48. Encourage your children to talk to you about their conversations with friends and experiences online. Make them feel comfortable talking to you if they are made to feel uncomfortable by anyone through any service while using their device. “Tell an adult you trust if you receive anything on your phone—a call, a text message, an email, a picture, or voicemail message—that makes you uncomfortable.” – Cell Phone Savvy, National Crime Prevention Council; Twitter: @McGruffatNCPC
36. Teach your kids to ignore anonymous calls or texts. It’s one thing for adults to choose to answer anonymous calls or text messages, but kids may not always know how to detect a scammer and may unknowingly reveal personal information that could be used in malicious ways. “An anonymous call could be someone trying to extract personal information. An anonymous text could be phishing.” – Rob Zidar, 13 Cell Phone Safety Tips for Teens, Pre-Teens and Their Parents, Lawrenceville Patch; Twitter: @LawvilleNJPatch

BACKGROUND: The use of devices emitted microwave radiation such as mobile phones, wireless fidelity (Wi-Fi) routers, etc. is increased rapidly. It has caused a great concern; the researchers should identify its effects on people's health. We evaluated the protective role of Vitamin C on the metabolic and enzymatic activities of the liver after exposure to Wi-Fi routers.

Lloyd is correct. I’ve worked in wireless equipment design for over 30 years, from 30kHz to 3GHz, milliwatts to many-watts. In the late 2000’s I personally set the safety standards for wireless charging (WPC’s “Qi” format) after lengthy research. Starting at 400MHz and above, DNA strands can be broken or inflicted with sequence translocation when the applied fields excite mechanical shake, twist, and compression resonances of the helixes. Those would be cancer-provoking damage. Below 300MHz I’m not aware of significant non-thermal biological effects, which explain how we’ve been “lucky” with AM/FM radio, walkie talkies, CB’s, shortwave, and VHF TV not harming people en masse.
"For example," Johnson said, "what does a fractal like pattern have to do with a hologram? The answer is, of course, nothing that is apparent. Then there is a truly convoluted assertion that cell phones can be instrumental in ‘psychoemotional' effects on humans because of their lower-frequency outputs. This too, is gibberish. In short, this is technobabble that will potentially snow someone who has no science background."
This study was performed to understand the effect of short (15 days) and long-term (30 and 60 days) low-level 2.45 GHz MW radiation exposure on hippocampus with special reference to spatial learning and memory and its underlying mechanism in Swiss strain male mice, Mus musculus. We observed that, short-term as well as long-term 2.45 GHz MW radiation exposure increases the oxidative/nitrosative stress leading to enhanced apoptosis in hippocampal subfield neuronal and nonneuronal cells. Present findings also suggest that learning and spatial memory deficit which increases with the increased duration of MW exposure (15 < 30 < 60 days) is correlated with a decrease in hippocampal subfield neuronal arborization and dendritic spines. These findings led us to conclude that exposure to CW MW radiation leads to oxidative/nitrosative stress induced p53-dependent/independent activation of hippocampal neuronal and nonneuronal apoptosis associated with spatial memory loss.
The present experiment was designed to study the  2.45 GHz low-level microwave irradiation-induced stress response (continuous wave exposure for 2h/day for 45 days) and its effect on implantation or pregnancy in female mice. Researchers observed that implantation sites were affected significantly in MW-irradiated mice as compared to control and in addition to a significant increase in ROS, hemoglobin, RBC and WBC counts, N/L ratio, DNA damage in brain cells, and plasma estradiol concentration, a significant decrease was observed in NO level and antioxidant enzyme activities of MW-exposed mice. Our findings led us to conclude that a low level of MW irradiation-induced oxidative stress not only suppresses implantation, but it may also lead to deformity of the embryo in case pregnancy continues. We also suggest that MW radiation-induced oxidative stress by increasing ROS production in the body may lead to DNA strand breakage in the brain cells and implantation failure/resorption or abnormal pregnancy in mice.
Things didn’t end well between George Carlo and Tom Wheeler; the last time the two met face-to-face, Wheeler had security guards escort Carlo off the premises. As president of the Cellular Telecommunications and Internet Association (CTIA), Wheeler was the wireless industry’s point man in Washington. Carlo was the scientist handpicked by Wheeler to defuse a public-relations crisis that threatened to strangle his infant industry in its crib. This was back in 1993, when there were only six cell-phone subscriptions for every 100 adults in the United States. But industry executives were looking forward to a booming future.1
“There are 25,000 brain tumor cases in India’s Andhra Pradesh and Telangana states, and most of them are attributed to excessive use of cell phones, as per a recent medical survey”. Girish Kumar said that World Health Organization warned of increasing risk of cell phone brain tumor and cancer cases caused by the use of cell phones and location of cell towers in residential areas.
