Abstract

Overview

Despite considerable research, uncertainties persist about the health impacts related to radiofrequency (RF) field exposures.

Findings

This investigation focused on the ramifications of early-life exposure to pulsed LTE 1,846 MHz radiofrequency signals on innate behaviors in mice. Key study characteristics include:

  • Duration: Exposure spanned from late gestation through weaning.
  • Frequency: 30 minutes daily, five days a week.
  • Intensity: Whole-body average specific energy absorption rate (SAR) was either 0.5 or 1 W/kg.

Behavioral effects, analyzed via a tracking system, were noticeable in locomotion and appetitive behaviors across different SAR levels:

  • At 0.5 W/kg, there was a significant decrease in drinking frequency and movement distance.
  • At 1 W/kg, results showed a significant increase in both drinking frequency and moving duration.

Conclusion

The observed behaviors suggest a significant and long-lasting impact of early-life RF field exposure at low levels, endorsing the potential for persistent changes in adult behavior.
