5G technology uses higher frequencies to make a difference in data transfer capabilities, but many people fear it could affect health. So far, the world still believes that 5G technology is not harmful to health. However, that hasn’t convinced everyone. A petition with 29,000 signatures was sent to the British parliament calling for an independent investigation of the health and safety risks of the next generation of mobile phones. The government has rejected the request, but the people of England and the world want to know if electromagnetic radiation is harmful to the body. Why is 5G causing fear? To understand if 5G is dangerous, we need to understand what its nature is. First, look at the diagram of the electromagnetic spectrum, including all possible frequency bands of electromagnetic radiation (or electromagnetic waves). Electromagnetic radiation is classified as radio waves, microwaves, terahertz radiation (or below mm), infrared (infrared), visible light, and ultraviolet rays. (ultraviolet), X-rays (gamma waves) and gamma rays (gamma waves). Among these, people are divided into 2 main categories: – Ionizing radiation (Ionizing), such as X-rays or gamma rays, with high frequencies can enter the body to harm cells. They have enough energy to cause ionization of atoms. – Non-ionizing radiation, such as radio waves, visible light or infrared radiation, is not capable of destroying atoms. Non-ionizing radiation cannot reach the human body, only making the surface molecule vibrate faster. Electromagnetic radiation (or electromagnetic waves) is measured by frequency and wavelength. Radiations at lower frequencies and longer wavelengths than visible light include radio waves and microwaves. Mobile phone waves are in this spectrum, including 5G. They belong to the group of non-ionizing radiation, because there is not enough energy to break down the molecular bonds. Non-ionizing radiation absolutely safe? While non-ionizing radiation is weaker than ionization, it is thought that it is still capable of altering the body. Many people misunderstand this type of radiation can cause cancer like ionizing radiation. Britain’s National Health Service (NHS) said there has been a great deal of scientific research on the health effects of mobile phone use since the 1990s. But no studies have demonstrated radiation. Cell phone harmful as the form of ion radiation. Some people think that high frequencies of 5G will affect the brain, but this is not true because they are within the threshold. Only when the frequency exceeds the visible light is it harmful, like ultraviolet rays, X-rays or gamma rays. What happens when radio waves hit the body? When radio waves hit the human body, they are absorbed by simple and absorbed tissues into energy. Scientific research has not shown radio waves alter the molecular structure of any type of tissue. They have the ability to increase the temperature of cells by 0.2 degrees Celsius, which is equivalent to a natural increase in exercise, not considered a health risk. “Major studies have no evidence that mobile radio waves cause health problems,” the NHS said in reassuring public opinion. So is radio waves really harmful? So far, studies have not concluded that radio waves are harmful to human health. The Cancer Research Organization of the United Kingdom notes that, although mobile phone ownership rates increased by about 500% between 1990 and 2016, the incidence of brain cancer increased by only 34%. In 2011, the International Agency for Research on Cancer placed mobile phones as a “cause of cancer”. But it is only based on scientific reports, not considered final conclusions. Certainly, non-ionizing radiation, including 5G waves, is unlikely to cause cancer directly.
