WiFi-frequency radiation disrupted blood cell production and caused genetic damage in rats, raising questions about long-term wireless device safety.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to WiFi-frequency radiation (2.45 GHz) for 2 hours daily over weeks. The exposure initially damaged blood cells and disrupted bone marrow production, but effects normalized by study's end, suggesting rats may adapt to chronic microwave exposure.

Why This Matters

This study reveals something concerning about microwave radiation exposure at levels comparable to what we encounter from WiFi routers and other wireless devices. The SAR level of 1.25 W/kg is actually within the range of everyday wireless device exposures, making these findings directly relevant to human health questions. What's particularly noteworthy is that the researchers observed both disrupted blood cell production and genetic damage markers in the early stages of exposure. While the study authors interpret the later normalization as 'adaptation,' this could equally represent the exhaustion of cellular repair mechanisms or the body's inability to maintain protective responses under chronic stress. The reality is that we don't fully understand whether such 'adaptation' represents genuine protection or simply masked ongoing damage. This research adds to the growing body of evidence suggesting that chronic microwave exposure affects fundamental biological processes, even at supposedly safe levels.

Study Details

The aim of study was to define influence of radiofrequency microwave (RF/MW) radiation on erythropoiesis in rats.

Such findings are considered to be indicators of radiation effects on BM erythropoiesis consequently reflected in the PB. Rehabilitated dynamic haemopoietc equilibrium in rats by the end of experiment indicates possibility of activation adaptation process in rats to the selected experimental conditions of subchronic RF/MW exposure.
