RISKS OF CARCINOGENESIS FROM ELECTROMAGNETIC RADIATION OF MOBILE TELEPHONY DEVICES
Abstract:
Intensive implementation of mobile telephony technology in everyday human life during last two decades has given a possibility for epidemiological
estimation of long-term effects of chronic exposure of human organism to low-intensive microwave (MW) radiation. Latest
epidemiological data reveal a significant increase in risk of development of some types of tumors in chronic (over 10 years) users of mobile
phone. It was detected a significant increase in incidence of brain tumors (glioma, acoustic neuroma, meningioma), parotid gland tumor,
seminoma in long-term users of mobile phone, especially in cases of ipsilateral use (case-control odds ratios from 1.3 up to 6.1). Two
epidemiological studies have indicated a significant increase of cancer incidence in people living close to the mobile telephony base station
as compared with the population from distant area. These data raise a question of adequacy of modern safety limits of electromagnetic
radiation (EMR) exposure for humans. For today the limits were based solely on the conception of thermal mechanism of biological effects
of RF/MW radiation. Meantime the latest experimental data indicate the significant metabolic changes in living cell under the low-intensive
(non-thermal) EMR exposure. Among reproducible biological effects of low-intensive MWs are reactive oxygen species overproduction,
heat shock proteins expression, DNA damages, apoptosis. The lack of generally accepted mechanism of biological effects of low-intensive
non-ionizing radiation doesn’t permit to disregard the obvious epidemiological and experimental data of its biological activity. Practical
steps must be done for reasonable limitation of excessive EMR exposure, along with the implementation of new safety limits of mobile
telephony devices radiation, and new technological decisions, which would take out the source of radiation from human brain.
Key Words: tumor, radiofrequency radiation, microwaves, mobile phone, risk assessment, non-thermal effects.
