The energy of electromagnetic radiation is determined by its frequency; ionizing radiation is high frequency, and therefore high energy, whereas non-ionizing radiation is low frequency, and therefore low energy. The NCI fact sheet Electromagnetic Fields and Cancer lists sources of radiofrequency radiation. More information about ionizing radiation can be found on the Radiation page.
People who say cell phones are safe reference statements by the FCC and Food and Drug Administration (FDA) and point to peer-reviewed studies which conclude that cell phone use is not associated with an increased risk of brain tumors or the onset of other health problems. They contend there has been no increase in brain tumor rates despite hundreds of millions of people now using cell phones.
In certain situations, it's necessary to use your cell phone when your hands are otherwise occupied. For those times, a Bluetooth headset comes in handy. These lightweight headsets attach above one or both of your ears or around your neck, and allow you to talk without having to do so directly into your phone. These are rechargeable devices that offer around eight hours of talk time. You can also listen to music and use GPS applications and many other apps that your phone has. Bluetooth headsets are compatible with most or all Bluetooth-enabled mobile devices.

Keep it locked. “Make sure that you have a secret PIN (personal identification number), a password, fingerprint setting or other security measures in place so that only you can access your phone.” – National Cyber Security Alliance, June is Internet Safety Month!

This study measured the levels of blood lipid peroxidation, glutathione peroxidase, reduced glutathione, and vitamin C to follow the level of oxidative damage caused by 2.45 GHz electromagnetic radiation exposure (60 min/day for 28 days) in rats. The possible protective effects of selenium and L-carnitine were also tested and compared to untreated controls.  Researchers found that 2.45 GHz electromagnetic radiation caused oxidative stress in blood of rat. L-carnitine seems to have protective effects on the 2.45-GHz-induced blood toxicity by inhibiting free radical supporting antioxidant redox system although selenium has no effect on the investigated values.
This study used Drosophila as model organisms to assess the effects of various EMF sources (short time daily for 3-7 days) on apoptotic cell death of follicles during oogenesis and reproductive capacity (fecundity) decline. Sources included: 900/1800 MHz mobile phone, 1880-1900 MHz wireless base, wireless handset, mobile phone-handset combination, 2.44 GHz wireless network (Wi-Fi), 2.44 GHz bluetooth, 92.8 MHz FM generator, 27.15 MHz baby monitor, 900 MHz CW RF generator and microwave oven’s 2.44 GHz RF and magnetic field components. All EMF sources used created statistically significant effects regarding fecundity and cell death-apoptosis induction, even at very low intensity levels well below ICNIRP’s guidelines, suggesting that Drosophila oogenesis system is suitable to be used as a biomarker for exploring potential EMF bioactivity.
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.
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.
It’s been suggested that sleeping near a phone, in a home with Wi-Fi, or in an apartment building with many Wi-Fi signals can create chronic sleep problems as the constant bombardment of Wi-Fi pollution interferes with falling asleep and sleep patterns. For many, sleep deprivation is just the start for larger problems. The development of depression and hypertension have also been linked to inadequate sleep. [3]
And, it’s not just sperm. The results of an animal study suggest that some wireless frequencies may prevent egg implantation. During the study, mice exposed 2 hours a day for 45 days had significantly increased oxidative stress levels. The cellular damage and impact on DNA structure from exposure suggest a strong possibility of abnormal pregnancy or failure of the egg to implant. [12]
Because these are complex diseases that develop over decades, it is difficult to conclusively show that the increase in wireless signal exposures directly cause the diseases. International Agency for Research on Cancer (IARC) considers wireless radiation as a class 2B possible carcinogen due to limited evidence. These small number of studies are leaning towards showing that electromagnetic radiations, including WiFi, are not safe.
What the study showed: Self-reported cell phone use was not associated with an increased risk of glioma, meningioma, or non-central nervous system tumors. Although the original published findings reported an association with an increased risk of acoustic neuroma (14), this association disappeared after additional years of follow-up of the cohort (15).
1. Be careful what you share. “Use the same good sense about what you post from your phone as from a computer. Once they’re posted, text, photos, and video are tough to take back, can be copied and pasted elsewhere, and are up there pretty much forever. Think about the people in them (including you!). Reputations are at stake.” – Tips for Smart Cellphone Use, Connect Safely; Twitter: @ConnectSafely
