The opening of the seminar was in charge of the Cro.Ing. Guillermo Defays, director of the IPEI Institute of CePETel and Secretary of Occupational Health of the CTA of the Federal Capital, who thanked those present and emphasized the action of CePETel in the care of the health of colleagues. He highlighted the application of the Precautionary Principle in matters of occupational health and the Working Conditions and Environment. Next, Eng. José Bravo spoke about “Radio frequency radiation from mobile phones and its possible effects on Health”. Based on his exhaustive research, he mentioned the importance of creating awareness in the use of these Technologies to prevent the effects of radiation on people's health. Among the most important issues that stood out was that mobile technology is used massively by companies, workers, the government and also in the personal sphere, being that it provides enormous tools and profits. This brings us closer to the global level, that of 7600 million people, 60% use mobile devices. Some use more than one. The question that immediately arises from this is that innumerable numbers of human beings are subject to a problem: what is the limit to which the human body tolerates radiation from multiple sources such as a cell phone used close to the ear? And the answer is that although we are not prepared to detect the power level of electromagnetic radiation, the cells of the body respond.

The received power is related to the distance to the stations that emit the signal and to the emitted power. The energy is calculated by multiplying by the exposure time. There are also studies that indicate the distance a person must position himself to reduce risks and whose exposure time also influences human health.

The radiation power, of a mobile phone for example, will undergo different types of absorption depending on the matter in question. Be it cement, wood or human cells. This power will also depend on the efficiency of the mobile device; increasing power to compensate for ambient noise; of the attenuation of the signal by rain or by the place where the person is. As a personal precautionary measure, the key is not to use more power than necessary.

The device "is blind" because it does not know where the nearest base is located and when turning on, dialing or sending a text message, the mobile will transmit the required power in all directions. The transmitted power decreases the shorter the distance from the device to the base. When the person uses a device in an elevator or in a subway, the worst that can happen is that the communication is not cut off, because in these metallic environments, which are called "Faraday cages" and that although they were not totally closed spaces, the phone increases its power to compensate for the shielding effect. (See page 8 of the presentation on P.P.)

In conclusion, the first recommendation is that in areas with poor coverage, the cell phone should be kept away from the head area. Don't make voice calls. If the call is extremely necessary, let it last as short a time as possible or use the “hands-free”. In a normal coverage environment, power decreases as the person moves away from a mobile device. Therefore, it is recommended not to rest the phone to your ear, but to hold it 4cm from it. The best option is to use the hands-free service for calls or choose to use text messages.

Today, the hands-free service does not work optimally. While the headset normally works, it doesn't sound clean to the one on the other end of the phone. In the future, the devices should be differentiated in favor of how much better it is heard with the "hands free".

The research shows that, on the one hand, there are studies on radiation levels that occur in Nature and, on the other, the power levels with which it is implemented in the manufacture of electronic devices.

In Nature, the measure of constant radiation it receives from the sun and the stars is 0.0000000001 Microwatts per square centimeter (1 × 10-10? W / cm2). This measurement is exactly equal to the level of sensitivity of the human being as detected in the activity of the cells. The power density levels of mobile phones are billions of times higher than the natural level of radio frequency power density. twenty-one)

According to Physics, when the propagation of energy occurs in space, the result is dispersion. But when propagation occurs in matter, the result is the absorption of that energy. The matter that absorbs the energy of radiation when we speak on the phone is the brain.

So when energy travels in the air, there is scattering but when the radiation reaches a person's body, there is absorption. When we make mobile calls, the probability that the path of the energy to the cellular base passes through the head is 50%. Half of the power is directed to one side of the device and the other half is absorbed by the head (see page 22). However, we cannot perceive with our senses how much radiation energy we receive.

On the other hand, power is directly proportional to conductivity. The higher the conductivity, the higher the absorption of radiation energy. Conductivity in cerebrospinal fluid is greater than that of blood and brain tissues. The insulator in our system is fat. Fat is the most absorbent tissue in the human body. 35)

In turn, the accumulated radiation in the time that each person receives is accumulative year after year. The younger we start using cell phones, the more radiation we accumulate. In daily life, we are exposed to a large amount of radiofrequency radiation such as that which comes from WIFI, radio broadcasting antennas, microwaves, or cordless telephones whose base transmits radiation 24 hours a day, etc. The body is not prepared to receive so much radiation.

The organism has different defense mechanisms in its DNA, certain ways of organizing itself to what is known to it and reacts to what is foreign to nature. Some of the effects of radiofrequency radiation on people's health has to do with the cells in their DNA not being prepared to receive it because basically they are not in nature. Biological effects can lead to damage to health, which depend on the strength of its exposure, its duration, the accumulated total of exposure over time, the particular conditions of the person, etc. 53)

In turn, the absorption of radiation energy suffered by the brain of a child under 10 years of age, is greater per unit of mass than the brain of an adult, because the child has greater proportionality of fluid, blood and their tissues are more soft. 30)

What is alarming is that it is proven that radio frequency electromagnetic fields are carcinogenic to living beings. This is stated in the WHO studies from 2011 but, in turn, it is said that no causal link was found between the use of mobile phones and cancer. Then, on the one hand, statements of carcinogenic effects were published and, on the other hand, they did not affirm them because the methods used to determine such probability were considered inadequate or insufficient. On the other hand, there are multiple sources of radiation to which we are exposed, and that radiation from mobile technology is not ionizing, it is still dangerous.

In 1984, when mobile telephony began to appear in the US, the risks were unknown. Problems arise with radars in the "Second World War" and on high voltage lines, in which health risks are detected. At that time, scientists warned of the risks and the industry became interested in creating a research center whose results of these studies were only revealed in 1993 and 1994, proving the negative effects on people's health. The industry, contrary to trying to implement corrective measures for the prevention of users' health, paradoxically during the nineties, decided to suspend research and funding for this institution.

Subsequently, the IIEE (Institute of Electrical and Electronic Engineers of the United States) stipulates standards for safe levels of exposure to radiation from electromagnetic fields. The IIEE standards adopted by the US telecommunications regulatory agency are more restrictive than those in Europe. There are controlled environments depending on what the specialists act, but it was not convenient to regulate all types of environments like the usual ones: home or work.

In addition, the standards should set the Specific Absorption Rate (SAR), but in reality, even these standards allow higher levels than is tolerable. The tests to establish these norms are carried out by simulating the tissue of the brain and the human body with a substance formed from a specific liquid, with water and salt (see page 45). This simple study does not take into account the various tissues that exist in the human brain. It is not just a matter of measuring how much absorption occurs in a cell, but also how a certain amount of radiation affects each type of cell. 47)

So the measurements are far from reality. In practice, no rules are used. They do not apply. They are driven by convenience. Added to this is that the concept of radiation energy is difficult for an ordinary citizen to understand and measure.

It is not even known whether these standards are taken into account at the manufacturing stage of mobile devices. Half of the models of telephones do not fulfill the norms because, the control of the norm is outsourced, when it exists. Nor is each mobile device controlled one by one.

At least there should be limits for risk groups. For example, children should never use a cell phone. These risk groups or the health effects of radio frequency could be identified in the telephone user manuals.

The point is that in the well-founded opinion of our speaker in this research, the WHO, as well as the UN, find it difficult to separate themselves from economic interests. Indirectly, these organizations represent the pharmaceutical and telecommunications industry. It is no coincidence that approximately ten years after the adverse health effects of cell phone radiation were known (1994), their results were published (2011). It also depends on who is funding the study, the results are evaluated. The important thing is that the progress in this type of research is real.

Important studies showed that radiofrequency radiation can be linked to certain types of cancer on the same side of the head that users place mobile phones for voice calls, such as cancer of the acoustic nerve and salivary gland. parotid.

There were causal relationships of mobile phone use with cancer in nearby places where mobile phones are kept, such as breast cancer in women who used cell phones lit in their bras or testicular cancer in men who kept the phone in their front pocket pants or in a holster on your hips.

Cancer risk is associated with DNA damage. If cells with damaged DNA reproduce, it is this consequence that causes cancer. The effects on stress proteins are as interesting as they are discouraging, which, when exposed to radiation, over a long period of time, can lead to a reduction in the response of cells and eventual protective reactions of the body. On the other hand, the immune system protects us against infections and diseases. Radiofrequency radiation can cause inflammatory reactions, allergic reactions and change immune function. Several chronic diseases are related to poor immune function.

In conclusion, global state policies are required to comply with at least the limit standards. We should not import phones that exceed these standards. It would be important to increase the level of information for users of the health consequences to which they are exposed. It is thought that, according to marketing criteria, the highest technology available is always the best option, but, with knowledge of the consequences that arise from this research, it is not always the best for people's health. The lack of information should not limit the possibility of choice.

For their part, private individuals can implement precautionary measures such as using the hands-free option rather than calling on mobile phones; opt for the landline phone in offices or at home; send text messages instead of talking; do not expose children to the use of cell phones; keep the mobile phone away from the body, avoid making calls where there is little signal; etc. This type of information needs to come from institutions and organizations.

For this reason, CePETel, in different information and awareness spaces, has been exposing the Precautionary Principle in defense of the rights of colleagues. CePETel had also already organized in August at the University of Quilmes the Seminar on “Non-ionizing radiation, its possible effects on health and the technical solutions of the case”, with Eng. Néstor Mata, Professor at the UTN of White Bay. He spoke on EMC Electropolution, from the first studies on biological effects such as neurological disorders and cancer in radar station operators, to the different international studies on the subject and the adaptation of national legislation in this regard. Also in November 2012, we participated in the National Applied Informatics Meeting (ENIAC), at the Blas Pascal University of the City of Córdoba).

On the other hand, the Director of the IPEI Institute of Cepetel, Cro. Ing. Guillermo Defays, spoke on "Notes on the effect of electromagnetic waves on the population" at the Public Hearing to discuss "Antennas, electromagnetic pollution and its effects on health" within the framework of the Draft Law of Minimum Budgets of Prevention and control of Electromagnetic Pollution, which was carried out in the Honorable Chamber of Deputies of the Nation. After this, comrade Defays participated as a technical consultant, in the Meeting of advisers of the Commission of Natural Resources, also of the Chamber of Deputies of the Nation.

Following this line, CePETel participated in the Meeting of Self-convened Inter-neighborhood Neighbors of Quilmes and Greater Buenos Aires on Electromagnetic Radiations and in the Clarification and Training Day on Electromagnetic Pollution, held in September at the Auditorium of the Museum of Natural Sciences of Fiske Menuco (currently called Gral. Roca - Río Negro). In it, comrade Eng. Guillermo Defays spoke about the effect of electromagnetic waves on the population.

The Precautionary Principle is related to the fact that “if an action or policy involves a probable risk of causing harm to the population or the environment, in the absence of scientific consensus that the harm does not occur, the burden of proof falls on those who they defend action ”. And the CePETel, based on it, intends to continue actions to defend the health of workers and their environment.
