Plain English Summary
Japanese researchers exposed human brain and lung cells to radiofrequency radiation at levels similar to cell tower emissions (2.1 GHz) for up to 48 hours. They found no changes in heat shock proteins (cellular stress markers that increase when cells are damaged) even at exposure levels 10 times higher than public safety limits. This suggests that cell tower-level RF radiation does not trigger detectable cellular stress responses in laboratory conditions.
Study Details
An in vitro study focusing on the effects of low-level radiofrequency (RF) fields from mobile radio base stations employing the International Mobile Telecommunication 2000 (IMT-2000) cellular system was conducted to test the hypothesis that modulated RF fields act to induce phosphorylation and overexpression of heat shock protein hsp27
First, we evaluated the responses of human cells to microwave exposure at a specific absorption rate...
Under the RF field exposure conditions described above, no significant differences in the expression...
Our results confirm that exposure to low-level RF field up to 800 mW/kg does not induce phosphorylation of hsp27 or expression of hsp gene family.
