In the current study, the pattern of the response of E coli to Wi-Fi and RF simulator radiation was identical. The maximum differences in the diameters of inhibition zones were observed between 6 and 9 hours of the bacterial exposure to radiation (Figures 1 and 2). After 12 hours of exposure, the bacterial responses to radiation as a stressor led to returning to the preexposure status.
And yet, a lot of people do use these, including people I know and respect. I see people on the subway playing Candy Crush, the cover of their folio-style wallet case folded back, all of their cards just flapping in the wind. And don’t just take my word for it: The Silk iPhone wallet case has nearly 2,000 reviews on Amazon with an average score of 4.5 stars. People not only use these cases—they love them!
The HARApad laptop pad is available in 3 sizes and multiple colors. There's even an attractive wood option, which allows for a beautiful, natural approach to laptop radiation shielding. There are size options for 13″, 15″ and 17″ laptops, and even a 25″ LapDesk version that will allow for the convenient use of a mouse, if you use a mouse instead of a trackpad.
33. Avoid Electro Hypersensitivity (EHS) due to the location of an Electromotive Force (EMF) source. “Don’t wear metal-rimmed glasses when using a cell phone,” advises the Center for Safer Wireless. Additionally, the Center for Safer Wireless suggests that you should “refrain from using your cell phone in a car, bus or train. Metal reflects wireless radiation, and it bounces around you when on a cell phone in this environment.”– Cell Phone Safety Tips, Center for Safer Wireless; Twitter: @SaferEMF
As with exposure to ‘anything’ sun, pollen, pharmaceuticals, there will be a certain percent of population that is ‘sensitive or hypersensitive’ to wifi / emf frequency. I am definitely sensitive with my husband doing his own control experiment by holding his wifi phone behind by head without my knowledge and me In pain from a piercing wave going through my head. Why is it that it must be all or nothing. There are those who will never be sick from wifi/ emf and those of us who live with it everyday.

Anything you can do to keep the phone away from your head will help. (Even cell phone manufacturers warn consumers about this. See the previous post Cell Phone Manual Warnings for examples of warnings from Samsung, Apple and more.) If you hold the phone 2 inches away, the signal is about one-fourth the original strength. At four inches away, it’s about 1/16th as strong. Even better is a hands-free kit with a wireless air tube nearest the earpiece. (A regular wired headset can act as an antenna and make matters worse.)


The present work investigated the effects of prenatal exposure to radiofrequency waves of conventional WiFi devices on postnatal development and behavior of rat offspring. Ten Wistar albino pregnant rats were randomly assigned to two groups (n=5). The experimental group was exposed to a 2.45GHz WiFi signal for 2h a day throughout gestation period. Control females were subjected to the same conditions as treated group without applying WiFi radiations. After delivery, the offspring was tested for physical and neurodevelopment during its 17 postnatal days (PND), then for anxiety (PND 28) and motricity (PND 40-43), as well as for cerebral oxidative stress response and cholinesterase activity in brain and serum (PND 28 and 43). Our main results showed that the in-utero WiFi exposure impaired offspring neurodevelopment during the first seventeen postnatal days without altering emotional and motor behavior at adult age. Besides, prenatal WiFi exposure induced cerebral oxidative stress imbalance (increase in malondialdehyde level (MDA) and hydrogen peroxide (H2O2) levels and decrease in catalase (CAT) and superoxide dismutase (SOD) activities) at 28 but not 43days old, also the exposure affected acethylcolinesterase activity at both cerebral and seric levels. Thus, the current study revealed that maternal exposure to WiFi radiofrequencies led to various adverse neurological effects in the offspring by affecting neurodevelopment, cerebral stress equilibrium and cholinesterase activity.
Cell phone cases can make matters worse because they may block the phone’s antenna. The device must work harder to transmit signals which may lead to  more radiation exposure for the user. (See safety tip #6 for more on the importance of a strong signal.)  Certification testing done by phone manufacturers are done with bare phones with no accessories.

Joel Moskowitz (@berkeleyprc) of the University of California, Berkeley School of Public Health, US, says: “This is the largest technological experiment in the history of our species, with potential health risks we still know next to nothing about.” This view is shared by Denis Henshaw, professor of human radiation effects at Bristol University, UK, who said: “Vast numbers of people are using cell phones and this could be a time bomb of health problems.”
