There is no conclusive scientific evidence for the negative effects of electromagnetic fields.
The truth is, as always, lies in the middle. The radiofrequencies that will be used for the next-generation 5G network are not entirely new and unexplored. The radiofrequency spectrum has been used over the past decades in mobile communications, base stations, and other wireless technologies. This spectrum has been researched for the last 50 years by different groups of scientists on the matter of potential health effects of the generated electromagnetic field (EMF). According to the conclusion of the World Health Organization (WHO), at the moment there is no experimental evidence of the harm of electromagnetic radiation from mobile devices at radiation levels below the maximum permissible limits recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
However, the potential of the negative effects should not be ruled out. In 2011, the International Agency for Research on Cancer (IARC) classified radio frequency electromagnetic fields, including those generated by mobile communications, as “possibly carcinogenic” - potentially causing cancer. Scientists have investigated the relationship between electromagnetic fields generated by mobile equipment and the risk of developing brain cancer, and no direct causal relationship was found. It should be noted that coffee and pickled vegetables as well are classified as “possibly carcinogenic”.
There are several experiments confirming the possibility of the negative influence of electromagnetic fields on living organisms. In the USA, within the framework of the National Toxicology Program (NTP), a study of the effect of 2G and 3G in rats was carried out for 10 years. The experiment showed that males exposed to electromagnetic radiation from 2G and 3G throughout their lives have an increased incidence of cancers of the heart, brain, and adrenal glands. These results were later confirmed by a study of the Ramazzini Institute. However, the scientific community notes that these results cannot be directly compared to the impact people receive from using mobile phones. During the experiment, rats were exposed to radiation all over the body, while people are directly exposed only in the areas close to the phone. Moreover, the level of the electromagnetic field and the duration of exposure used during the experiment were much higher than it is during the actual use of mobile technologies by people.
