View Original AbstractJust 45 minutes of cell phone-level radiation exposure significantly altered brain chemistry in this study, raising questions about wireless devices' neurological effects.
Plain English Summary
Researchers exposed rats to cell phone-level radiofrequency radiation (900 MHz) for just 45 minutes and measured changes in brain chemicals. They found that this brief exposure significantly increased blood serotonin levels, a neurotransmitter that affects mood and cognitive function. The researchers note this serotonin increase could potentially impact learning and memory abilities.
Why This Matters
This study adds to the growing body of evidence showing that radiofrequency radiation can affect brain chemistry at exposure levels comparable to cell phone use. The 608 mW/m² exposure used here falls within the range of what you might experience during a phone call held close to your head. What makes this research particularly noteworthy is that measurable neurochemical changes occurred after just 45 minutes of exposure. Serotonin plays crucial roles in mood regulation, sleep, and cognitive function, so alterations in its levels could have meaningful implications for brain health. While this was an animal study with a small sample size, it aligns with other research demonstrating that EMF exposure can influence neurotransmitter systems. The reality is that we're conducting a massive experiment on ourselves and our children with wireless technology, and studies like this suggest our brains are responding to these exposures in ways we're only beginning to understand.

Study Details
The aim of this study is to investigate Effect of Short-term 900 MHz low level electromagnetic radiation exposure on blood serotonin and glutamate levels
Ten male Wistar Albino rats were anesthetized 30 min before the LLER exposure, 0.5 ml blood was take...
Plasma 5-HT and glutamate levels were measured by enzyme immunoassay (EIA) using commercial kits. It...
It was concluded that even a single 45 min of LLER exposure may produce an increase in 5-HT level without changing the blood glutamate level. Increased 5-HT level may lead to a retarded learning and a deficit in spatial memory (Tab. 2, Fig. 2, Ref. 24).
