A method of simulating thermal mapping of positioning laptop on laps of an adult man was developed. To tackle this problem, we exploited computer simulation and, to make the simulation close to the actual problem, we created 3D models of an actual laptop (Sony FW 590 Gab), antennas, and human phantom with inhomogeneous body, large number of tissues, and dispersion properties. We employed a commercial laptop Wi-Fi antenna at 2.4 GHz and a dipole antenna at 5 GHz, thermal sources with radiation powers, and human body voxel consisting of 97 tissues which were described previously. In the simulation, maximum SAR in human body was calculated 0.37 × 10−3 and 0.13 × 10−1 (W/kg) at 2.4 and 5 GHz, respectively, which was negligible according to IEEE standards; thus, the major calculated temperature elevation was due to laptop thermal sources. The temperature in glans penis, lap skin, lap muscles, and testes increased up to 37.8, 42.9, 38.8, and 37.2 °C, respectively, which was in line with clinical studies of thermal effect. Hence, the proposed method can be replicated for other scenarios. It is worth noting that the presented result cannot be easily generalized to other devices or human models. However, the whole method is replicable for similar phenomena. The recommended subject for future works can be used with the presented method for determining the effect of laptop and other devices on adult pregnant women and similar cases.
The FCC’s safety standards for cell phone radiation were based on studies conducted in the 1980s, These studies have long since been rendered obsolete by newer research. Yet for years the FCC refused to update or even review its standards. Instead, the federal agency simply sat on its hands while cell phones became ever more powerful and ubiquitous.
The aim of this study was to investigate the possible protective role of melatonin on oxidative stress induced by Wi-Fi (2.45 GHz, 60min/day for 28 days) EMR in laryngotracheal mucosa of rat. In comparison to control and sham groups, RFR-exposed animals had higher lipid peroxidation levels and lower glutathione peroxidase levels, while the RFR-exposed animals treated with melatonin had significantly lower lipid peroxidation levels and increased glutathione peroxidase activity compared with controls. Results show that there is an apparent protective effect of melatonin on the Wi-Fi-induced oxidative stress in the laryngotracheal mucosa of rats by inhibition of free radical formation and support of the glutathione peroxidase antioxidant system.

Performance is good, delivered by the Snapdragon 450, though it might struggle a little bit with multitasking. We found swapping between demanding apps caused the phone to slow down a bit — but it also handled simple games fairly well, and provided solid enough performance most of the time. There are plenty of storage options too, with 32GB available as a base option, and the ability to add a MicroSD card for extra room.


You can search for the most popular cell phone cases and covers, browse cases and covers by brand, and even refine your search by need. Cell phone cases provide a variety of protection. Some people put a large emphasis on military-grade protection, to ensure that all angles of their case are secure, no matter the terrain. Others may desire cases that give easy access to headphone ports or charging outlets, to have access to home speakers or audio cables. The engineering of cases can become even more specific—right down to the beveled edges that raise your screen protectively above a flat surface or the grip finish smoothly designed onto the back of your phone to ensure maximum ease in typing. Whatever your need, Amazon is sure to carry the brand, features, and colors you care about. Check the Deals page regularly to even see some of your favorite cases on discount. Amazon is sure to carry the widest selection of cases; you just worry about carrying yours.
According to an anonymous questionnaire, daily active cell phone usage was divided into three groups as following: Group A, < 30 min/d; Group B, from 30 min/d to 2 h/d; and Group C, > 2 h/d. Habits of carrying a mobile phone was recorded as (A) in the pocket of trousers, (B) in a handbag, or (C) in the pocket of jackets. Wireless internet usage was divided in to three groups, Group A: < 30 min/d; Group B, from 30 min/d to 2 h/d; and Group C, > 2 h/d. Internet usage types recorded as wireless or not.
We asked Dr. George Carlo his thoughts on EMF cases and shielding products, “most offer some protection, some of the time, to some people, because they can alter the immediate electromagnetic field environment around the person,” and immediately emphasizes the importance of “some,” which seems to tell us that it’s vastly unpredictable. “All waveforms in the environment are highly variable and they interact with other factors in the environment that make them even more variable.” This pretty much sums up that the artificial electromagnetic energy universe is vastly unpredictable.
PURPOSE: MicroRNAs (miRNA) play a paramount role in growth, differentiation, proliferation and cell death by suppressing one or more target genes. However, their interaction with radiofrequencies is still unknown. The aim of this study was to investigate the long-term effects of radiofrequency radiation emitted from a Wireless Fidelity (Wi-Fi) system on some of the miRNA in brain tissue.
The HPA's position is that “...radio frequency (RF) exposures from WiFi are likely to be lower than those from mobile phones.” It also saw “...no reason why schools and others should not use WiFi equipment.”[4] In October 2007, the HPA launched a new “systematic” study into the effects of WiFi networks on behalf of the UK government, in order to calm fears that had appeared in the media in a recent period up to that time".[13] Dr Michael Clark, of the HPA, says published research on mobile phones and masts does not add up to an indictment of WiFi.[14][15]

In the Lancet article outlining their considerations, that IARC states that epidemiological studies that follow humans who use WiFi and cell phones for a few years are not conclusive. However, rodent studies that follow the animals throughout their lifetime find that wireless radiation does cause cancer or worsen cancer prognosis. The same animal studies also observed other changes in the brain and blood brain barrier in animals that are exposed to the radiation.

Radiation is also the thing that bathes the world in warm sunlight, and makes life on Earth possible. Radiation is also the reason we can turn on a radio and hear music without wires. Radiation is how we change the channels on our television (and for anyone getting their TV fix via over-the-air channels or satellite TV, how the programming gets delivered to their home in the first place).


The RF signals from cell phones, as well as Bluetooth and WiFi, are considered nonionizing forms of radiation. That means unlike ionizing radiation—from, say, ultraviolet light from the sun, medical tests such as CT scans or X-rays, or nuclear explosions—they don’t carry enough energy to directly break or alter your DNA, which is one way cancer can occur.


We have a safe search tools for kids. It is more of a phone friendly version of our site that automatically ensures safe search is on at http://www.safesearchkids.com/app.html or enter “Safe Search Kids” in your phones app store to get the links. Having your tweens and teens agree to use this version of search will automatically ensure safe filtering is always on. That said, you still need to set up guidelines that allow you to view history on their phone when needed, as well has having them promise to not delete their history knowing you may look at it.

According to scientists involved in the process, the WHO may decide later this year to reconsider its categorization of the cancer risk posed by cell phones; the WHO itself told The Nation that before making any such decision, it will review the final report of the National Toxicology Program, a US government initiative. The results reported by the NTP in 2016 seem to strengthen the case for increasing the assessment of cell-phone radiation to a “probable” or even a “known” carcinogen. Whereas the WHO’s Interphone study compared the cell-phone usage of people who had contracted cancer with that of people who hadn’t, the NTP study exposed rats and mice to cell-phone radiation and observed whether the animals got sick.47
You’ll find no shortage of articles on the dangers of just about anything if you look around the Internet. Articles about how dangerous modern medicines are, how dangerous cell phones are, how dangerous cooking your food in a microwave is, and yes, how dangerous Wi-Fi is. People claim that Wi-Fi routers keep them awake at night, cause cancer, cause hyperactivity in children, and all manner of unsupported and nonsensical claims.
Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. Because of changes in cell phone technology and increases in the number of base stations for transmitting wireless signals, the exposure from cell phone use—power output—has changed, mostly lowered, in many regions of the United States (1).
We requested semen for analyses from the male patients coming to our infertility division and also asked them to fill out an anonymous questionnaire. We queried their mobile phone and wireless internet usage frequencies in order to determine their radiofrequency-electromagnetic radiation exposure. A total of 1082 patients filled the questionnaire but 51 of them were excluded from the study because of azoospermia. 
You hit the nail on the head when you say that distance is key when it comes to EMF exposure. The solutions you sell will definitely help provide that separation. That said, our products are different in that they shield the user from EMF while allowing them to use the device as they normally would, without needing to hold their device by a rope or placing it in a faraday cage that eliminates signal altogether.
“Everyone knows that if your research results show that radiation has effects, the funding flow dries up,” Leszczynski said in an interview in 2011. Sure enough, the Radiation and Nuclear Safety Authority of Finland, where Leszczynski had a long career, discontinued research on the biological effects of cell phones and discharged him a year later.46
Don’t text or handle your phone while driving. Texting or even touching your phone while driving is dangerous and illegal in many states. If you must speak on the phone, use a speaker or headset and hands-free controls. Never text, send or read email or post online and if you use your phone for navigation or listening to music or podcasts, set it before you leave or use hands-free voice recognition.

The NTP study was to be peer-reviewed at a meeting on March 26–28, amid signs that the program’s leadership is pivoting to downplay its findings. The NTP had issued a public-health warning when the study’s early results were released in 2016. But when the NTP released essentially the same data in February 2018, John Bucher, the senior scientist who directed the study, announced in a telephone press conference that “I don’t think this is a high-risk situation at all,” partly because the study had exposed the rats and mice to higher levels of radiation than a typical cell-phone user experienced.50

As I demonstrate in the video, you can see that with this router, I am exposed to about 100 times more Radio Frequency (RF) energy when I’m next to the router versus standing 20 feet away. This measurement video, like the others in our Video Library, give you an example of the varying levels of energy coming from our WiFi Routers.  If I was using the same meter on say, your WiFi, the measurements could vary widely. 
10. Your house may be burglarized due to social media. “If you spend any time with social media, (Facebook, Twitter, etc.) You have probably found that you can “check-in” somewhere to let all your friends know what you’re up to, and maybe even stop by for coffee. But if your security settings on the social networks are not set properly, you could just as easily be telling robbers that your house is vacant right now, which they will find most helpful when they clean you out. Sometimes, they will come back in a couple of months, to get this stuff you bought with the insurance money, too. Occasionally, they will look for important documents to commit identity theft. All told, checking-in may be one of the most reckless cell phone safety errors we can commit.” – Cell Phone Safety Identity Theft and Cell Phone Security, About Money; Twitter: @AboutMoney
