Based on our results, it can be concluded that the bacterial strains used in this study respond differently to EMFs. These bacteria were capable of responding to environmental stresses that act by activating some specific systems such as ion channels, change via the membrane, DNA repair system, and probably ion efflux pumps in the membrane as well as interactions of molecules and antibacterial agents.  There are some ambiguities that need further investigations regarding answering questions such as which cellular mechanism is responsible for adaptation? Which factors are involved in alterations of antibacterial sensitivity? And subsequently, what are the differences in the response to radiation in gram-negative and gram-positive bacteria? Moreover, experiments on different bacterial strains with various electromagnetic fields should be performed in the future to better clarify these uncertainties.
The cell phone pocket shield allows you to use your earbuds or headphones during a call but at the same time, safely place your cell phone in your pocket, purse, etc. This means you are protected both when the phone is connected on a call or sitting idle. The shield will not interfere with your cellular signal and will not negatively affect battery life.
Thanks to the massive selection of cell phone cases and covers on eBay, it's never been easier to find the accessories that are perfect for you and your lifestyle. Choose from brand new premium brands, such as Spigen and Incipio, that make a bold statement every time you answer a call; or pick out something functional and understated from the inventory of budget options for cost-conscious buyers, such as items from Speck. It's even possible to find cases for older phones that you cannot get in stores. With a case for every phone and every budget, you are able to purchase with confidence, knowing you are making the right call for protecting your phone.
In certain situations, it's necessary to use your cell phone when your hands are otherwise occupied. For those times, a Bluetooth headset comes in handy. These lightweight headsets attach above one or both of your ears or around your neck, and allow you to talk without having to do so directly into your phone. These are rechargeable devices that offer around eight hours of talk time. You can also listen to music and use GPS applications and many other apps that your phone has. Bluetooth headsets are compatible with most or all Bluetooth-enabled mobile devices.
These studies are not definitive. Much more research is needed. But they raise serious questions that cast doubt on the adequacy of the FCC rules to safeguard public health. The FCC emissions cap allows 20 times more radiation to reach the head than the body as a whole, does not account for risks to children’s developing brains and smaller bodies and considers only short-term cell phone use, not frequent calling patterns over decades.
Even so, the industry’s neutralizing of the safety issue has opened the door to the biggest, most hazardous prize of all: the proposed revolutionary transformation of society dubbed the “Internet of Things.” Lauded as a gigantic engine of economic growth, the Internet of Things will not only connect people through their smartphones and computers but will connect those devices to a customer’s vehicles and home appliances, even their baby’s diapers—all at speeds faster than can currently be achieved.25

Some implanted medical devices use radio frequency communication - both to report status, and to allow changing device behavior. Emissions from wireless electronic devices can interfere with the functioning of these devices, thereby adversely affecting the health of the user. Users of such implanted devices are usually cautioned to avoid close exposure to other wireless devices.

Since the development of communication devices and expansion of their applications, there have been concerns about their harmful health effects. The main aim of this study was to investigate laptop thermal effects caused by exposure to electromagnetic fields and thermal sources simultaneously; propose a nondestructive, replicable process that is less expensive than clinical measurements; and to study the effects of positioning any new device near the human body in steady state conditions to ensure safety by U.S. and European standard thresholds. A computer simulation was designed to obtain laptop heat flux from SolidWorks flow simulation. Increase in body temperature due to heat flux was calculated, and antenna radiation was calculated using Computer Simulation Technology (CST) Microwave Studio software. Steady state temperature and specific absorption rate (SAR) distribution in user's body, and heat flux beneath the laptop, were obtained from simulations. The laptop in its high performance mode caused 420 (W/m2 ) peak two-dimensional heat flux beneath it. The cumulative effect of laptop in high performance mode and 1 W antenna radiation resulted in temperatures of 42.9, 38.1, and 37.2 °C in lap skin, scrotum, and testis, that is, 5.6, 2.1, and 1.4 °C increase in temperature, respectively. Also, 1 W antenna radiation caused 0.37 × 10-3 and 0.13 × 10-1.


There was a negative correlation between the cell phone usage duration and the total sperm count (r = −0.064, p = 0.04). Similarly, there was also a negative correlation between the wireless internet usage duration and the total sperm count (r = −0.089, p = 0.019). Otherwise there were no significant correlations among the other four main question branches (cell phone usage time, cell phone carriage habits, wireless internet usage time. and internet connection type) and sperm parameters.
This study was an in-vitro pilot study which established the effect of radiofrequency radiation from 2.4 GHz laptop antenna on human semen. A test of significance between results of semen parameters using Mann-Whitney U- test at 0.05 level of significance showed a significant effect of RFR exposure on  sperm concentration, motility and morphology grading.
Because of this physical law, even if  holding a Wi-Fi router directly against your forehead was very dangerous (and, we assure you, it is not) working in your home office 45 feet away from the Wi-Fi router would not be dangerous simply because the microwave radiation of the already minuscule 1 watt Wi-Fi router would have radically decreased in intensity. When you factor in that the Wi-Fi radiation is already harmless, you see that there is no situation in which the Wi-Fi signal from your router, your laptop, your media center, or any other Wi-Fi device in your home could possibly hurt you.

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.)

37. Be careful when sharing your phone number. Teenagers may be so excited to finally have their own cell phone or smartphone that they immediately give out their number to everyone they know – or worse, publish it online on their social media profiles. “Only give out your phone number to people you know for sure you can trust.” – Sameer Hinduja, Ph.D. and Justin W.

Who can master dropping their phone down that tiny slit that exists when the elevator doors open? This girl! My iPhone 5s SURVIVED an eight story plummet down the elevator shaft at work thanks to my Commuter Series case!!! I thought for sure the screen would be cracked and the phone would be in a million pieces, but the screen wasn’t cracked or even scratched for that matter and it fully functions! The case took a little beating and there is a dent on the phone, but that’s nothing compared to the alternative! Thanks for making such a great product!!!! And to think, I was just complaining that I wanted something less bulky!!!

The energy of electromagnetic radiation is determined by its frequency; ionizing radiation is high frequency, and therefore high energy, whereas non-ionizing radiation is low frequency, and therefore low energy. The NCI fact sheet Electromagnetic Fields and Cancer lists sources of radiofrequency radiation. More information about ionizing radiation can be found on the Radiation page.


This study was aimed at investigating the alteration of antibiotic resistance of Klebsiella pneumonia, after exposure to Wi-Fi 2.4 GHz electromagnetic radiofrequency radiation from a Wi-Fi router for 3, 4.5 or 8 hours. The findings of this study show a statistically significant rise in the sensitivity of Klebsiella pneumoniae to different antibiotics after 4.5 hours of exposure to 2.4 GHz Wi-Fi radiation, followed by a fall after 8 hours of exposure. These observations can be interpreted by the concept of non-linearity in the responses of Klebsiella pneumoniae to different antibiotics after exposure to electromagnetic radiofrequency radiation.
These experimental findings raise new questions as to the potential for radiofrequency radiation to result in cellular changes and offer potential avenues for further laboratory studies. Cancers in the heart are extremely rare in humans, where the primary outcomes of potential concern with respect to radiofrequency radiation exposure from cell phones are tumors in the brain and central nervous system. Schwann cells of the heart in rodents are similar to the kind of cells in humans that give rise to acoustic neuromas (also known as vestibular schwannomas), which some studies have suggested are increased in people who reported the heaviest use of cell phones. The NTP has stated that they will continue to study this exposure in animal models to further advance our understanding of the biological underpinnings of the effects reported above.

If you are concerned about the possible health effects of radio wave radiation emitted by your cell phone, your options are simple and cheap. This kind of radiation is at its highest levels nearest the antenna. Also, not all cell phones are created equal. Sar Shield offers a useful radiation chart for cell phones that provides an accurate "Sar rating" for every cell phone model. It's important to realize that at these low radiation levels, if you keep the cell phone away from your head and body, you are perfectly safe. However, if you'd rather not use a headset, then there are plenty of resources to obtain a radiation shield for your phone.
In a separate study by the same Swedish team, they found more than seven times the risk among people using a cell phone more than 20 years and 6.5 times the risk for long-term users of cordless phones. As expected, most of the gliomas and acoustic neuromas were on the same side of the head, which was usually exposed to the phone. In the 2013 official report on the medical evidence for brain tumors, the International Agency for Research on Cancer concluded that radiation from cell phones is “possibly carcinogenic to humans”.
