All electrical and electronic equipment emit Electromagnetic Radiation (EMR), fortunately most devices do not emit high levels of EMR. The ones of prime concern are those that emit radio signals. These include but not limited to: Cell Phones, Cordless Phones, Laptop, Tablets, Baby Wireless Monitors, Wireless Routers. The laptop this is being written on emits approximately 25 milivolts per meter (Electric Field) when turned on, 25 more when the charger is plugged in and regularly over 1000 milivolts when on Wifi. To determine the Power Density would would also need to measure the amps per meter (Magnetic Field). Few radiation meters measure the Amps per meter. These regular meters calculate the amp reading based on established physics when the measurements are in the far field or at a distance from the source.

Yes this is a topic that few of us are aware of or understand on first reading. More explanation of the physics of Radio Frequency is in Cell Tower Siting Considerations. An excerpt on Near Field Radiation is in the pdf accompanying this article. The full booklet is available on request by contacting worksafe@sios.ca .

The radiation field around a transmitting device is divided into 3 primary zones: the Near, Far and a zone that is called the Intermediate or Transition zone – a blend of the other 2.


Safety Code 6 (SC6) Radio Frequency Exposure Compliance Evaluation Template (Uncontrolled Environment Exposure Limits) Industry Canada Technical Note-261

In the near field Spectacular peaks and Valleys of radiation intensity can occur, the radiation pattern is considered to be difficult to model if it is possible to model it. In the Radio Frequency Tool Kit For Environmental Health Practitioners by the BC Centre for Disease Control (BCCCDC) the near field zone is referred to as chaotic. In his zone both Industry Canada (IC) and the BCCDC specify both the Electric Field and Magnetic Fields must be measured in several locations to obtain the true power density readings.

The extent of the danger zones around an emitting device is determined by a series of calculations based on the frequency (wavelength) and size of the antenna. Additional confusions can be introduced by interference from other sources, reflected energy, stored energy and antenna design and imperfections to name a few of the other sources of complexity that may possibly exist.

The Danger zone around a cell phone can be consider to be in the order of 0.1 m and greater if the phone is using wifi. A cell phone antenna – even ones on roof tops over 12 meters to the extreme danger limit and 50 meters to the high danger zone. Larger antennas or higher frequencies could extend these distances considerably. A home wifi router the minimum distance to the extremely dangerous zone limit 0.1 and to the highly dangerous zone 0.3 meters (1 ft). For a laptop assume distance in excess of 1 meter and 4 meters respectively.

Vast Majority of Consumers Suffer Financial “Net Loss” with Smart Meters

Robert Daniel 9 years ago 0

Image 11This article provides specific information to counter claims made by smart meter proponents that smart meters provide consumers with financial benefits, i.e., saving energy and reducing their utility bill. In addition, this article presents information to help disentangle how policy makers conflate the topics of grid modernization, smart meter deployments, and sound environmental policy.


Inflated or False Claims on How Smart Meters Help Consumers Save Money

As an attempt to convince consumers that smart meters are “good” for them, they are fed propaganda-like messages regarding “consumer empowerment” by smart meter proponents. In short, and as stated by the Attorney General for the state of Illinois:

“The pitch is that smart meters will allow consumers to monitor their electrical usage, helping them to reduce consumption and save money. … Consumers don’t need to be forced to pay billions for so-called smart technology to know how to reduce their utility bills. We know to turn down the heat or air conditioning and shut off the lights.”

Internet by light promises to leave Wi-Fi eating dust

Robert Daniel 9 years ago updated by Shaun Kranish 9 years ago 0

Image 9Barcelona (AFP) - Connecting your smartphone to the web with just a lamp -- that is the promise of Li-Fi, featuring Internet access 100 times faster than Wi-Fi with revolutionary wireless technology.

French start-up Oledcomm demonstrated the technology at the Mobile World Congress, the world's biggest mobile fair, in Barcelona. As soon as a smartphone was placed under an office lamp, it started playing a video.

The big advantage of Li-Fi, short for "light fidelity", is its lightning speed.

Laboratory tests have shown theoretical speeds of over 200 Gbps -- fast enough to "download the equivalent of 23 DVDs in one second", the founder and head of Oledcomm, Suat Topsu, told AFP.

"Li-Fi allows speeds that are 100 times faster than Wi-Fi" which uses radio waves to transmit data, he added.

The technology uses the frequencies generated by LED bulbs -- which flicker on and off imperceptibly thousands of times a second -- to beam information through the air, leading it to be dubbed the "digital equivalent of Morse Code".

It started making its way out of laboratories in 2015 to be tested in everyday settings in France, a Li-Fi pioneer, such as a museums and shopping malls. It has also seen test runs in Belgium, Estonia and India.

Dutch medical equipment and lighting group Philips is reportedly interested in the technology and Apple may integrate it in its next smartphone, the iPhone7, due out at the end of the year, according to tech media.

With analysts predicting the number of objects that are connected to the Internet soaring to 50 million by 2020 and the spectrum for radio waves used by Wi-Fi in short supply, Li-Fi offers a viable alternative, according to its promoters.

"We are going to connect our coffee machine, our washing machine, our tooth brush. But you can't have more than ten objects connected in Bluetooth or Wi-Fi without interference," said Topsu.

Deepak Solanki, the founder and chief executive of Estonian firm Velmenni which tested Li-fi in an industrial space last year, told AFP he expected that "two years down the line the technology can be commercialised and people can see its use at different levels."

Analysts said it was still hard to say if Li-Fi will become the new Wi-Fi.

"It is still a laboratory technology," said Frederic Sarrat, an analyst and consultancy firm PwC.

Much will depend on how Wi-Fi evolves in the coming years, said Gartner chief analyst Jim Tully.

"Wi-Fi has shown a capability to continuously increase its communication speed with each successive generation of the technology," he told AFP.

Li-fi has its drawbacks -- it only works if a smartphone or other device is placed directly in the light and it cannot travel through walls.

This restricts its use to smaller spaces, but Tully said this could limit the risk of data theft.

"Unlike Wi-Fi, Li-Fi can potentially be directed and beamed at a particular user in order to enhance the privacy of transmissions," he said.

Backers of Li-Fi say it would also be ideal in places where Wi-Fi is restricted to some areas such as schools and hospitals.

"Li-fi has a place in hospitals because it does not create interference with medical materials," said Joel Denimal, head of French lighting manufacturer Coolight.

In supermarkets it could be used to give information about a product, or in museums about a painting, by using lamps placed nearby.

It could also be useful on aircraft, in underground garages and any place where lack of Internet connection is an issue.

But Li-Fi also requires that devices be equipped with additional technology such as a card reader, or dongle, to function. This gives it a "cost disadvantage", said Tully.

Mobile phones are 'cooking' men's sperm

Fertility experts are warning man that using a mobile for as little as an hour a day is "cooking sperm" and lowering level significantly.

The new study shows that having a mobile phone close to the testicles - or within a foot or two of the body - can lower sperm levels so much that conceiving could be difficult.

The findings have led to a leading British fertility expert to advise men to stop being addicted to mobile phones.

"If you wear a suit to work put the mobile in your chest pocket instead of close to your testes. It will reduce the risk of your sperm count dropping or dropping so much."
- Prof Gedis Grudzinskas

The study - by highly respected specialists - found that sperm levels of men who kept their phones in their pocket during the day were seriously affected in 47 per cent of cases compare to just 11 per cent in the general population.

Professor Martha Dirnfeld, of the Technion University in Haifa, said: "We analysed the amount of active swimming sperm and the quality and found that it had been reduced.

"We think this is being caused by a heating of the sperm from the phone and by electromagnetic activity." [emphasis added by IEHA. Notice the scientist says heating of the sperm (thermal effects) but then he says AND electromagnetic activity (NON-thermal effects). This scientist knows and is confirming that there are non-thermal effects of EMF exposure.

The team monitored more than 100 men attending a fertility clinic for a year.

They found that besides men keeping their phones close to their groin many spoke on the phone while it was charging and kept it only a few centimeters from their bed.

Even keeping the phone on a bedside table appears to raise lower sperm cell counts.
The findings are in the journal Reproductive BioMedicine and support a long-feared link between dropping fertility rates in men and the prevalent use of cellular phones.

The quality of sperm among men in Western countries is constantly decreasing and is considered crucial in 40 percent of the cases in which couples have difficulty conceiving a child.

Professor Gedis Grudzinskas, a fertility consult ant St George's Hospital London and in Harley Street said: " Men need to think about their well being and try to stop being addicted to their phones.

"If you wear a suit to work put the mobile in your chest pocket instead of close to your testes. It will reduce the risk of your sperm count dropping or dropping so much.

"Women generally don't carry their mobiles on them so maybe a mobile phone won't affect their fertility. That's not something we have looked at"
- Prof Martha Dirnfeld

"And do you need to keep the phone right next to you on the bedside table. Some men keep their mobile in their shorts or pajamas in bed. Is that really necessary?"

Professor Dirnfeld said: "I think this is a warning to men to change their habits to improve their chances of having children. Women generally don't carry their mobiles on them so maybe a mobile phone won't affect their fertility. That's not something we have looked at."

Professor Alan Pacey, a fertility research scientist at Sheffield University has scoffed at suggestions that mobile phones could be damaging male fertility and insists he will be carry on putting his mobile in his trouser pocket.

Professor Dirnfeld said: "Dr Pacey might not need to worry about his fertility, but for younger guys it is a worry. If you a trying for a baby and it doesn't happen within a year you might want to think of whether it could be your mobile phone habit that is to blame."


Severe Bluetooth reaction in Buick Enclave

Shaun Kranish 9 years ago updated by Angie@W 4 years ago 4

I just wanted to share a personal experience from this past weekend. I am sensitive, yes, but I don't normally react so badly that I notice it immediately. My EMF sensitivity is more of a dragging my health down sort of thing. But once in a great while I will have a severe reaction and notice it.


So this past weekend was one of those. I was riding with family in a Buick Enclave. I was in the back seat. Within a minute or two of getting into the car I felt sick - really bad waves of nausea - feeling flush on my face - and overall just feeling really really sick. We arrived at our destination shortly after, and then I felt fine again. In fact I forgot about it.


When we left and I got into the car, the same exact reaction occurred. Unfortunately in this car the Bluetooth cannot be disabled. I won't be riding in there anymore until that dashboard is taken apart and it's manually/physically disabled. What a terrible feeling it was!!!

Theory on How Weak Magnetic Fields Can Promote Cancer

Robert Daniel 9 years ago updated 9 years ago 0

Image 22Weak RF fields may indeed be able to promote cancer, according to two leading members of the EMF/RF research community. Frank Barnes and Ben Greenebaum are offering theoretical arguments to explain how low-level RF radiation can alter the growth rates of cancer cells. They present their ideas in an article which has just appeared in the IEEE Power Electronics Magazine.


“Stuff is going on,” Barnes told Microwave News. “We can see changes with very small fields.” He granted that some may interpret what he is saying as “heresy.”

“What we are postulating does not violate any laws of physics and chemistry,” said Barnes, a distinguished professor emeritus of electrical engineering at the University of Colorado in Boulder and a long-time member of the National Academy of Engineering. Greenebaum, a professor emeritus of physics at University of Wisconsin-Parkside, was the editor-in-chief of BIoelectromagnetics from 1993 to 2006. Barnes and Greenebaum are coeditors of the most recent edition of the CRC Handbook of Biological Effects of Electromagnetic Fields.

“Bob Adair’s calculations are not wrong,” Barnes added. “They just don’t deal with the situations we are dealing with.” He was referring to Robert Adair, a professor emeritus of physics at Yale University, who has long maintained that weak field effects are incompatible with the laws of physics (more on Adair). Barnes was careful to point out that not all experiments would show effects because “biological systems have many feedback and repair mechanisms.”

“We have a reasonable hypothesis with a framework which allows others to do experiments which can show whether we are right or wrong,” Barnes said.

Illinois Attorney General Issues Consumer Alert on ‘Smart’ Meters

Robert Daniel 9 years ago 0

Image 20Illinois Attorney General Lisa Madigan today issued a consumer alert “urging Illinois residents to do their homework on smart meters – how they work, what type of data they collect, how the data can be used and if you authorize it, who can access it.” [1]


In an interview with WLS-TV of Chicago, Lisa Madigan said that:

There is a “lot of potential for consumers to be deceived.”

“There’s a possibility that [energy suppliers] will also be able to determine whether or not people are in the home. There are some people that may not feel comfortable with sharing that information.” [2]

Questions Remain Unanswered Regarding Potential Health Effects Related to Smart Grid Technologies

Robert Daniel 9 years ago 0

Image 19In June and July of 2011, the Electric Power Research Institute (EPRI) hosted two separate workshops related to the possible health effects associated with radiofrequency (RF) emissions from smart grid technologies. In December 2011, EPRI published a report summarizing the results and findings from those workshops [1].


The first workshop on “technology” identified numerous electromagnetic field (EMF) emission sources from smart grid-related components that might cause health effects. Supposedly, EPRI would follow-up and study these possible sources and “inform the public about emissions associated with emerging smart grid technologies.” I conclude that this informing of the public has not yet happened.

A second workshop on “health effects” reviewed the science available in 2011 regarding EMF-related health effects and identified “critical gaps and research needs” for smart grid technologies. Regarding this workshop, I am not aware of progress being made in completing the identified research other than periodic field testing of wireless smart meters to ensure that emission rates comply with outdated Federal exposure guidelines.

After reviewing the summary information from the EPRI workshops in 2011, I am left with two impressions that are quite disturbing:

  • With the health issues that exist related to smart grid technologies, how could the smart grid industry continue to move forward with deployments even though there are acknowledged “critical gaps and research needs”?
  • In many instances, members of the public are mocked as subscribing to conspiracy theories when expressing health concerns over smart meters. How can smart grid industry officials and proponents so readily dismiss public concerns and health complaints based upon the science summarized in the EPRI report that would tend to substantiate those concerns and complaints as well-founded and legitimate?

TEDx Talk: Wireless Wake-Up Call

Robert Daniel 9 years ago 0

On February 6th, [Jeromy Johnson] had the opportunity to speak at TEDxBerkeley. The title of my talk was “Wireless Wake-Up Call.” I discussed the health effects related to the explosion in wireless technology the past few years, along with solutions that can help everyone. Within the presentation, I also talked about how we can develop technology that is much safer for humanity. Here is the video:


Youtube video

Zellerbach Hall on the UC Berkeley campus is an incredible venue. It seats 2,000 people and this event was sold-out. I was the second speaker of the day and the first couple minutes on stage were a bit nerve-racking. As you will see in my opening questions, there was an uncomfortable moment for everyone (it felt like the entire room needed to pause). It happened when I asked who knew that the fine print in every smart phone owner’s manual says to never put the phone within about 1 inch of the body. This is a truth that is currently taboo to discuss in our society, so few people know about it. However, once we got through this moment, the talk soon became fun and was well-received by many in the audience.


In my talk, I wanted to convey that people are indeed being harmed by this technology and that there is adequate science to show how and why this is happening. Most importantly though, I provided solutions that every family can utilize today to reduce their exposure and encouraged us all to help society wake-up. Once this happens, our technology industries will create safe products that will move our entire society toward a healthier future.

The Smart Dryer and Time-Of-Use Rates

Robert Daniel 9 years ago 0

Image 15Within the last couple of months I have posted comprehensive articles to demonstrate how consumers financially suffer with smart meters and that they are also financially and socially punished when subjected to Time-of-Use (TOU) electricity rates [1] [2].


Those articles, although comprehensive, were somewhat broad in nature. Let us take a closer look at one particular household appliance that is frequently touted by smart grid proponents, the “smart” dryer. It is advertised that you can “save money” by using a smart tumble dryer in the late evening when electricity rates are low. There is an inference that you would place your washed clothing in a smart dryer, go to bed, and the dryer would later turn on and complete its drying cycles while you were sleeping. Before proceeding, let me present some common sense public service advice on tumble dryer safety:

Tumble Dryer Safety: “Occupants are advised to use tumble dryers and washing machines when they can be supervised. Ideally they should not be switched on and left to run overnight whilst people are sleeping. We would encourage people to switch off all electrical appliances when vacating the house and during the night to reduce the risk of fire in the home.”

How close is too close to a cell tower?

Shaun Kranish 9 years ago updated by nnxr 8 years ago 2

My parents are looking at property outside of the city - they are thinking to retire a little ways out into the country.


My wife and I went with them to look at this one property - and it's very, very nice. Lots of acreage, a large springfed lake right on the property (the water was crystal clear, lots of nice big fish in it as well). Log cabin style home, lots of space, gosh what a nice property.


Knowing me I did an antennasearch.com search before even going out there and there's a big tower smack dab across the street. Luckily it's a long driveway, but the tower is still about 2600 feet from the house.


We went out there to look at the property and geez the tower is big. BIG tower with tons of antennas on it. Readings in front of the house were 100 microwatts/m2 or greater. Inside the house wasn't as bad - the house does a decent job of blocking. I'm going to take more measurements and actually use the frequency filters this time - but it was raining when I was out there last so I couldn't take many measurements outside.


So, what does everyone think? A BIG cell tower staring at you a half mile away - line of sight - no trees or anything in between. Ugh this property would be so ideal if it weren't for that. Would love to hear what others think.
