Flickering is the opposing changes in intensity of luminosity. This is usually caused by flashing, but can also be caused by spatial contrast patterns that oscillate at dangerous frequencies; the type of images that people create to deliberately stimulate a response in the recipient that makes them believe the image is moving or changing. For people with photosensitive epilepsy, flickering causes many of the nerve cells that process visual stimuli to all fire at once, resulting in a seizure”

“Along with the frequency of the flickering, the size and luminous intensity of the stimuli is significant for people with photosensitive epilepsy. The greater the intensity and larger the size of the stimuli, the greater the danger of provoking seizures caused by flickering at dangerous frequencies.”

“The colour red is particularly dangerous due to its longer wavelength that stimulates cones in the retina. There have been cases where photosensitive epileptic seizures have been triggered by cyclists while setting up the red flashing rear lights on their bicycle. Even when there is no perceived difference in the luminosity of the contrasting colours, red flickering is far more likely to cause seizures than other colours.”
“Television programmes are thought to be the most common cause for triggering photosensitive epileptic seizures. The most famous incident of photosensitive epilepsy caused by a television programme is the Pokémon episode, Electronic Soldier Porygon , which was aired in Japan in 1997. Nearly 700 children were admitted to hospital through photosensitive epilepsy that was thought to have been induced by the episode.”

People with photosensitive epilepsy can have seizures triggered by flickering or flashing in the 4 to 59 flashes per second (Hertz) range with a peak sensitivity at 20 flashes per second as well as quick changes from dark to light (like strobe lights).When content violates either the general flash threshold or the red flash threshold , users are warned in a way that they can avoid it

Content does not violate the general flash threshold or red flash threshold

“Allowing people to choose whether or not they receive the content is better than not providing a warning, but there are other factors to consider. The first is that as photosensitive epilepsy is most common in children, it could be that they don’t understand or appreciate the significance of the warning. It isn’t just children; people with reading difficulties or speakers of languages other than the language of the warning may also inadvertently be exposed to content that could induce seizures.”

“Although the size of the stimuli is significant, there is still a danger of material that is considered to be safe being changed by the visitor. For example, low vision users increasing the size of flickering material, or someone leaning in close to the screen.”

“The safest way to avoid causing photosensitive epilepsy is to completely avoid creating web content that flickers.”

“People with photosensitive epilepsy who suddenly find themselves exposed to material that could trigger a seizure should immediately cover one eye with the palm of their hand to reduce the number of brain cells that are stimulated by the flickering content, and either close the page or navigate away from the page.”

“Photosensitive epilepsy is a form of epilepsy that is triggered by visual stimuli, such as flickering or high contrast oscillating patterns, and it’s believed that around 3% to 5% of people with epilepsy are susceptible to photosensitive material. Photosensitive epilepsy is usually triggered where the flicker rate is between 16Hz to 25Hz, although it’s not uncommon for seizures to be triggered by flicker rates between 3Hz to 60Hz. The condition most commonly effects children, and is usually developed between the ages of 9 and 15 years, and most prevalent in females.”

Electric appliances in the household
The strongest power frequency electric fields that are ordinarily encountered in the environment exist beneath high voltage transmission lines. In contrast, the strongest magnetic fields at power frequency are normally found very close to motors and other electrical appliances, as well as in specialized equipment such as magnetic resonance scanners used for medical imaging.

(Typical electric field strengths measured near household appliances
(at a distance of 30 cm)
(From: Federal Office for Radiation Safety, Germany 1999)

Electric appliance Electric field strength (V/m)
Stereo receiver 180
Iron 120
Refrigerator 120
Mixer 100
Toaster 80
Hair dryer 80
Colour TV 60
Coffee machine 60
Vacuum cleaner 50
Electric oven 8
Light bulb 5
Guideline limit value 5000

Many people are surprised when they become aware of the variety of magnetic field levels found near various appliances. The field strength does not depend on how large, complex, powerful or noisy the device is. Furthermore, even between apparently similar devices, the strength of the magnetic field may vary a lot. For example, while some hair dryers are surrounded by a very strong field, others hardly produce any magnetic field at all. These differences in magnetic field strength are related to product design. The following table shows typical values for a number of electrical devices commonly found in homes and workplaces. The measurements were taken in Germany and all of the appliances operate on electricity at a frequency of 50 Hz. It should be noted that the actual exposure levels vary considerably depending on the model of appliance and distance from it.

“According to Dr. Robert O. Becker in his book “The Body Electric,” the human body has an electrical frequency and that much about a person’s health can be determined by it. Frequency is the measurable rate of electrical energy flow that is constant between any two points. Everything has frequency.”

“Dr. Royal R. Rife found that every disease has a frequency. He has found that certain frequencies can prevent the development of disease and that others would destroy diseases. Substances of higher frequency will destroy diseases of lower frequency.”

“In 1992, Bruce Taino of Taino Technology, an independent division of Eastern State University in Cheny, Washington, built the first frequency monitor in the world. Taino has determined that the average frequency of a healthy human body during the daytime is 62 to 68 Hz. When the frequency drops, the immune system is compromised. If the frequency drops to 58 Hz, cold and flu symptoms appear; at 55 Hz, diseases like Candida take hold; at 52 Hz, Epstein Bar and at 42 Hz, Cancer. Taino’s machine was certified as 100 percent accurate and is currently being used in the agricultural field today.”

“The study of frequencies raises an important question concerning the frequencies of substances we eat, breathe, and absorb. Many pollutants have low frequencies and cause the bodies healthy frequencies to be lowered and weakened. Processed or canned food has a frequency of zero and tend to lower healthy frequencies within the body towards degenerative diseases. Fresh produce has up to 15 Hz; dry herbs from 12 to 22 Hz; and fresh herbs from 20 to 27 Hz. Essential oil frequencies start at 52 Hz and go as high as 320 Hz; which is the frequency of Rose Oil. These higher frequencies create an environment in which disease, bacteria, virus, fungus, cancer, etc., CANNOT live.”…..“In one study the doctors took two young men who had a 66-hertz frequency. One held coffee and his frequency dropped to 58 in 3 seconds. The other gentleman drank it and his frequency dropped to 52 in 3 seconds.”

What is Magnetic Radiation? September 9, 2006

“Every (electric) current going through a wire generates magnetic radiation which travels around the wire. There is continuing controversy regarding possible health effects of exposure to this radiation. The U.S. Environmental Protection Agency (EPA) and the U.S. Navy performed a study which reported that 5 out of 6 laboratories found increased levels of embryological changes in chickens when exposed to magnetic radiation. Other tests have shown biological effects on mice, miniature pigs, and humans. Recent articles claim or at least suspect that exposure to high levels of ELF radiation is a factor in leukemia in children….

“Magnetic radiation surveys measure Extremely Low Frequency (ELF) and Very Low Frequency (VLF) fields which have nothing to do with high frequency radioactivity such as radon, X-rays, and so-called ionizing radiation… Magnetic radiation is produced by high tension power lines, but also by ordinary secondary lines, power transformers, household wiring, certain electric radiant heating devices, improperly grounded appliances.”

“EMF” is an acronym for Electromagnetic Frequency 

“On a daily basis, most …are exposed to EMFs generated by household wiring, fluorescent lighting, and any electrical appliance that plugs into the wall, including hair dryers, vacuum cleaners and toasters. In the workplace, common sources include video display terminals (computer monitors), air purifiers, photocopiers, fax machines, fluorescent lights, electric heaters and electric tools in machine shops, such as drills, power saws, lathes and welding machines.”

Electromagnetic fields Photos permitted by the National Radiological Protection Board, UK

“Electromagnetic fields of all frequencies represent one of the most common and fastest growing environmental influences, about which anxiety and speculation are spreading. All populations are now exposed to varying degrees of EMF, and the levels will continue to increase as technology advances.”

“As part of its Charter to protect public health and in response to public concern, the World Health Organization (WHO) established the International EMF Project in 1996 to assess the scientific evidence of possible health effects of EMF in the frequency range from 0 to 300 GHz.”
“The EMF Project is open to broad participation.”

“The EMF Project is open to any WHO Member State government, i.e. department of health, or representatives of other national institutions concerned with radiation protection. The project is fully funded by participating countries and agencies.”

Effects of 50 Hz EMF exposure on micronucleus formation and apoptosis in transformed and nontransformed human cell lines.

Simko M, Kriehuber R, Weiss DG, Luben RA.

Institute of Animal Physiology, Unit of Environmental Physiology, University of Rostock, Germany. myrtill.simko@biologie.uni-rostock.de

“Effects of applying extremely low-frequency electromagnetic fields (ELF-EMF) for different durations (24, 48, and 72 h) and different field intensities (0.1-1.0 mT) on micronucleus (MN) formation and induction of apoptosis were examined in a human squamous cell carcinoma cell line (SCL II) and in a human amniotic fluid cell line (AFC). A statistically significant increase of MN frequency and of induction of apoptosis in SCL II cells after 48-h and 72-h continuous exposure to 50 Hz magnetic field (MF) (0.8 and 1.0 mT) was found. However, exposure of AFC cells to EMF of different intensities and for different exposure times showed no statistically significant differences when compared with controls. These results demonstrate that different human cell types respond differently to EMF. Dose-dependent induction of apoptosis and genotoxic effects, resulting in increased micronucleus formation, could be demonstrated in the transformed cell line, whereas the nontransformed cell line did not show statistically significant effects. These findings suggest that EMF could be a promotor but not an initiator of carcinogenic effects.”

“A 60-Hz magnetic field increases the incidence of squamous cell carcinomas in mice previously exposed to chemical carcinogens.

by McLean J, Thansandote A, Lecuyer D, Goddard M, Tryphonas L, Scaiano JC, Johnson F
published in: Cancer Lett 1995; 92 (2): 121 – 125″

Aim of study

“To investigate the effects of a 60 Hz magnetic field exposure on skin tumor development in the SENCAR-mouse-model.
Background/further details:

DMBA and PMA were used to initiate and promote cancer development. A total of 96 mice were used in this study (2 groups/48 animals each). One group was magnetic field exposed, whereas the other was sham exposed. Each mouse obtained a single, sub-carcinogenic DMBA administration (10 nmol). One week thereafter the weekly administration of PMA (0.3 µg) began and were conducted over the next 23 weeks. Magnetic field exposure and sham exposure were conducted for additional 29 weeks (total exposure/sham exposure time 52 weeks)….”

Main outcome of study

“The number of tumor-bearing mice was not significantly altered after 52 weeks. However, the number of squamous cell carcinomas in the magnetic field exposed group was statistically significant increased.”

“The most basic fact about cell phones and cell towers is that they emit microwave radiation; so do Wi-Fi (wireless Internet) antennas, wireless computers, cordless (portable) phones and their base units, and all other wireless devices. If it’s a communication device and it’s not attached to the wall by a wire, it’s emitting radiation. Most Wi-Fi systems and some cordless phones operate at the exact same frequency as a microwave oven, while other devices use a different frequency. Wi-Fi is always on and always radiating. The base units of most cordless phones are always radiating, even when no one is using the phone. A cell phone that is on but not in use is also radiating. And, needless to say, cell towers are always radiating.”The Largest Biological Experiment Ever ARTHUR FIRSTENBERG / Sun Monthly 1jan2006

“Why is this a problem, you might ask? Scientists usually divide the electromagnetic spectrum into “ionizing” and “non-ionizing.” Ionizing radiation, which includes x-rays and atomic radiation, causes cancer. Non-ionizing radiation, which includes microwave radiation, is supposed to be safe. This distinction always reminded me of the propaganda in George Orwell’s Animal Farm: “Four legs good, two legs bad.” “Non-ionizing good, ionizing bad” is as little to be trusted.”

“An astronomer once quipped that if Neil Armstrong had taken a cell phone to the Moon in 1969, it would have appeared to be the third most powerful source of microwave radiation in the universe, next only to the Sun and the Milky Way. He was right. Life evolved with negligible levels of microwave radiation. An increasing number of scientists speculate that our own cells, in fact, use the microwave spectrum to communicate with one another, like children whispering in the dark, and that cell phones, like jackhammers, interfere with their signaling. In any case, it is a fact that we are all being bombarded, day in and day out, whether we use a cell phone or not, by an amount of microwave radiation that is some ten million times as strong as the average natural background. And it is also a fact that most of this radiation is due to technology that has been developed since the 1970s.”
