A study done in 2010 by researchers of the UCLA on 29.000 children gave the result that on the age of 7 children have a 50% chance of behaviour problems when regularly exposed to cell-phone radiation in the uterus and in the early childhood.
Possible behavioural problems were hyperactivity, attention disorders and social problems. A previous study on 13.000 Danish children gave similar results.
According to this study the risk for children getting behavioural problems is higher when the uterus was regularly exposed to cell-phone radiation when pregnant. The mechanisms behind this connection have not yet been clarified. It has been suggested that the radiation from cell-phones/laptops have a direct influence on the regulation of hormone secretion, which has an influence on the metabolism and the development of the brain.
