The frequency of radiofrequency electromagnetic radiation ranges from 30 kilohertz (30 kHz, or 30,000 Hz) to 300 gigahertz (300 GHz, or 300 billion Hz). Electromagnetic fields in the radiofrequency range are used for telecommunications applications, including cell phones, televisions, and radio transmissions. The human body absorbs energy from devices that emit radiofrequency electromagnetic radiation. The dose of the absorbed energy is estimated using a measure called the specific absorption rate (SAR), which is expressed in watts per kilogram of body weight.

In 2011, two small studies were published that examined brain glucose metabolism in people after they had used cell phones. The results were inconsistent; whereas one study showed increased glucose metabolism in the region of the brain close to the antenna compared with tissues on the opposite side of the brain (26), the other study (27) found reduced glucose metabolism on the side of the brain where the phone was used.

The best things you can do are to dramatically lower the EMF radiation in your home by using less wifi, using ethernet instead, and a ton of other steps. Check out my posts “11 Ways To Reduce Computer EMF Exposure,” “11 Ways To Reduce EMF Exposure,” and “How To Eliminate EMFs In The Bedroom” for a whole wealth of helpful tips at lowering your exposure to EMF radiation.

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.
The very next day, a livid Tom Wheeler began publicly trashing Carlo to the media. In a letter he shared with the CEOs, Wheeler told Carlo that the CTIA was “certain that you have never provided CTIA with the studies you mention”—an apparent effort to shield the industry from liability in the lawsuits that had led to Carlo’s hiring in the first place. Wheeler charged further that the studies had not been published in peer-reviewed journals, casting doubt on their validity.10

The answer is yes, it can.  Will it always make people sick? No. Dr. George Carlo explains that there is most definitely a biological response to what he refers to as Information Carrying Radio Waves (ICRW-energy fields from many wireless devices).  When you're exposed to ICRW  a process of adaptation and compensation occurs in your body.  He has a great program that can help people adapt. 
The aim of this study was to investigate the effects of  prenatal and postnatal 2450 MHz electromagnetic field exposure (1hy/day from intrauterine or postnatal period) on the growth and development of female Wistar rats. Birth masses of the groups were similar (p > 0.05), however mass gain per day was significantly lower and the puberty was significantly later in the prenatal group. Brain and ovary TOS and OSI values in the prenatal group were significantly increased (p < 0.05) compared to the control group and serum LH levels of the prenatal and postnatal groups were increased, although serum FSH, and E2 values did not differ among the groups (p > 0.05). Histological examinations of the specimens revealed no statistically significant difference between the groups (p > 0.05). Exposure to 2450 MHz EMF, particularly in the prenatal period, resulted in postnatal growth restriction and delayed puberty in female Wistar rats. Increased TOS and OSI values in the brain and ovary tissues can be interpreted as a sign of chronic stress induced by EMF.
Lack of definitive proof that a technology is harmful does not mean the technology is safe, yet the wireless industry has succeeded in selling this logical fallacy to the world. In truth, the safety of wireless technology has been an unsettled question since the industry’s earliest days. The upshot is that, over the past 30 years, billions of people around the world have been subjected to a massive public-health experiment: Use a cell phone today, find out later if it causes cancer or genetic damage. Meanwhile, the wireless industry has obstructed a full and fair understanding of the current science, aided by government agencies that have prioritized commercial interests over human health and news organizations that have failed to inform the public about what the scientific community really thinks. In other words, this public-health experiment has been conducted without the informed consent of its subjects, even as the industry keeps its thumb on the scale.27
42. Limit your child’s time on the phone. There’s much discussion about how much screen time is good for kids and teens today, and today’s wireless devices provide access to all the games, chatting features, web browsers, media, and apps they could possibly consume in a lifetime. Setting clear limits on smartphone usage will help you keep screen time within reasonable limits. “Half an hour of screen time is recommended for children 4-5 years old; an hour for ages 5-10; and two hours for high school aged kids.” – Melanie Medina, Growing up Digital – Cell Phone Safety for Kids, Identity Force; Twitter: @IdentityForce
Thank you for this information. I will be looking in to all of this. We have shut off our wifi and have hardwired our house. A cell tower was put in to our neighborhood .08 mile away 5 years ago and we’re just now looking in to the implications of living so close to one. We have a 3 1/2 year old and a 9 month old. My 3 1/2 year old is always complaining of her eyes hurting or a headache. I’m thinking it’s time to sell and move. Thank you again! I appreciate you getting back with me.

An analysis of data from all 13 countries participating in the Interphone study reported a statistically significant association between intracranial distribution of tumors within the brain and self-reported location of the phone (7). However, the authors of this study noted that it is not possible to draw firm conclusions about cause and effect based on their findings.

Purpose: This article is a systematic review of studies on the effects of non-ionizing radiation at the microwave (MW) frequency of 2.45 GHz (2450 MHz), which is predominantly used in WLAN/Wi-Fi applications (wireless local area network) and microwave ovens. Newer WLAN standards also use the frequency ranges of 5 GHz, 6 GHz, and 60 GHz. WLAN, referred to generically in this review also as Wi-Fi, has become the technology of choice for many wireless applications because providers do not require a license, making the service free to users. To meet users’ desire to be online all the time, more and more WLAN antennas (access points, femtocells, routers) emitting pulsed 2.45 GHz radiation are being installed at libraries, hospitals, hotels, airports, railway stations, shopping malls, public places, and in buses, subways, and passenger trains. Wi-Fi consoles are used to play games. Office and household appliances are also fitted with Wi-Fi antennas. Residential routers often contain two Wi-Fi transmitters. As part of its digital learning initiative, the German Conference of Ministers of Education has decided to provide all schools with Wi-Fi networks. The extensive body of research on the health risks of Wi-Fi radiation is generally not considered by policy-makers or in the public debate.
Ionizing radiation gets is name because it has enough energy to excite electrons and knock them out of their orbit, or ionize, them. Extensive exposure to this kind of radiation is highly detrimental to the your health, and even low but persistent exposure over time can significantly increase your risk of cancer as exposure can mutate your cells. Even when used for beneficial purposes (like using an x-ray machine to diagnose a patient), the exposure is carefully controlled by the use of lead vests, shielding material, and so on so that the patient and the operator of the machine are given as minimal exposure as necessary. If you’re worried about radiation, this is the radiation you should be worried about. (And even then you shouldn’t be that worried as the amount of radiation you’re exposed to during routine medical procedures is, over the course of your lifetime, less than the amount of radiation you’re exposed to over the same period on the aircraft flights you take for business and vacations.)
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.”
