Abstract

Overview

High-power microwaves, known for inhibiting electronics of vehicles, pose potential health risks. This study investigates the hazard levels associated with modulated radiofrequency exposures akin to those from early mobile phones.

Experimental Setup

• Rats underwent exposure to intense electric fields of one megavolt per meter, with differences in exposure frequency and duration.
• Exposure scenarios included both single acute and repeated sessions over eight weeks, with specific focus on the effects on the central nervous system and overall survival.

Findings

• Initial tests like behavioural assessments showed minimal effects, but significant findings included:
• An avoidance reflex post-acute exposure suggesting high thermal stress.
• Increased levels of the brain inflammation marker GFAP following exposure.
• Most critically, rats with repeated exposures had a median survival time shortened by four months and an increased incidence of large sub-cutaneous tumors.

Conclusion

Repeated exposure to high-power microwaves, even below thermal level, notably increases cancer prevalence and reduces survival time in rats, highlighting a clear health risk. Further investigation into the specific parameters of this effect and more accurate dosimetry is needed.
