A single 45-minute exposure to 900 MHz low-level electromagnetic radiation increased blood serotonin levels in rats, while glutamate levels remained unchanged.

Plain English Summary

Summary written for general audiences

Researchers exposed ten male Wistar Albino rats to 900 MHz electromagnetic radiation at 15.14 V/m for 45 minutes and measured blood serotonin and glutamate levels before and after. Blood plasma serotonin and glutamate levels were measured using enzyme immunoassay. A single 45-minute exposure significantly increased blood serotonin levels but did not change glutamate levels.

Why This Matters

Blood samples were taken from the tail vein before exposure to establish control values, and again after exposure to determine treatment values. The field applied to the head region was described as 15.14 V/m (608 mW/m(2)) in strength with 100 kHz FM modulation at 900 MHz. The researchers concluded that even a single 45-minute exposure may produce an increase in serotonin without changing blood glutamate. The researchers noted that an increased serotonin level may lead to retarded learning and a deficit in spatial memory.

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).
