The FCC sets the maximum amount of thermal radiation (heat) that cell phones are permitted to emit.  This limit is measured as the amount of radiation absorbed by a user and is known as the specific absorption rate (SAR). In 1996 the SAR for cell phone radiation was set at a maximum of 1.6 watts of energy absorbed per kilogram of body weight. Manufactures of cell phones must test their products to ensure that they meet this standard. Random tests of phones on the market by FCC scientists further ensure that radiation levels meet FCC guidelines. 
Of course, trying to avoid radio wave exposure is more or less impossible if you live in modern society. Moskowitz advises keeping wireless devices away from your body and turning off wireless networks when they’re not in use. While any health risks are still theoretical, “I think trying to minimize exposure is the best advice at this point,” Moskowitz adds.

Listeria monocytogenes response to each antibiotic was different, for DOX (doxycycline), and the window response occurred after 6 hours of exposure to Wi-Fi and RF simulator radiation. However, for other antibiotics, these changes were only observed at the ninth hour of exposure to Wi-Fi while this response could not be observed for RF simulator radiation. After 9 hours of exposure to Wi-Fi for CIPR and SXT antibiotics, bacteria had a tendency to become more resistant. This was in contrast to the pattern observed for LEVO, CTX, and CTR antibiotics, which an increased sensitivity was observed.
This investigation concerns with the effect of low intensity microwave (2.45 and 16.5 GHz, SAR 1.0 and 2.01 W/kg, respectively) radiation on developing rat brain when exposed for 35 days. Results showed that the chronic exposure to these radiations caused statistically significant (p<0.001) increase in DNA single strand breaks in brain cells of rat.
According to an anonymous questionnaire, daily active cell phone usage was divided into three groups as following: Group A, < 30 min/d; Group B, from 30 min/d to 2 h/d; and Group C, > 2 h/d. Habits of carrying a mobile phone was recorded as (A) in the pocket of trousers, (B) in a handbag, or (C) in the pocket of jackets. Wireless internet usage was divided in to three groups, Group A: < 30 min/d; Group B, from 30 min/d to 2 h/d; and Group C, > 2 h/d. Internet usage types recorded as wireless or not.
The aim of this study was to investigate the effects of prenatal and postnatal 2450 MHz electromagnetic field exposure (1hy/day from intrauterine or postnatal period) on the growth and development of female Wistar rats. Birth masses of the groups were similar (p > 0.05), however mass gain per day was significantly lower and the puberty was significantly later in the prenatal group. Brain and ovary TOS and OSI values in the prenatal group were significantly increased (p < 0.05) compared to the control group and serum LH levels of the prenatal and postnatal groups were increased, although serum FSH, and E2 values did not differ among the groups (p > 0.05). Histological examinations of the specimens revealed no statistically significant difference between the groups (p > 0.05). Exposure to 2450 MHz EMF, particularly in the prenatal period, resulted in postnatal growth restriction and delayed puberty in female Wistar rats. Increased TOS and OSI values in the brain and ovary tissues can be interpreted as a sign of chronic stress induced by EMF.
While cell phones localize the highest microwave exposure to the brain, Wi-Fi exposures are often localized to the abdomen, leg and chest area. However this is not always the case as some people sleep in rooms with Wi-Fi baby monitors, Wi-Fi routers or Wi-Fi gaming devices near their pillow. Wi-Fi printers may be in offices next to a person’s desk and most people are unaware that they transmit continuously. All in all, for some people- especially children- the Wi-Fi exposure is quite significant to overall cumulative exposure.
We aimed to investigate the effects of distance from sources on calcium signaling, cytosolic ROS production, cell viability, apoptosis, plus caspase-3 and -9 values induced by mobile phones and Wi-Fi in breast cancer cells. The cytosolic ROS production, Ca2+ concentrations, apoptosis, caspase-3 and caspase-9 values were higher in groups exposed to 900 MHz, 1800 MHz and 2450 MHz compared to controls at 0 cm, 1 cm and 5 cm distances although cell viability (MTT) values were increased by the distances. There was no statistically significant difference in the values between control, 20 and 25 cm. Wi-Fi and mobile phone EMR placed within 10 cm of the cells induced excessive oxidative responses and apoptosis via TRPV1-induced cytosolic Ca2+ accumulation in the cancer cells. Using cell phones and Wi-Fi sources which are farther away than 10 cm may provide useful protection against oxidative stress, apoptosis and overload of intracellular Ca2+.
Remarkably, cell phones had been allowed onto the US consumer market a decade earlier without any government safety testing. Now, some customers and industry workers were being diagnosed with cancer. In January 1993, David Reynard sued the NEC America Company, claiming that his wife’s NEC phone caused her lethal brain tumor. After Reynard appeared on national TV, the story went viral. A congressional subcommittee announced an investigation; investors began dumping their cell-phone stocks; and Wheeler and the CTIA swung into action.2
We aimed to investigate the protective effects of melatonin and 2.45 GHz electromagnetic radiation (60 min/day for 30 days) on brain and dorsal root ganglion (DRG) neuron antioxidant redox system, Ca(2+) influx, cell viability and electroencephalography (EEG) records in the rat. Lipid peroxidation (LP), cell viability and cytosolic Ca(2+) values in DRG neurons were higher in EMR-exposed groups than in controls, although their concentrations were increased by melatonin, 2-aminoethyldiphenyl borinate (2-APB), diltiazem and verapamil supplementation. Lower numbers of EEG spikes were recorded in EMR+melatonin groups than in EMR only, while brain cortex vitamin E concentrations were higher in the melatonin-supplemented group. In conclusion, Melatonin supplementation in DRG neurons and brain seems to have protective effects on the 2.45 GHz-induced increase Ca(2+) influx, EEG records and cell viability of the hormone through TRPM2 and voltage gated Ca(2+) channels.
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.
BACKGROUND: Dental amalgam is composed of approximately 50% elemental mercury. Despite concerns over the toxicity of mercury, amalgam is still the most widely used restorative material. Wi-Fi is a rapidly using local area wireless computer networking technology. To the best of our knowledge, this is the first study that evaluates the effect of exposure to Wi-Fi signals on mercury release from amalgam restorations.
The animals were exposed to an access point (AP) from WIFI device (D-Link DWL-3200 AP with 802.11 g mode and WPA2 network protection) as previously described in Salah et al. (2013). WIFI integrated two omnidirectional antennas that were setup for internet broadcast via wireless at 2.45 GHz. The sham control rabbits were placed under the same condition without applying RF (0 Hz). Antennas of WIFI were placed at 25 cm at the right side near the heart (animal in dorsal decubitus).
We really do not recommend any kind of chip, guard, anti-radiation "filters" or incomplete shielding case because honestly, how could they NOT provide a false sense of security? Folks could believe these products make them “invincible” against radiation so they are comfortable holding the case right up to their heads-and the radiation seeping from the back and the side of the phone case is in very close proximity to their precious brains. Oh no!
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.
