Cell-phone designs have changed a lot since the studies described above were completed. For example, the antennas—where most of the radiation from cell phones is emitted—are no longer located outside of phones near the top, closest to your brain when you talk, but are inside the phone, and they can be toward the bottom. As a result, the antenna may not be held against your head when you’re on the phone. That’s important because when it comes to cell-phone radiation, every millimeter counts: The strength of exposure drops dramatically as the distance from your body increases.
Some products (http://www.safecell.net/reports01.html for example) are tested using a piece of shielding material in a laboratory test jig. These tests legitimately show the amount of radiation which penetrates the shield, but results will be very different when compared to putting a small amount of the same shield on a large transmitter like a cellphone. Remember, the entire phone radiates. Placing a small amount of shielding, even if it is an effective shielding material, only shields that small area at best. Think about this analogy: no light will penetrate a penny as it is a very effective light shield, but it is silly to think that holding a penny up to the sun will put you in darkness.
We’ll see how it holds up, but out of the box this case is wonderful. No problems at all with it interfering with the cameras or the four microphones in the iPhone 7. In fact, my last case must have interfered with the mics because people I call often are now saying the sound is much better on their end, and this is when the case is closed with speakerphone on. // This case is put together nicely. Good stitching, nice texture. I am a vegan so I feel good using it. // I haven’t used the card or money slots so I can’t speak about those. It’s not important to me anyway. // All-in-all I’m very pleased. I was a little apprehensive spending $35 or whatever amount it was, but this case is quality. Hope it blocks the bad stuff like they say it does. I feel the company is very straightforward and honest in their product information and didn’t make outlandish claims. Great case! // Update, 5 months later. Perfect. Not a stitch broken. It’s holding up extremely well. Very pleased.
How many times do you put your cell phone in your back pocket when dashing to work or to a meeting? Maintaining a close proximity of cell phones to reproductive organs may not be the wisest idea when it comes to protecting reproductive health. SYB (Shield Your Body) Pocket Patch is a thin, white, and extremely lightweight patch that can be easily ironed on to the inside of pockets, effectively reducing up to 99% of cell phone radiation. Despite the powerful radiation-blocking effects of the hypoallergenic patch, it doesn't interfere with your phone's battery life or its normal behavior. It can be easily ironed on to any fabric, and tests show that the SYB maintains its potency even after 30 washes. Each patch is 5.5" tall and 3.75" wide, perfect for basic pockets in most pants, sweaters, and jackets.
Protect your brain from RF (radio-frequency) pollution with this handsome baseball style hat. Specially designed to shield the head from frequencies from below AM through microwave, including cellular phone frequencies. Lined with sophisticated Staticot fabric woven from ployester/cotton with an ultrathin stainless steel fibers excellent radiation protection. This gives this unique fabric a truly comfortable, natural feel and the durability and washability of cotton, but with exceptional reflective characteristics.
Only 0.010 inch thick, PaperSHIELD is flexible and can be easily cut with a scissors and shaped by hand into simple or very complex shapes. High saturation and moderate permeability make this ideal for shielding weak magnets, or stronger magnets with many layers of shielding. This material is particularly suited for achieving precise levels of partial shielding as you can add exactly the right number of layers to achieve the desired result. White paper on one side can be imprinted (by you). Peel and stick adhesive on the other side permits easy and semi-permanent mounting almost anywhere. Magnets will stick to it nicely.
As to increases in brain tumors tied to cell phone use, it’s too early to tell due to a lack of hard data, says Dr. Carlo. “We’re never going to see that in time to have it matter. Here in the US, we’re six years behind in getting the brain tumor database completed, and currently the best data are from 1999. By the time you see any data showing an increase, the ticking time bomb is set.”
Taken together, the findings “confirm that RF radiation exposure has biological effects” in rats, some of them “relevant to carcinogenesis,” says Jon Samet, a professor of preventive medicine and dean of the Colorado School of Public Health, who did not participate in either study. Samet, however, cautioned the jury is still out as to whether wireless technology is similarly risky to people. Indeed, heart schwannomas are exceedingly rare in humans; only a handful of cases have ever been documented in the medical literature.
Like we talked about in the last section, SAR limits that are reported are the maximum possible radiation emitted from the device, however, this level is not what is common with the regular use of the device. Just because one cell phone has a higher maximum SAR level, doesn’t mean that the radiation level of normal use isn’t higher or lower than another device with a different maximum SAR level.
Laptop computers are best placed on a table at as much of an arm’s length away as possible to minimize radioactive contact. If you must use your laptop on your lap, you can purchase a laptop cooling pad which will add a bit of extra space between the device and your body. Even better are laptop cases specifically designed to shield against radiation.
In the studies, the researchers looked at a whole slew of health outcomes (like offspring survival, bodyweight changes, and body temperature changes), but importantly, they also looked at brain tumors, including gliomas. They exposed the animals to radio frequency radiation for up to nine hours a day over two years, and then examined more than 40 tissues in each animal. And they had a control group that wasn’t exposed to radiation for comparison.
By not formally reassessing its current limit, FCC cannot ensure it is using a limit that reflects the latest research on RF energy exposure. FCC has also not reassessed its testing requirements to ensure that they identify the maximum RF energy exposure a user could experience. Some consumers may use mobile phones against the body, which FCC does not currently test, and could result in RF energy exposure higher than the FCC limit.
The tricky part about measuring the radiation from a cell phone is that the emission strength varies widely over time. There will be strong bursts of varying intensity, followed by quiet periods. This makes it hard to compare "apples to apples". Also, because you are measuring up close to the source, you must use a near field meter AND you must maintain the position of the meter very precisely.
I'm glad I spent the money to get this protection. Again, I consider this an "insurance policy" and hope cell phone radiation is over hyped. However, mounting evidence seems to indicate otherwise, so I feel more comfortable knowing I'm taking proactive steps to protect against a possible health problem I and my family might face in the future from long and close exposure to cell phones close to the body and head.
As our video points out: Measurements will vary with signal strength and other factors and that includes ambient energy. I talk about ambient energy in a lot of my videos-it's the energy that's in whatever environment I happen to be measuring in that's coming from a source of wireless energy that isn't the subject of what I'm measuring. My home is not a lab of course, but fortunately it's always measured very low for RF radiation.
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.
