The wireless industry has sought to downplay concerns about cell phones’ safety, and the Federal Communications Commission has followed its example. In 1996, the FCC established cell-phone safety levels based on “specific absorption rate,” or SAR. Phones were required to have a SAR of 1.6 watts or less per kilogram of body weight. In 2013, the American Academy of Pediatrics advised the FCC that its guidelines “do not account for the unique vulnerability and use patterns specific to pregnant women and children.” Nevertheless, the FCC has declined to update its standards.30

when i bring my hand very close to a tuned-in radio transistor, the volume drops to almost zero and i can no longer hear the music or news unless i take my hand away from the transistor radio set. if that is the effect of em radiations from a human body on the audible signal of an electronic device reducing its audio signal to almost zero then the long-term effect of powerful em radiation of 1- 2GH frequency from a wi-fi router or a celphone must be dramatically traumatic for the human health. this has to be so because human body almost entirely functions on signals generated by ions and molecules in the body cells which are likely to be severely disrupted in the presence of such strong em radiation fields emitted by man-made external sources such as wi-fi routers and mobile phones.

Numerous peer-reviewed studies have found that cell phone use is not associated with an increased risk of brain tumors. An Oct. 20, 2011 study of 358,403 Danish citizens – the largest study of its kind to date – concluded that "there was no association between tumors of the central nervous system or brain and long term (10 years +) use of mobile phones." [39] A July 27, 2011 study found that there was no association between cell phone use and brain tumor risks among children and adolescents. [50] Numerous other studies published from 2001-2013 have similarly concluded that there is no association between cell phone use and the development of brain tumors. [1] [41] [42] [45] [46] [49]
Irradiation was performed during three weeks, after which plants were removed from the chambers for measurements of volatile organic compound (VOC) emission and analyses of leaf structure and essential oil content. All measurements of VOC emission and analyses of leaf structure and essential oil content have been replicated with eight different plants.
Cell phone radiation may disrupt the functioning of pacemakers. A 2005 study in the International Journal of Cardiology found that mobile phones may have "adverse effects" on pacemaker functions under certain conditions. [59] According to the US Food and Drug Administration (FDA), radiofrequency energy from cell phones can create electromagnetic interference (EMI) that may disrupt the functioning of pacemakers, especially if the cell phone is placed close to the heart. [21] The American Heart Association includes cell phones on its list of "devices that may interfere with pacemakers." [60]
Years later, a study that Leszczynski described as a “game changer” discovered that even phones meeting government standards, which in Europe were a SAR of 2.0 watts per kilogram, could deliver exponentially higher peak radiation levels to certain skin and blood cells. (SAR levels reached a staggering 40 watts per kilogram—20 times higher than officially permitted.) In other words, the official safety levels masked dramatically higher exposures in hot spots, but industry-funded scientists obstructed research on the health impacts.45
CONCLUSION: The available literature on the effect of RF-EMFs on plants to date observed the significant trend of radiofrequency radiation influence on plants. Hence, this study provides new evidence supporting our hypothesis. Nonetheless, this endorses the need for more experiments to observe the effects of RF-EMFs, especially for the longer exposure durations, using the whole organisms. The above observation agrees with our earlier study, in that it supported that it is not a well-grounded method to characterize biological effects without considering the exposure duration. Nevertheless, none of these findings can be directly associated with human; however, on the other hand, this cannot be excluded, as it can impact the human welfare and health, either directly or indirectly, due to their complexity and varied effects (calcium metabolism, stress proteins, etc.). This study should be useful as a reference for researchers conducting epidemiological studies and the long-term experiments, using whole organisms, to observe the effects of RF-EMFs.
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 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).
Several studies that will provide more information are under way. Researchers from the Centre for Research in Environmental Epidemiology in Spain are conducting another international case–control study—Mobi-Kids—that will include 2000 young people (aged 10–24 years) with newly diagnosed brain tumors and 4000 healthy young people. The goal of the study is to learn more about risk factors for childhood brain tumors.
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.

“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.
