5G network rely on signal carried by radio waves- part of the electromagnetic spectrum- transmitted between the antenna or mast and your phone, just like any other previous cellular technologies.
You should understand that we are all surrounded by electromagnetic radiation every time- from the sunlight, television, radio transmission, mobile phones and as well as technologies. 5G network has higher frequency waves than the previous Mobil network (4G and 3G) with ability to travel faster in a short distance. Hence, 5G network require more transmitter mast than previous technologies.
Many believed that the electromagnetic radiation from 5 Generation networks are carcinogenic, and therefore, can lead to cancer. And the waves are mutagenic- has the capability to change the DNA structure of living beings.
Some scientist believed that 5G mast and mini-station are dangerous and hazardous to human beings, not just because of shorter millimeter waves but also high intensity of the technology. Therefore, it will require more of mini-cell within short distance, potentially one tower per 5 to 15 houses. Simply means human beings will be sporadically exposed to radiation.
This misconception led scientists to more Research in order to confirm the consequences of this technology.
Prof. Rodney Croft, an adviser to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) was against this affirmation based on tested work and were the network are functioning such as United Kingdom that, "the heat effects are not harmful, the maximum radio frequency level that someone in the community could be exposed to is so small that no temperature rise has been observed to date."
In 2014, World Health Organization (WHO) said that "no adverse health effects have been caused by mobile phone users".
For 5G (fifth generation) network radiation to be considered dangerous to human health, it needs to be ionizing which 5G is not.
Therefore, 5 G network can not result to cancel, though it has been proven that exposure to radiation can cause cancer, miscarriage, leukemia, Weak sperm to mention a few but the radiation of 5G is very small.
