Plain English Summary
Researchers exposed zebrafish to cell phone radiation (GSM 900 MHz) for 14 days at human-equivalent levels. The fish developed increased anxiety, reduced social behavior, and impaired learning, plus brain oxidative stress indicating cellular damage. This suggests everyday cell phone radiation may affect brain function.
Why This Matters
This research is particularly significant because it demonstrates measurable neurological effects at SAR levels (1.34 W/kg) that fall within typical cell phone exposure ranges for humans. The study's use of zebrafish is valuable because these organisms share fundamental neurological pathways with humans, making the behavioral changes observed highly relevant to human health concerns. The combination of behavioral impairments and oxidative stress markers suggests that cell phone radiation can simultaneously affect both brain function and cellular health. What makes this study especially compelling is that the researchers also tested melatonin as a protective agent and found it could reverse many of the radiation-induced changes. This points to potential biological mechanisms and protective strategies, while reinforcing that the observed effects were indeed caused by the EMF exposure rather than other factors.
Exposure Details
- SAR
- 1.34 W/kg

Where This Falls on the Concern Scale
Study Details
Herein, we evaluated the impact of GSM900MP (GSM900MP) radiation exposure daily for 1 hr for 14 days with the SAR of 1.34W/Kg on neurobehavioral and oxidative stress parameters in zebrafish.
Our study revealed that, GSM900MP radiation exposure, significantly decreased time spent near social...
This study traced GSM900MP radiation exposure induced neurobehavioral aberrations and alterations in brain oxidative status. Furthermore, MT proved to be a promising therapeutic candidate in ameliorating such outcomes in zebrafish.
