According to Columbia University physiology professor Martin Blank, who edited the special issue, the laboratory studies “point to significant interactions” of both power frequency and radio frequency with cellular components, especially DNA.
The epidemiological studies “point to increased risk” of developing certain cancers associated with long-term exposure to radio frequency, he said.
Dr. Lennart Hardell is among the scientists who contributed to the special edition of the journal. T he oncologist from Sweden’s University Hospital found that after one or more years of cellphone use, there is a 5.2-fold elevated risk of malignant brain tumour in children who begin using mobile phones before the age of 20 years; the odds for other ages was 1.4. “There should be special precaution for children and young persons about the use of mobile phones,” Hardell said in an interview.
