Epidemiological evidence on health risks of cellular telephones.
The Lancet, vol.356, November 25,2000, pg. 1837-40
It is too soon for a verdict on the health risks from cellular telephones in view of changing technology. From the Interphone project and some other large studies in progress, better information may emerge. Based on the epidemiological evidence available now, the main public-health concern is clearly motor vehicle collisions, a behavioural effect rather than an effect of radiofrequency exposure as such. Neither the several studies of occupational exposure to radiofrequencies nor the few cellular telephones users offer any clear evidence of an association with brain tumours or other malignancies. Even if the studies in progress were to find large relative effects for brain cancer, the absolute increase in risk would be probably much smaller than the risk of motor vehicle collisions. Cellular telephone affects the quality of life in many ways – for good and ill, the health risk is just one part of a picture.
