symptoms as such. But am worried. Would like to about the precautions to be taken now.

sanbiz,

"there was a wall in between the mobile tower panels & me"

If possible, can you describe what material the wall was made of? Building materials have different reflection and absorption characteristics.

Respected Sir

Kindly note that the wall was made of concrete & partly of wood. But the wall was not continuous. So while i was walking on the roof top there were a couple of instances where I had direct contact with the mobile tower panels at a distance of 8-10 meters horizontally for 2-3 mins. Rest of the time(ie 5-8 minutes) that i spent on the roof there was a barrier of wall either made of concrete or wood between the mobile tower panels & me.

Also i would like to ask you about the health conditions of the telcom technicians who work at the sites of mobile towers. They also work near to the mobile towers for more duration of time than the amount of time i spent close to the mobile tower, So arn't they more prone to risks.

In my case the exposure was only at the max for 10 minutes in total but the mobile tower technicians work for more time duration at the mobile towers site. They also work much closer to the mobile tower panels at the time of their work i guess.

You also suggested to take supplements of vitamin E & C . is it alright if i consume foods & fruits that have high levels of vitamin C & E in them for a few days.

Also the graph that you send me shows that there is zero intensity of radiation at the back of the panels at a distance greater than 5-10 meters.

Kindly clarify

sanbiz,

The wooden wall won't shield you much from the microwave radiation, but the concrete - depending on thickness - would shield you somewhat. You can't predict how much a wall will shield. You have to stand there with a measuring device to get an exact exposure value.

Yes, telecom technicians are at high risk if they work on sites with active mobile-towers. Here in Denmark (where I'm based) we've been contacted by tower-workers who have been permanently disabled from exposure. Large insurance companies have also called work on mobile-tower work the number 1 "emerging risk" (click for PDF document). It is telling that the mobile telecoms can't get insurance coverage for health related damage and injuries. Try watching this short news video from America, where a tower-technician says he's suffered burns and severe neurological symptoms from exposure to mobile-towers:
https://youtu.be/6pzcuQw7XWY

As per the calculation in Kim's comment, the estimated exposure you'll have gotten while on the roof is below the thermal exposure levels (meaning: the level at which you can suffer radiation burns). There are, however, a long list of non-thermal effects that can manifest as a variety of symptoms - mostly neurological in nature (like the tower-technician mentions in the above video). Most common symptoms are: headaches, sudden onset of depression, confusion, vertigo, skin rashes etc.

About the graph:
One thing you must understand is that the mobile telecoms industry only acknowledges thermal effects from the radiation, no matter how strong the scientific evidence for there being health effects below thermal exposure levels. So what looks like - as you mention - zero radiation in their graph, will still give you significant non-thermal exposure - as per Kim's estimate.

About vitamin C & E (anti-oxidants):
Yes of course you can consume natural foods high in those vitamins.
Also, I'd suggest that you limit your exposure to other sources of microwave radiation to give your body some recovery time. Such other sources of continuous exposure are: Wi-Fi routers/access-points and cordless phones. Those radiate 24/7, irrespective of use. Sources like mobile-phones, iPads and other Wi-Fi enabled gadgets give you intermittent exposure, when in use. Beware that modern "smartphones" with data-apps installed, can cause exposure when transferring data in the background. Keep such gadgets at a distance from your body in any case. The manufacturers safety guide even says so (click here for example iPhone safety guide).

Hi Henrick

I live in Pune, India. Near our flat there is a mobile tower approx 80 meters away. But the level of the mobile tower panel is same as my floor of the flat. In other words the vertical distance distance between the mobile tower panels & my flat is 0 while the horizontal distance is approx 80 meters.

Also both the mobile tower panels are facing my bedroom window. Even though the panels are located at a distance of 80 meters away from my flat will it be safe inside my home.

Also does the mirror reflect the radiations back.

Kindly suggest

Expected exposure values for the the dominant frequency in stated distance from a typical macro cell antenna tower would be around 40 mW/m² (= 3.8 V/m).

This is a rather high exposure. Mitigating actions are strongly warranted.

Ideally exposure values should be below 0.0001 mW/m² (= 0.1uW/m² = 6.1 mV/m).

Mirrors might reflect - the reflection depends on the amount and orientation of metallic components in the mirrors backside.

Dear Sir

My house is within 50 mtrs from four mobile towers.
Is it very danger to stay in the same place ?
is there any Radiation Resisting System available in Dubai ? If yes, kindly let me know where and price details.
Also, if the radiation detector available, availability and price please.
Kind regards,

Buildings can be shielded with paint from Yshield:

A suitable measurement instrument could be:

Be aware that it will be a quite massive undertaking to satisfactory shield a building down to habitable levels with such large exposure values.

Hi,
I stay in Bangalore,I recently moved to my new flat which is in 2nd floor(20 feet from ground).There is a mobile tower with 6 rectangular antennas with its base station installed on ground, and these antennas heights are around 25 meters from ground.I stay around 90-110 meters from the tower,Does it really causes health problem?
These rectangular antannas are not exactly pointing in our direction,but they are at an angle of 10-15 degree.
I have a kid of 2 years.Is there any problem to the kid?
How to reduce the effect of radiation on our family.

Some 95% of the available scientific literature indicate elevated levels of free oxygen radicals when model organisms are exposed with pulsed microwave radiation in similar non-thermal intensities.

As such, there is a definite risk of adverse health effects.

It is possible to shield a building, but in such close proximity to a antenna mast such shielding projects will be costly and labor-intensive. Sometimes it is easier to move to a safer location.

Shielding paint can be bought online:
Yshield HSF 54

Proximity to the mast is very dangerous. I never had any problems with Radiofrequencies until I took a job, with a window office that overlooked a cell tower 250 feet (~85 meters) away. My health began declining immediately, within 6 months I was ill whenever I was in the office and by 12 months, I developed intense physical anxiety and heart palpitations and insomnia. Within 13 months I was able to feel cell tower radiation driving down a road and highways became uncomfortable and I developed full on RF sensitivity. It definitley came from that mast near my office, my head felt like it was stuck in a microwave when I sat there, and I felt better on the other side of the building. I had to make arrangements to work from home - my life is ruined because of being direclty in the main lobe of that mast and the future only looks worse with 5G coming.

Thank you Horseved.
If we go for shields,how much are they reliable?
And the other point is, on the tower it is written as,Non-Ionizing radiation and Violating the human laws of radiation.What does it mean?Non -Ionizing radiations are less harmful?(This tower has only rectangular antennas)

Just opposite to the tower, a big water tank at a height of 15 meter and has a diameter of 8-10 meter is installed.And from terrace which is at a height of 50 feet I cant see the tower because the water tank blocks the tower.

If We want to measure the radiation levels at my home to whom should we contact?
I stay in north Bangalore.

And how do I know the power levels of the radiation and also the gain?


My home is surrounded by two more towers which are around 150 meters away(In other direction-left side of my building).These towers have both circular and rectangular antennas.

Shielding works quite effectively when applied correctly.

My own electronic lab/workshop is completely shielded - even to the extent that a normal FM-radio cannot tune to any station. This level of shielding is achieved with aluminium fly-netting.

Read further about shielding here:
Shielding FAQ

Before you start any shielding project you will need to invest in some kind of measurement tool, both in order to evaluate the need for shielding and check the effectiveness of the shielding.

I recommend the Cornet ED88T
