There is no scientific basis
for investigating exposure of the growing baby when pregnant mothers use a mobile phone, as exposure to
radiofrequency radiation from mobile phones is highly localised to the part of the head closest to the phone; there is no evidence to suggest that other parts of the body, such as the abdomen where the baby is growing, are affected by mobile phone use.
The new research was conducted on rats by the U.S. National Toxicology Program, which exposed rats to
radiofrequency radiation that comes from cell phones
for about nine hours a day
for seven days a week.
