The study was an attempt to draw attention towards the adverse effects of non-ionizing electromagnetic radiations (NI-EMR) in the frequency that is used widely in the field of telecommunication. Many studies have captured the impact of the 900 MHz and 1800 MHz frequencies, however the frequency of radiation in Wi-Fi range has not been much explored. Along with the use of cell phones there is a growing concern with the use of Wi-Fi devices which continuously emit radiations in the frequency of 2.4 GHz. Hence we thought it prudent to investigate the impact of radiation of the frequency of 2.45 GHz. It can be concluded that the exposure to non-ionizing radiation of 2.45 GHz caused detrimental changes in rat brain leading to learning and memory decline and expression of anxiety behavior along with fall in brain antioxidants. The exposure triggered the gene expression of caspase 3 which plays a major role in the apoptotic pathway. The chronic impact of non-ionizing radiation needs to be thoroughly evaluated in humans so that combative steps can be taken.
There is an alternative approach, rooted in what some scientists and ethicists call the “precautionary principle,” which holds that society doesn’t need absolute proof of hazard to place limits on a given technology. If the evidence is sufficiently solid and the risks sufficiently great, the precautionary principle calls for delaying the deployment of that technology until further research clarifies its impacts. The scientists’ petition discussed earlier urges government regulators to apply the precautionary principle to 5G technology. Current safety guidelines “protect industry—not health,” contends the petition, which “recommend[s] a moratorium on the roll-out of [5G]…until potential hazards for human health and the environment have been fully investigated by scientists independent from industry.”54
Cell phone storage in front pockets has been linked to poor fertility and higher chances of miscarriage and childhood cancer.  According to the Cleveland Clinic Center for Reproductive Medicine, semen quality "tended to decline as daily cell phone use increased."  According to a May-June 2012 meta-study in the Journal of Andrology, "men using mobile phones have decreased sperm concentration" in addition to "decreased viability" of their sperm. 
Long-term exposure to Radio Frequency waves or microwave radiation has long been studied and shown to produce all sorts of adverse health effects. See my post on EMF Radiation Exposure Symptoms for a full list of common symptoms. Even the American Cancer Society, who in large part will not fully say that EMF radiation causes long-term harm, and instead errs on the side of not enough research, admits on their website, that:
4. For the reasons mentioned in #3 above, an at-home meter test is extremely inaccurate and unreliable. That said, a far field RF meter such as the one you are using is highly influenced by ambient RF levels that exist almost everywhere. Again, we do not aim to eliminate the radiation from the device, nor from your surroundings, but our technology does deflect the radiation away from the body.
We asked Dr. George Carlo his thoughts on EMF cases and shielding products, “most offer some protection, some of the time, to some people, because they can alter the immediate electromagnetic field environment around the person,” and immediately emphasizes the importance of “some,” which seems to tell us that it’s vastly unpredictable. “All waveforms in the environment are highly variable and they interact with other factors in the environment that make them even more variable.” This pretty much sums up that the artificial electromagnetic energy universe is vastly unpredictable.
An analysis of data from all 13 countries participating in the Interphone study reported a statistically significant association between intracranial distribution of tumors within the brain and self-reported location of the phone (7). However, the authors of this study noted that it is not possible to draw firm conclusions about cause and effect based on their findings.
The present study examined the biological effects of continuous wave 2.45 GHz microwave radiation (2h/day for 30 days) in Parkes strain mice. The results show that microwave radiation caused an increase in erythrocyte and leukocyte counts, a significant DNA strand break in brain cells and the loss of spatial memory in mice. This report for the first time provides experimental evidence that continuous exposure to low intensity microwave radiation may have an adverse effect on the brain function by altering circadian system and rate of DNA damage.
The wireless industry’s determination to bring about the Internet of Things, despite the massive increase in radiation exposure this would unleash, raises the stakes exponentially. Because 5G radiation can only travel short distances, antennas roughly the size of a pizza box will have to be installed approximately every 250 feet to ensure connectivity. “Industry is going to need hundreds of thousands, maybe millions, of new antenna sites in the United States alone,” said Moskowitz, the UC Berkeley researcher. “So people will be bathed in a smog of radiation 24/7.”53
Our studies point that WIFI is not completely safe at home near the animal or human body because it employ harmful radio waves. But it is safer compared to cellphone that it is close to our brain during communications. WIFI signals are everywhere. If you switched off your WiFi at night, you are still exposed to the WIFI signals coming in from neighbors but we have a significant reduction of the bioeffects of WIFI with distance from the router. Future investigations will focus on the long term bioeffects of WIFI placed at an important distance from the animal or the human.
RESULTS: Our analysis demonstrates that the data from a substantial amount of the studies on RF-EMFs from mobile phones show physiological and/or morphological effects (89.9%, p < 0.001). Additionally, our analysis of the results from these reported studies demonstrates that the maize, roselle, pea, fenugreek, duckweeds, tomato, onions and mungbean plants seem to be very sensitive to RF-EMFs. Our findings also suggest that plants seem to be more responsive to certain frequencies, especially the frequencies between (i) 800 and 1500 MHz (p < 0.0001), (ii) 1500 and 2400 MHz (p < 0.0001) and (iii) 3500 and 8000 MHz (p = 0.0161).
In a separate study by the same Swedish team, they found more than seven times the risk among people using a cell phone more than 20 years and 6.5 times the risk for long-term users of cordless phones. As expected, most of the gliomas and acoustic neuromas were on the same side of the head, which was usually exposed to the phone. In the 2013 official report on the medical evidence for brain tumors, the International Agency for Research on Cancer concluded that radiation from cell phones is “possibly carcinogenic to humans”.
