Health problems related to the use of cellular telephones become a „hot“ journalistic topic. Incompetent and uniformed authors of newspaper articles inform, deform and sometimes even frighten their users with malignant effects of electromagnetic radiation starting with impairment of psychic concentration, sleep disorders till development brain tumors. Such (and so far not proved apprehensions) have to be confound with scientific arguments. One of the first studies aimed at possibility of brain tumor formation brought about negative answer. The lack of empirical evidences of the mobile phone electromagnetic radiation cancerogenity suggest that cellular phones do not represent a serious risk of cancer.

        Key words: cellular telephones, electromagnetic radiation, brain tumors, temperature of the brain tissue.
