This Ethernet cable can be a source of RF radiation and so needs to be shielded. There are lots of different qualities of cable category 5, 6, 7 etc. I recommend buying at least Cat 6a SSTP (screened shielded twisted pair) Ethernet cable. Maybe the cable that came with your modem/router is Cat 6a SSTP. In that case you’re OK. If in doubt change it.
When using your phone or tablet, consider keeping it away from your head and body. That is particularly true in areas where the cellular signal from towers is weak—when your phone has only one bar, for example—because phones may increase their power then to compensate. To do that, you could try texting or video-calling when possible, using the speaker phone on your device or a wired or Bluetooth headset, carrying your phone in a bag instead of stowing it in your pocket, and not resting your tablet on your body for a long period of time. When you go to bed, consider storing your phone away from where you sleep, switch it to airplane mode, or turn it off entirely.
Moving the meter around the case, we detect readings on the side, back and front of the case. We use the multi-directional TES 593 meter which measures 10 MHz to 8GHz. We use the unit of micro-watts per square centimeter, which looks like this little symbol: μW/cm² and we use it on the max setting which shows the maximum measured value. In non-science speak: the highest level of RF we see, which could be from the back the side or the front. 
The most critical concept when it comes to talking about radiation is the distinction between ionizing and non-ionizing radiation. Ionizing radiation is the dangerous stuff and includes x-ray radiation, gamma radiation, and some amount of ultra-violet light on the high end of the ultra-violet spectrum. The key element here is the wavelength of the radiation type.
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.

Our homemade demonstration of all the cases uses a working phone. Not the shielding material by itself, but the actual "shielding" SafeSleeve, Pong, Reach,  Vest, ShieldMe, and Defender Shield cases. First we get RF power density measurements from a phone that's on a call and then, in the same location, within minutes of the first reading, we place the same phone as it's engaged in a call into each case and we take additional reading with the meter.
It’s also packing a decent camera, so your kid can share selfies without worrying about the quality. It’s not perfect, and the battery life might not last as long as you’d like — but Motorola’s TurboPower charging means 15 minutes of charging can give six hours of battery life. Sit your kid down to dinner and plug their phone in, and it should be more than ready to see them through to bedtime. All in all, the Moto G6 is an extremely solid phone that should serve your child well.
Our cell phones for hazardous areas ensure the safety of your workers in all situations. We offer intrinsically safe cell phones for Zone 1 / Class I (ATEX, IECEx) and explosion proof cell phones for Zone 2 / Class II (NEC). Our cell phones are available with lone worker protection (LWP) and our range of products also includes an intrinsically safe smartphone, the Smart-Ex® 01.

This study was aimed at investigating the alteration of antibiotic resistance of Klebsiella pneumonia, after exposure to Wi-Fi 2.4 GHz electromagnetic radiofrequency radiation from a Wi-Fi router for 3, 4.5 or 8 hours. The findings of this study show a statistically significant rise in the sensitivity of Klebsiella pneumoniae to different antibiotics after 4.5 hours of exposure to 2.4 GHz Wi-Fi radiation, followed by a fall after 8 hours of exposure. These observations can be interpreted by the concept of non-linearity in the responses of Klebsiella pneumoniae to different antibiotics after exposure to electromagnetic radiofrequency radiation.
Like any investment worthy of protection, cell phones are no exception. Amazon carries a wide variety of cell phone cases and covers to meet your needs. Whether you’re in the market to find an accessible armband to use your cell phone during workouts, or a battery charger case to boost the power on your cell phone’s dying battery life, Amazon offers a wide selection so you can choose the case or cover that best fits your lifestyle.
A 2012 study by NCI researchers (25) compared observed glioma incidence rates in U.S. SEER data with rates simulated from the small risks reported in the Interphone study (6) and the greatly increased risk of brain cancer among cell phone users reported in the Swedish pooled analysis (19). The authors concluded that overall, the incidence rates of glioma in the United States did not increase over the study period. They noted that the US rates could be consistent with the small increased risk seen among the subset of heaviest users in the Interphone study. The observed incidence trends were inconsistent with the high risks reported in the Swedish pooled study. These findings suggest that the increased risks observed in the Swedish study are not reflected in U.S. incidence trends.

The most compelling evidence though comes from a Swedish team of cancer experts whose research stretches back 15 years. The results clearly demonstrate “a consistent association between long-term use of cell phone and cordless phones and glioma and acoustic neuroma”. Overall, they found that using a cell phone for more than a decade significantly increases the risk of a malignant tumour by almost two times with an analogue cell phone and by nearly four times with a digital phone. Interestingly, the risks were even higher for people who had started using mobiles as teenagers.
