Cape Town – An American scientist has warned that children and pregnant women should avoid using cellphones, cordless phones, tablets and smartphones that use wi-fi as such devices expose them to wireless radiation that could cause cancer. Dr Devra Davis, an environmental health researcher and head of the US-based Environmental Health Trust said not only do pregnant women expose their unborn babies to a possible human carcinogen, there was evidence that cellphone radiation negatively affected the development of a foetus. Speaking at the Cancer Association of South Africa (CANSA) about harmful environmental factors during pregnancy, Davis said various prenatal animal studies had proven that cellphone radiation altered the DNA and brain metabolism, exposed newborns to compromised spinal cords and affected learning abilities. In males it reduced sperm count.
