Cell phone radiation up to 3.6 W/kg didn't trigger stress proteins in immune cells, but this tests only one biological pathway.

Plain English Summary

Summary written for general audiences

Researchers exposed human white blood cells to 900 MHz cell phone radiation at various power levels for up to 4 hours to see if it triggered a cellular stress response. The cells showed no signs of producing stress proteins (the body's natural defense against harmful conditions) after RF exposure, even though they did respond normally when heated to 42°C. This suggests that cell phone-type radiation at these levels doesn't cause detectable cellular stress in immune cells.

Study Details

The aim of this study was to determine whether exposure to mobile phone-type radiation causes a nonthermal stress response in human leukocytes.

Human peripheral blood was sham-exposed or exposed to 900 MHz fields (continuous-wave or GSM-modulat...

Heat caused an increase in the number of cells expressing stress proteins (HSP70, HSP27), measured u...

These results suggest that mobile phone-type radiation is not a stressor of normal human lymphocytes and monocytes, in contrast to mild heating.
