Prolonged exposure to waves emitted by a mobile phone during pregnancy in mice leads to nervous disorders and behavior, according to an article published in Nature, which emphasizes that it is difficult to translate these results to humans.
We have shown that fetal exposure to radio frequency 800-1900 Mhz cell phone leads to neurophysiological and behavioral alterations that persist into adulthood, suggest researchers in an article in biology from Yale University in the U.S. States.
Mice exposed during gestation have an impaired memory, are hyperactive with less anxiety, indicating that intra-utero exposure to RF is a potential cause of neurobehavioral disorder, they say.
For this experiment, the phones were placed just above the mouse cages for the duration of their short gestation (19 days) for a group with active devices such as during a call but muted and a control group of mobile disabled.
No difference was noted for births. When adult mice of both groups were subjected to the same battery of tests that could demonstrate that such mice exposed in utero were hyperactive and had memory problems.
U.S. researchers have noted a parallel correlation between the length of wave exposure and effects on mice, suggesting that safety limits, particularly for pregnant women can be established.
But, it is difficult to translate these résulats risks to humans recognize U.S. researchers.
In mice, newborns are born with a brain proportionately less developed than in humans.
Further experiments are needed in humans and primates to determine if the risk is similar and to set limits in terms of exposure (to the airwaves, ed) for pregnant women, researchers found these biologists.
