A phone's specific absorption rate (SAR) reveals the maximum amount of radiation the human body absorbs from the phone while it's transmitting. SAR testing ensures that the devices sold in the U.S. comply with the Federal Communications Commission (FCC) SAR exposure limit, but the single, worst-case value obtained from this SAR testing is not necessarily representative of the absorption during actual use, and therefore it is not recommended for comparisons among phones. In short, selecting a lower SAR phone will not reliably ensure lower radiation absorption during use. The FCC has more information at Specific Absorption Rate (SAR) For Cell Phones: What It Means For You.
gamma rays produce virtually no electricity in the human body because the actual inherent energy of gamma rays that actually hits molecules is next to 0. for gamma rays to produce any electricity they would need to hit something much more dense – like lead and for you to generate any significant electricity from gamma rays hitting the earth you would need a huge slab of it.

The key factor when selecting a cell phone case is making sure that you choose the exact one your phone needs. Cases are specific to not only brands of cell phone, but specific models as well. For example, if you have version three of a cell phone model, it may not fit a version six, and vice versa. Make sure that you know exactly what case you need. The cases protect the corners and back of the phone, and a clear tempered glass or Plexiglas shield protects the face. This glass or film is usually scratch- and smudge-resistant, and the cases are rubber or polycarbonate. Some cases have clips on the back that allow you to connect the phone to a belt or bag. Many cases are black, but multiple colors and patterns are available too.

In a real-world setting, August, having ES herself, hopes people who are trying to control their exposures, will refer to the following chart: The lowest level August recommends EVER being exposed to--for even a brief time is less than 1 Volts per meter--which is actually the level of exposure you can get from most WiFi's when you're between 15 and 20 fee away.  And August level is for people who are not experiencing symptoms of sensitivity, live in real-world(WiFi's, cellphone connected) situations. 

The World Health Organization International Agency for the Research on Cancer’s classification of wireless radiofrequency frequencies a Class 2B carcinogen includes wireless radiation from any transmitting source such as cellphones, baby monitors, tablets, cell towers, radar, other wifi, etc. The radiofrequency classification applies to RF-EMF in the range of 30 KHz to 300 GHz emitted from any device. Cell phone frequencies commonly start at 900 MHz (with some cell phones having up to 7 antennas all at different frequencies) and Wi-Fi device frequencies are at 2.45 GHz and 5GHz.
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]

The device comes in a variety of forms ranging from the $39 Aries Shield ("a silicon based micro processor that ... decomposes oscillations of electromagnetic fields") to the $249 Aires Defender Utility (which "has two next generation 9 core silicon based micro processor (sic) that provide universal protection from electromagnetic smog of the broadband frequencies").
We do have evidence that cellphones (or WiFi) do NOT cause an increase in brain tumors. Look at the time period over which cellphone use became common -- say, over the last twenty years. During that time, the incidence of brain tumors has remained absolutely flat. With over four billion people using cellphones (or WiFi) today, if there was any influence on the development of brain tumors, we would be seeing that by now.

As iPhones go, the iPhone SE is a bargain, but it doesn’t come cheap. Don’t let the pint-sized package fool you, however. The iPhone SE has a fast A9 processor, which is the same processor used in the iPhone 6S. It also comes with a crisp display and runs the latest version of iOS. The iPhone SE is a great choice for a child, too, given it features built-in parental controls. You can prevent your child from accessing the internet and using specific apps, for instance, or prevent them from making purchases in the App Store.

One of the convenient features of having a smartphone is to quickly access email or social media accounts with just a tap of a finger. However, this also means that you are always connected to accounts that may contain sensitive information. Consider logging out of certain accounts if you can so that others can’t access those accounts if they are using your phone. Keep in mind that depending on the type of phone you have, you might not be able to log out of some accounts, such as email accounts, but may have to remove the entire account from your phone. In this case, make your decision based on your own privacy and safety risk. While it may be inconvenient to access the account through the browser instead, it may be safer.
If cell phones were causing cancer we could expect a significant rise in the rate of brain and other related cancers. According to the National Cancer Institute, there was no increase in the incidence of brain or other nervous system cancers between the years 1987 and 2005 despite the fact that cell phone use dramatically increased during those same years. [6] Between 2004 and 2010 there was still no significant change in the incidence rate of brain tumors. Between 2004 and 2010 there was a slight increase from 209 cases to 221.8 cases per 100,000 people, but this slight increase was attributed to better tracking and recording of cases. [43] During the same time period, cell phone use increased 62.7% from 182,140,362 subscribers in 2004 to 296,285,629 in 2010. [44]
There is only one legitimate method of measuring cell phone radiation recognized by every major health authority and government in the world as well as by the cell phone industry itself, referred to as "SAR". SAR testing measures the "Specific Absorption Rate" of radiation at multiple depths and locations on the head and body in order to quantify how much radiation is actually penetrating it with and without certain safety devices. You can see a SAR test of the R2L device by watching the video below.
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.
Turn Off WiFi Before Bed: This is one of our favorites in our Tech Wellness Top 10 easy ways to make wireless safer: We call it our Wi-Fi Kill-switch so you don't have to get close the Router. It's as important as WiFi Router placement. The simple step of hitting the off switch can lead to a better night’s sleep. Or, try this timer that can shut or kill that nasty Wifi energy any time of day or night. When on, a WiFi signal may interfere with our brains during sleep, so by turning it off we reduce exposure and hopefully rest more deeply.
We actually debated including some links to some of the worst offenders just to show you how outlandish (and unscientific) the claims they make are, but we couldn’t stomach giving them even a penny of ad revenue. If you want to see how bad things are you can search for “Wi-Fi dangers” on Google where, it becomes clear, the page rank algorithm doesn’t always reward pages with the most scientific merit.

This is extremely important for a lot of reasons but will be crucial for any step to reducing radiation. Having a quality EMF meter will allow you to determine what kind of radiation devices in your home are emitted, as well as how much. This will also be crucial in understanding how different changes are improving this I would highly recommend either the TriField TF2 (read my review), or Meterk (read my review) if you need a lower cost EMF meter.
The purpose of this study was to reveal whether long term exposure (over a year) of 2.4GHz frequency RF radiation will cause DNA damage of different tissues such as brain, kidney, liver, and skin tissue and testicular tissues of rats. Based on the DNA damage results determined by the single cell gel electrophoresis (Comet) method, it was found that the % tail DNA values of the brain, kidney, liver, and skin tissues of the rats in the experimental group increased more than those in the control group. The increase of the DNA damage in all tissues was not significant (p>0.05), however the increase of the DNA damage in rat testes tissue was significant (p<0.01). In conclusion, long-term exposure to 2.4GHz RF radiation (Wi-Fi) does not cause DNA damage of the organs investigated in this study except testes indicating  that testes are more sensitive organ to RF radiation.
The HPA also says that due to the mobile phone's adaptive power ability, a DECT cordless phone's radiation could actually exceed the radiation of a mobile phone. The HPA explains that while the DECT cordless phone's radiation has an average output power of 10 mW, it is actually in the form of 100 bursts per second of 250 mW, a strength comparable to some mobile phones.[8]

This review presents the findings of more than 100 studies that were published in reputable scientific journals. Most of these studies confirm potential health impacts as were summarized in the joint "Nicosia Declaration on Electromagnetic and Radiofrequency Radiation" by the Cyprus and Austrian medical associations in 2017: “Potential health impacts of non-ionizing radiation from EMF/RF (electromagnetic fields/radiofrequencies) of 30 KHz – 300 GHz include carcinogenicity (Class B, IARC 2011), developmental neurotoxicity, effects on DNA, fertility, hypersensitivity and other serious effects are well documented in peer reviewed studies. RFR can increase oxidative stress in cells and lead to increase of pro-inflammatory cytokines and lower capacity to repair DNA single- and double-strand breaks. Cognitive impairments in learning and memory have also been shown. These effects can occur at levels well below existing limits of ICNIRP. ... Exposure to EMF/RF at an early developmental stage is of particular concern due, amongst other, to greater absorption and potential effects on the developing developing brain, nervous system as well as their reproductive system, may induce cancer, cognitive effects, etc.” (www.diagnose-funk.org/publikationen/artikel/detail&newsid=1242 and www.cyprus-child-environment.org/easyconsole.cfm/id/428).

11. Sign out of your banking app when finished. “Don’t save your banking app ID on your device: Most apps give consumers the option to save their ID to that device. But if the smartphone or tablet falls into the wrong hands, the thief will have access to sensitive information, including balances and critical account numbers. Also make sure you sign out of the app after each session. Most apps automatically sign users out after a set time without detecting activity, but it’s safer to sign out immediately after each use.” – Stephen Ebbett, 6 Tips for Avoiding Identity Theft When Mobile Banking, About Money; Twitter: @AboutMoney
