I am shin datuin..a radiologic technologist..I never thought that electromagnetic radiation is harmful to our health because according to our studies.. EMR is safe (example:radiation of MRI..wifi..) I became hypersensitive to EMR after using the USB modem (the 4G internet)..Because when you download a file.. the EMR of 4G internet/USB modem boost it’s signal capacity/transmission rate and damages your cells in the body specifically to the brain.. 16 hours or above of downloading will break your immune system to electromagnetic radiation (maybe it varies on your body size)..But after the 16 hours of exposure.. my body inhibits the symptoms of feeling tired.. headache.. dizziness..nausea..fast heartbeat..I felt like someone is touching at the back of my head (occipital region).. So i shut off the USB modem and the symptoms were gone after few hours of rest.. But even now.. i’m having this problem when i’m at the High EMR areas.. so i minimize using our wifi router.. Anyway.. wifi signal or transmission can be setup to minimum capacity..So set it up before it’s too late.. Be safe guys!
The quality of the product is really good, just as good as the more expensive stickers I have purchased in the past. Its not a big deal, but the stickers I received are not star shaped. They are round/circle. I have been able to test them yet to see if they actually work. Waiting to see my brother who can test them for me. Will update this review when I find out.
To be sure, the industry could not have been pleased with some of the Interphone study’s conclusions. The study found that the heaviest cell-phone users were 80 percent more likely to develop glioma. (The initial finding of 40 percent was increased to 80 to correct for selection bias.) The Interphone study also concluded that individuals who had owned a cell phone for 10 years or longer saw their risk of glioma increase by nearly 120 percent. However, the study did not find any increased risk for individuals who used their cell phones less frequently; nor was there evidence of any connection with meningioma.36
Ionizing radiation, including x-rays and ultraviolet light, produces molecules called ions that have either too many or too few electrons. Ions are known to damage DNA and cause cancer. Cell phone radiation, like radio, TV, and visible light radiation, is non-ionizing and lacks sufficient energy to add or remove electrons from molecules, and therefore it cannot ionize and cause cancer.  According to the authors of a 2005 peer-reviewed study of 3.7 million Swedish residents, a "biologic mechanism that could explain any possible carcinogenic effect from radiofrequency radiation has not been identified." 
It is concluded that radiofrequency radiations are genotoxic as they induced chromosomal aberrations in chickpea mitotic cells and the presence of ghost cells is clear indication of their carcinogenic potential. To avoid reported DNA damages in this work cell phones should always be used either for short duration or with hands-free for long duration and they should not be kept in pockets or near body. Laptops should not be used unnecessarily for enjoyment purpose. It must be placed on desk top rather lap to minimize their exposure to human body. Further assay of carcinogenity are recommended on mouse and human cell lines.
There is a catch, though: The Internet of Things will require augmenting today’s 4G technology with 5G, thus “massively increasing” the general population’s exposure to radiation, according to a petition signed by 236 scientists worldwide who have published more than 2,000 peer-reviewed studies and represent “a significant portion of the credentialed scientists in the radiation research field,” according to Joel Moskowitz, the director of the Center for Family and Community Health at the University of California, Berkeley, who helped circulate the petition. Nevertheless, like cell phones, 5G technology is on the verge of being introduced without pre-market safety testing.26
Members of the public often ask about the cumulative exposure that a child receives when using a Wi-Fi device in a classroom in which a number of children are simultaneously using Wi-Fi. When downloading files, most of the transmissions will be from the access point, not the students’ device. When downloading and uploading only a portion of the maximum capacity of a network would be used even in a classroom filled with children using Wi-Fi. The Wi-Fi network divides RF transmissions among the access points and client devices therefore the individual RF exposure to a child in a classroom that is using a device consists of sequential exposures from all active devices, the majority of which are located at some distance away(15). For the majority of schools (20) the measurements in the current study were conducted in an empty classroom (to avoid lesson disruption) with an access point and one laptop. In three schools, measurements were conducted with students or teachers present and using Wi-Fi devices. A comparison between measurements conducted in empty classrooms and classrooms with multiple students/teachers using Wi-Fi showed no significant difference in the RF levels (p > 0.1 for all); although this may have been due to low numbers (only three schools measured with multiple users in the classroom).
The CERENAT study, another case–control study conducted in multiple areas in France from 2004 to 2006 using data collected in face-to-face interviews using standardized questionnaires (18). This study found no association for either gliomas or meningiomas when comparing regular cell phone users with non-users. However, the heaviest users had significantly increased risks of both gliomas and meningiomas.
Participation bias, which can happen when people who are diagnosed with brain tumors are more likely than healthy people (known as controls) to enroll in a research study. Also, controls who did not or rarely used cell phones were less likely to participate in the Interphone study than controls who used cell phones regularly. For example, the Interphone study reported participation rates of 78% for meningioma patients (range among the individual studies 56–92%), 64% for glioma patients (range 36–92%), and 53% for control subjects (range 42–74%) (6).
Most smartphones have settings that will help you manage your privacy and safety. You can find these controls through the settings on your phone or through the settings of a specific app. These settings may allow you to limit an application’s access to the data on your phone, including access to your location, pictures, contacts, notes, etc. You may even be able to block cookies and limit what data your mobile browser collects.
Whether you call them cell phones, smart phones or mobile devices, it seems like everyone has one. According to the wireless telecommunications industry, the U.S. now has an estimated 300 million mobile subscribers, compared to 110 million subscribers a decade ago. The increase in cell phone use has generated concern about possible health risks related to radiofrequency electromagnetic fields from this technology, and a market for shields as possible protection against the radio waves the phones emit. The Federal Trade Commission (FTC), the nation's consumer protection agency, has some practical tips to help you avoid scams and limit your exposure to electromagnetic emissions from your cell phone.
I’ve tried to stop using my laptop PC whose WiFi antennas I think were at the front edge on my lap since a highly skeevy lesion manifested at about my waistline. Same for any other wifi devices; I use a table or desk or bench or another chair to set it on now, not the lap. Testing the lesion naturally as if it might be cancerous, making it go away.
c) and before you raise the argument that visible light is itself electromagnetic radiation, with even shorter wavelengths than microwaves, electromagnetic radiation within the visible light range does not penetrate living cells and other molecular materials as X-Rays (ionising radiation) or microwaves (non-ioninsing radiation) do. Practically all visible light is reflected by our bodies, and therefore it’s energy is not absorbed by our cells and is therefore harmless.
Long-term exposure to Radio Frequency waves or microwave radiation has long been studied and shown to produce all sorts of adverse health effects. See my post on EMF Radiation Exposure Symptoms for a full list of common symptoms. Even the American Cancer Society, who in large part will not fully say that EMF radiation causes long-term harm, and instead errs on the side of not enough research, admits on their website, that:
Radiofrequency radiation from cell phones is non-ionizing and is not powerful enough to cause cancer. Ionizing radiation, including x-rays and ultraviolet light, produces molecules called ions that have either too many or too few electrons. Ions are known to damage DNA and cause cancer. Cell phone radiation, like radio, TV, and visible light radiation, is non-ionizing and lacks sufficient energy to add or remove electrons from molecules, and therefore it cannot ionize and cause cancer.  According to the authors of a 2005 peer-reviewed study of 3.7 million Swedish residents, a "biologic mechanism that could explain any possible carcinogenic effect from radiofrequency radiation has not been identified." 
Unfortunately, the current state of cell phone radiation research is similar to the early days of tobacco research. It wasn't until 1999 when the U.S. Department of Justice finally filed a racketeering lawsuit against the major tobacco companies for engaging in a "50 year scheme" to counteract any scientific evidence that showed that cigarettes are harmful to a person's health. Is the potential cell phone cancer link the same sort of scenario? Are cell phone companies funding and promoting research that "proves" no link from cell phone radio radiation in an effort to discredit those studies that are uncovering problems?
Cell phone radiation may disrupt the functioning of pacemakers. A 2005 study in the International Journal of Cardiology found that mobile phones may have "adverse effects" on pacemaker functions under certain conditions.  According to the US Food and Drug Administration (FDA), radiofrequency energy from cell phones can create electromagnetic interference (EMI) that may disrupt the functioning of pacemakers, especially if the cell phone is placed close to the heart.  The American Heart Association includes cell phones on its list of "devices that may interfere with pacemakers." 
The FCC has granted the industry’s wishes so often that it qualifies as a “captured agency,” argued journalist Norm Alster in a report that Harvard University’s Edmond J. Safra Center for Ethics published in 2015. The FCC allows cell-phone manufacturers to self-report SAR levels, and does not independently test industry claims or require manufacturers to display the SAR level on a phone’s packaging. “Industry controls the FCC through a soup-to-nuts stranglehold that extends from its well-placed campaign spending in Congress through its control of the FCC’s congressional oversight committees to its persistent agency lobbying,” Alster wrote. He also quoted the CTIA website praising the FCC for “its light regulatory touch.”31
Although melatonin and L-Carnitine offer a nutritional defense, they don’t block exposure. And that’s very hard to accomplish anyway. Look at coverage maps from cell phone companies, or notice how many Wi-Fi networks your smart phone prompts for you to join. We’re surrounded and bombarded by electromagnetic radiation. Blocking exposure is difficult but there are a few small steps you can take. For one, do not keep cell phones, laptops, and tablets close to your body. And if it’s not being used, shut them off (your wireless router too). There are also a number of devices available to counteract electromagnetic frequencies. Check out these ways to protect yourself from laptop radiation and cell phone radiation, too.
1. Be careful what you share. “Use the same good sense about what you post from your phone as from a computer. Once they’re posted, text, photos, and video are tough to take back, can be copied and pasted elsewhere, and are up there pretty much forever. Think about the people in them (including you!). Reputations are at stake.” – Tips for Smart Cellphone Use, Connect Safely; Twitter: @ConnectSafely
