| Today, the social debate continues, regarding the potential negative effects on our health that can produce the Non-ionizing radiation (NIR).

| At CEM-Ti we continue giving support "affected people", since we find people daily who tell us "their testimonies", and the disorders they suffer when they have prolonged exposure to high levels of radiation (headaches, muscle pain, depression, unjustified tiredness, etc.).

| The World Health Organization (WHO) itself classified in May 2011, through the IARC, Agency of the WHO: "International Agency for Research on Cancer", electromagnetic radiation EMF-RF, within Group 2B ( "possible human carcinogen"). Although, a significant minority of the working group itself called for the most serious classification: Group 2A ("probable human carcinogen").

| With all this, the WHO continues without including Electrohypersensitivity (EHS), in its catalog of "recognized diseases".

▌What originates it?

The emitters of high-frequency electromagnetic fields (HF), which we can normally find are mobile phone antennas and municipal WI-FI wireless network antennas, radars, television and radio antennas, small home wireless appliances such as : Wi-Fi routers, DECT cordless phones, mobile phones, ...

On the other hand, the most common sources of low frequency (LF) electromagnetic emissions would be electrical transformation centers, medium/high electrical voltage lines (industrial frequency of 50 Hz), and railway lines (frequency 16 Hz), and defective home electrical installations, appliances such as: microwave, dryer...

▌Does it affect animals?

There are also studies that show that the effects of EMF also affect animals, for example, in the reproduction of birds such as storks or sparrows with nests near telephone masts, in Valladolid ("Possible Effects of Electromagnetic Fields from Phone Masts on a Population of White Stork (Ciconia ciconia)"), 2005, by Biologist Alfonso Balmorí, member of the Superior Body of Biologists of the Junta de Castilla y León (Spain).

One of the conclusions obtained from the study carried out is that in the nests studied within from a circle of 200 m to these antennas, productivity (successfully raised chicks) is half that of the nests studied at more than 300 m Another conclusion, which can be drawn, is that 40% of the nests do not they manage to remove any young, while this only occurs in 3.3% of the furthest group of nests.

▌Precautionary principle.

At CEM-Ti , we recommend taking protective measures to comply with the Precautionary principle, especially for those people who are living near sources of contamination close to their habitual residence, who consequently have high exposure times.

• If you can choose, DO NOT LIVE in environments close to major sources of EMF contamination (telephone masts, high-voltage electrical distribution lines, electrical transformers,...etc). If you don't have a choice, and you live in these environments, you should screen your home to reduce EMC levels in your home.
• MODERATE THE USE of the mobile phone, and use it only for calls of real necessity, which you cannot avoid in any other way. When you have to talk through a mobile terminal, try to keep it away from your head as much as possible (do not speak holding the terminal to your head). Never charge the terminal on your nightstand, close to your head, while sleeping.
• AVOID USING DECT cordless telephony whenever possible. If you can, use fixed telephony (by cable).
• AVOID THE USE of WiFi technologies. It is preferable to use wired data networks. If the distance is small, please connect to the router via a data cable (UTP), and disable the Wi-Fi connection of the router
• MODERATE THE USE of electrical appliances, and use their "mechanical" substitute ("instead of the vacuum cleaner, the broom", "instead of the microwave oven, heat with the conventional oven", ...etc). If you have to use them compulsorily, do not forget to disconnect them from the electrical network when you finish.

▌History and Studies.

Work at the Karolinska Institute in Stockholm (Sweden), in 1992, revealed that there is a risk of contracting leukemia when the magnetic field to which children are chronically subjected exceeds 0.2 μT (microtesla).

Risk that increases as the magnitude of the magnetic field increases. In this way, one can speak of a moderate association or risk in the case of 0.2 μT and a high risk when it exceeds 0.3 μT.

The "Paris Declaration", of March 23, 2009, represents the "enough is enough", by the European scientific community, which day by day confirms the evidence that there are adverse health effects in this type of emissions.

In May 2011, the "International Center for Research on Cancer (IARC)", a specialized agency within the World Health Organization, announced that mobile phones had been classified by the WHO as "possibly carcinogenic" for the man."

Electrification in industrialized countries has progressively increased the average level of exposure to low-frequency electromagnetic fields (EMF) to which the population is exposed; those EMFs are substantially above the natural EMFs of about 10(-4) Vm and about 10(-13)T, respectively. Several epidemiological studies have concluded that EMF exposure is associated with an increased risk of contracting cancer, particularly leukemia in children.

| Teratogenic effects (on the fetus)

Juutilainen et al. 1993 concluded that women exposed to magnetic fields of domestic origin during their pregnancy with intensities greater than 0.63 μT had a higher risk of abortion than those women exposed to a magnetic field less than 0.13 μT".
