Conclusion. The long term exposure to 900-1800 MHz frequency radiations emitted from 2G mobile phone could cause significantly reduced neuron density and decreased nuclear diameter in the hippocampus neurons of mice.
Also, how much MHz is dangerous?
The most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the human body absorbs RF energy most efficiently when the whole body is exposed.
Also Know, is 4g harmful to health? To date, no adverse health effects have been established as being caused by mobile phone use." International guidelines on exposure levels to microwave frequency EMFs such as ICNIRP limit the power levels of wireless devices and it is uncommon for wireless devices to exceed the guidelines.
Subsequently, one may also ask, is WiFi damaging to health?
Repeated Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload.
Is WiFi an EMF?
Wireless networks stream invisible radio waves, a form of radiofrequency radiation (EMFs), through the air — similar to cellphones, computers, Bluetooth speakers, and other WiFi-powered devices. Non-ionizing EMF is low-level radiation which is generally viewed as harmless.
