Pregnant women- how cell phone radiation can harm your baby

Attention pregnant women: put down your cellphone. Cellphone radiation exposure during pregnancy impacts fetal brain development and may cause hyperactivity, Yale School of Medicine researchers say.

Dr. Hugh Taylor, a medical professor and chief of Yale's Department of Obstetrics, Gynecology and Reproductive Sciences, co-authored a recent study to probe the impact of cellphone exposure on pregnancies. 'We had pregnant mice in cages and we just simply put a cellphone on top of the cage. In half the mice, the cellphone was active and in half of the ... cages the cellphone was turned off so it wasn't transmitting a signal at all,' Taylor said.

Taylor said the researchers allowed the mice to give birth and waited until offspring were young adults before behaviors were tested. 'The mice exposed to cellphones were more active,' Taylor said. 'Their memory was slightly decreased ... these mice were basically bouncing off the walls and didn't have a care in the world.' So what's the alternative to using cellphones while pregnant?
