Cell phone radiation at legal SAR limits damaged liver and pancreatic cells in rats within just one week of exposure.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to cell phone radiation (GSM 900 MHz) for either 3 or 6 hours daily over 7 days to study effects on insulin production and organ health. While insulin levels remained unchanged, the radiation caused inflammatory damage in the liver and harmed insulin-producing cells in the pancreas, with longer exposure times producing more severe damage.

Why This Matters

This study reveals a concerning pattern: even short-term exposure to cell phone radiation can damage critical metabolic organs. The 2.0 W/kg exposure level used here is at the current SAR safety limit for mobile devices, meaning the liver and pancreatic damage occurred at radiation levels your phone is legally allowed to emit. What makes this particularly significant is that the researchers found dose-dependent effects - longer daily exposure (6 hours versus 3 hours) produced more severe organ damage. The science demonstrates that our current safety standards may not adequately protect these vital organs that regulate blood sugar and detoxification. While this was a short 7-day study, it raises important questions about what chronic, years-long exposure might do to liver and pancreatic function in humans.
