View Original AbstractCell phone frequency radiation caused significant brain cell loss in young rats, suggesting children's developing brains face particular risk from device exposure.
Plain English Summary
Researchers exposed young rats (equivalent to pre-adolescent humans) to 900-MHz cell phone radiation for one hour daily over 30 days, then examined their brain tissue. They found significant loss of pyramidal neurons in the hippocampus (a brain region crucial for memory and learning) and observed damaged cells with abnormal appearance. This suggests that cell phone radiation exposure during development may harm critical brain cells needed for cognitive function.
Why This Matters
This study adds to mounting evidence that developing brains are particularly vulnerable to radiofrequency radiation. The researchers specifically chose 8-week-old rats because this age corresponds to the pre-adolescent period in humans - exactly when many children begin using smartphones intensively. The hippocampus damage observed here is especially concerning because this brain region is essential for memory formation and learning. While the study doesn't specify exact power levels, 900-MHz is the same frequency used by many cell phone networks worldwide. The reality is that children today receive far more cumulative exposure than the one hour daily used in this experiment, often carrying phones in pockets or sleeping next to them. What this means for you: the developing brain appears more susceptible to EMF damage than adult brains, supporting the case for stronger precautions around children's device use.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 900-MHz Duration: 1 h/day for 30 days
Study Details
Children are at potential risk due to their intense use of mobile phones. We examined 8-week-old rats because this age of the rats is comparable with the preadolescent period in humans. The number of pyramidal neurons in the cornu ammonis of the Sprague Dawley male rat (8-weeks old, weighing 180–250 g) hippocampus following exposure to a 900 MHz (MHz) electromagnetic field (EMF) were examined.
The study consisted of control (CN-G), sham exposed (SHM-EG) and EMF exposed (EMF-EG) groups with 6 ...
Histopathological observation showed abundant cells with abnormal, black or dark blue cytoplasm and ...
In conclusion, our results suggest that pyramidal neuron loss and histopathological changes in the cornu ammonis of 8-week-old male rats may be due to the 900-MHz EMF exposure
