Abstract

Overview

The study investigates the bioeffects of long-term and multigenerational exposure to microwaves using Caenorhabditis elegans as a model organism. Unlike many studies that employ rodents or cells which can offer variable control conditions and shorter irradiation periods, this research provides extended exposure analysis.

Findings

  • Exposure Details: Worms were exposed to 9.4 GHz microwaves at a rate of 4 W/kg for 10 hours daily, from early larval stages to adulthood over 20 generations.
  • Generational Observations: Significant findings were observed from the 10th generation onwards, including decreased fecundity by the 15th generation, reduced growth and motility, and increased signs of oxidative stress.

Conclusion

Exposure to microwave energy appears to induce oxidative stress in C. elegans, contributing to observed health declines across multiple generations. This suggests potential long-term health risks associated with electromagnetic fields. Further investigations into the underlying mechanisms are recommended to better understand these effects and assess the broader implications regarding human exposure to such fields.
