There is an opinion that, talking in the cellular, a person is subjected to harmful irradiation for health, and this can lead to the development of cancer. We decided to check if there are grounds for such fears.
Many media wrote about the fact that conversations on a mobile phone are provoked by cancer (for example, "Newspaper.ru","Kommersant","News" News.ru, "RIA Novosti") And others Information And Entertaining resources. There are similar statements on some medical Portals, where experts advise using the headset or headphones to reduce negative impact when calls. True, in other sources Approvedthat wireless headphones are not a panacea and also cause cancer. On the network you can find and publications The fact that dangerous radiation from smartphones proceeds constantly, and not just during a conversation, therefore, for example, for the prevention of cancer, they are advised not to put gadgets at night next to the bed.
In 2022, the UN International Union declaredthat 73% of the world's population use mobile phones, in Europe and the CIS - more than 90%. Because of this, it is quite difficult to find a correlation between the possession of cellular and oncological diseases with the use of scientific methods-to find a control group that has not been used by such devices for many years is almost impossible in the modern world. Cellular has acquired wide spread relatively recently, and if they really provoke the development of cancer, it would be logical to assume that the number of oncological patients should grow with the growth of their number. However, the National Institute of US Cancer claimsthat over the past decades, the average annual number of new diagnosed cases of brain cancer and other organs of the central nervous system remained at the same level.
The fears that mobile phones can cause cancer are due to the fact that these devices emit radiation. This is the principle of their work - they are reported among themselves, transmitting radio waves through the tower of communication. However, this is not at all about the radiation, at the mention of which many recall nuclear bombs or an accident at the Chernobyl nuclear power plant.
Radiation It is ionizing and non -ionizing. The first is really able to damage DNA molecules in the human body, which, in turn, can provoke cancer. Ionizing radiation includes, for example, x -rays or ultraviolet rays. Nononizing radiation is believed to cause DNA damage. To this type refers, for example, radiation from microwave ovens, computers, mobile phones and devices using WiFi and Bluetooth technologies.
World Health Organization (WHO), Disease control centers (CDC) and National Institute sciences of the environment of the USA, as well as International Commission In terms of protection against non -ionizing radiation, it is argued that today there is no scientific data that allows an affirmative answer to the question of whether the radiation of mobile phones can provoke the development of cancer. They agree with this and Experts The US National Center for US Cancer, which conducted the review of the highest quality studies in this area and also did not find any convincing results confirming that the radiation of a mobile phone can provoke cancer.
In 2018, experts of the US National toxicological Program Published The results of the experiment, during which laboratory rats and mice throughout life were exposed to radiation. It was similar to what is used in 2G and 3G cellular technologies. Scientists really have evidence that animals have a connection between the irradiation and development of malignant neoplasms of the heart, brain and adrenal glands. Nevertheless, researchers note that the impact on rats and mice during the experiment cannot be compared with the one that a person is subjected to using a mobile phone. Firstly, scientists irradiated the whole body of rodents, while in people only small areas of the body are exposed to radiation. Secondly, the minimum level of exposure to radiation on experimental rodents was equal to the maximum permissible in the United States, the effects of radiation from phone per person. The maximum level of influence on animals exceeded the permissible for people by four times. There was longer the time of exposure - about nine hours a day. Few people talk to the cell phone every day for so long.
The level of exposure to radiation from phone per person is determined by Specific absorption coefficient (SAR). This is a measure of the speed of absorption of radio frequency energy with a body from the measured source - in this case from the gadget. Manufacturers are required to carry out the appropriate tests, and in order for their products to get into stores, the maximum values of SAR should be lower than those that the supervisory authorities of a country are considered safe. In 2023, the National Frequency Agency of France Forbidden In the country of IPhone 12 sales due to exceeding the permissible indicator. Apple company She saidthat the smartphone really could emit somewhat more intense radiation, but only if he lay on a static surface and did not come into contact with the human body, and the agency simply did not take into account this nuance during testing. Nevertheless, the iPhone manufacturer has released the software update for French users, where this violation was eliminated.
It would be logical that worried buyers can choose devices with the lowest SAR indicators to reduce risks, but this indicator does not reflect the real picture. The fact is that only the maximum values of SAR are included in the documentation, which are observed in the most extreme operating conditions. With normal use, these indicators are different, and there are no guarantees that if one phone showed a lower SAR during tests than another, then with standard operation of its SAR will be lower.
International Cancer Research Agency classifies The impact of mobile phones on human health as “possible carcinogenic”, even though most of the scientific research has not revealed a direct relationship and many authoritative medical organizations deny it. However, almost all researchers agree that for an unambiguous answer to the question, whether radiation from a cell phone can cause cancer, extensive additional studies are needed, including in humans. Their conduct to a large extent complicated The fact that regular impact on people with large doses of radiation is impossible for ethical reasons, therefore, the main method is statistical, based on user self -reports. At the same time, the reliability of the information provided is difficult to establish, because people with and without and without cancer can differently evaluate the frequency and duration of using the phone, the diagnosis can distort their perception. In addition, brain tumors often negatively affect cognitive functions, which also complicates the survey of patients. Another difficulty in conducting research is that mobile phones are constantly being improved, including from the point of view of security, therefore, data on the impact that could exert the early 2000s, are no longer relevant for modern smartphones.
It is worth noting that most of the studies are devoted to the impact of radiation similar to what are used in the cellular connection of 2G and 3G types. A new generation cellular connection is being actively developing - 5G. Its influence on humans and animals in the long run has not yet been studied. The radiation, which is used for 5G, is more highly frequent, but it still refers to the non -ionizing type of radiation, which cannot destroy DNA. In addition, it is more difficult for high -frequency radio waves to pass through fabrics and objects, which means that there is reason to believe that the effects of 5G networks on the internal organs of a person are even less likely.
To maximize the risks of negative effects of radiation from cellular, CDC experts Consult Use the headset and ligament. The wireless Bluetooth Hobs also emit radio frequency waves, but their capacity is many times lower than that of mobile phones. Experts agree with this advice WHO, US National Center And American oncological society. In addition, it is worth it avoid calls with a weak network signal, as this leads to an increase in the capacity of radio frequency radiation of cell phones.
Excessive use of smartphones can be dangerous to health and exclusively radiation. For example, a huge amount settles on the apparatus microbes, since people use devices almost everywhere - from public transport to the toilet, and disinfect them much less often than they wash their hands. Therefore, probably, to bring gadgets to the face once again is not the most successful idea. However, the same applies to Naushnikov - If they are not regularly disinfected, you can bring an infection into the ears. In addition, in 2017, Korean scientists Spent Magnetic resonance spectroscopy (a type of study that helps to find out the chemical composition of the brain) of 19 young people with diagnosed dependence on smartphones and the Internet, as well as 19 healthy peers. It turned out that an excessive enthusiasm for a mobile phone, apparently, causes chemical changes in the work of the brain, which increases the likelihood of developing depression, anxiety and insomnia. And this is far from the whole list problems, to which the abuse of a mobile phone can lead.
Thus, almost all authoritative medical organizations agree that, despite the years of research, today there is no convincing scientific evidence that radiation from mobile phones can provoke oncological diseases. Firstly, the frequency at which they transmit data is too low and is unable to destroy human DNA molecules (which causes cancer development). Secondly, supervisory authorities of different countries establish a safe level of radiation, and all devices entering sale must correspond to it. Therefore, it does not matter how many percentage of charging the phone remains, whether it is connected to the charging device or how good is the signal of communication - the radiation should not exceed the permissible safe limit, otherwise such a device would not receive permits or would be removed from the sale. Nevertheless, it is always possible to additionally reduce the risks by talking on the phone by speakerphone or through headphones (even wireless, because radiation from them is still much weaker than from the phone).
