The 5G mobile network is included in some UK cities and has raised questions as to whether the new technology poses health risks .
What's the difference in 5G?
As with previous cell technologies, 5G networks rely on signals transmitted by radio waves ̵
We are constantly surrounded by electromagnetic radiation – from television and radio signals, as well as a whole range of technologies, including mobile phones, and from natural sources such as
5G using waves at a higher frequency than the earlier mobile networks, allowing more devices to access the Internet at the same time and at faster speeds. 5G networks require more transmitter masts than previous technologies located closer to ground level.
What are the worries?
Electromagnetic radiation used by all mobile phone technology has led some people to worry about increased health risks, including the development of some types of cancer.
In 2014, the World Health Organization (WHO) said that "no adverse health effects caused by the use of mobile phones have been identified".
However, the WHO, together with the International Agency for Research on Cancer (IARC), has classified all radiofrequencies (of which the mobile signals are
). It is included in this category because "there is evidence that it is not convincing, that exposure can cause cancer in humans. "
Eating marinated vegetables and using talc are:
Alcoholic beverages and processed meat are classified as a higher risk.An toxicology report published in 2018 by the Ministry of US healthcare and indicated by those who, it was found that male rats exposed to high doses of radio frequency radiation developed a type of cancerous tumor in the heart
For this study, the whole rat body was exposed to radiation from mobile phones for nine hours a day each day for two years starting before they were born.
No cancer was detected for female rats or mice. studied. It was also found that rats exposed to radiation lived longer than those in the control group.
A senior scientist in the study says "exposures used in surveys can not be compared directly with the exposure people are experiencing when using a cell phone," even for heavy users.
Dr. Frank De Wohl, who helps the government to inform the government about the safety of mobile phones, says that "although some of the studies suggest a statistical possibility of an increased risk of cancer for heavy users, evidence of a causal link are not convincing enough to suggest the need for safeguards. "
However, there is a group of scientists and doctors who have written to the EU calling for a 5G suspension
Radio waves are not ionizing
Radio wave tape – used for cellular networks – does not ionize, "meaning it lacks enough energy to break the DNA and cause cellular damage," said David Robert Grimms, a physicist and cancer.
Higher than the electromagnetic spectrum, far above those frequencies used by mobile phones, there are clear health risks from prolonged exposure
Solar ultraviolet rays fall into this harmful category and can lead to skin cancer.
There are strict limits to exposure to even higher levels of energy radiation, such as medical X-rays and gamma rays, which can both cause harmful effects in the human body. "People are understandably concerned about whether they can increase the risk of cancer, but it is crucial to note that radio waves are far less vigorous than even the visible light we experience every day," says Dr. Grimes.
"There is no respectable evidence," he says, "that mobile phones or wireless networks have caused us health problems."
Do we need to worry about 5G masts on the transmitter? – these are masts that transmit and receive signals from mobile phones.
But most importantly, since there are more transmitters, each one can operate at lower power levels than the previous 4G technology, which means that the radiation level of 5G antennas will be lower. Base stations say that radio frequency fields in places that are generally available to the public are many times lower than recommended levels
Part of the 5G spectrum, licensed under international guidelines, falls into the microwave band. generate heat in objects through which they pass.
However, at the levels used for 5G (and earlier mobile technologies), the thermal effects are not harmful, says Professor Rodney Croft, counselor of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). the maximum level of radio frequency that anyone in the community could be exposed to from 5G (or other signals in common areas) is so small that no increase in temperature has been observed so far. Exposure Limitations  The UK Government says that "although a small increase in total exposure to radio waves is possible when 5G is added to the existing network, overall exposure is expected to remain low."
Frequency range of the input 5G signals is within the non-ionizing band of the electromagnetic spectrum and is much lower than what is considered harmful by ICNIRP.ICNIRP, with the constraints placed well below the lowest level of 5G bandwidth for which has been shown to cause harm, says Professor Croft, have some health effects
