Intense 918 MHz microwave exposure failed to breach the blood-brain barrier despite causing dangerous hyperthermia in rats.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to intense 918 MHz microwave radiation for 30 minutes to see if it would help antibodies cross the blood-brain barrier to fight infections. The microwaves raised body temperature to dangerous levels but failed to allow antibodies into the cerebrospinal fluid. The study found no evidence that microwave exposure could breach the brain's protective barriers.

Quick Questions About This Study

No, this study found that 30 minutes of intense 918 MHz exposure failed to allow streptococcal antibodies to cross into the cerebrospinal fluid, despite causing severe hyperthermia that raised body temperature to 42.5°C in rats.
The microwave radiation raised the rats' core body temperature to 42.5°C (108.5°F), which is dangerously high and well into fever range that could cause serious physiological damage and organ dysfunction.
The researchers used extremely high dose rates of 20-70 mW/g for 30 minutes in a multi-mode cavity, which is far more intense than typical environmental or consumer device exposures.
No, despite creating severe hyperthermia, the 918 MHz microwave exposure produced no evidence of antibody transfer across the cerebrospinal fluid barrier, suggesting these biological barriers are highly resilient.
Serum antibody levels in irradiated rats were only half those of control rats, though high variability made the differences statistically unreliable, suggesting the intense exposure may have impaired immune function.
