Plain English Summary
Polish researchers exposed human blood platelets to 900 MHz cell phone radiation for 1-7 minutes and measured two key indicators of cellular damage: antioxidant enzyme activity and oxidative stress markers. The radiation significantly reduced the cells' natural antioxidant defenses while increasing markers of cellular damage at most exposure times. This suggests that even brief exposure to cell phone radiation can trigger oxidative stress, which the researchers say could lead to widespread cellular damage and health problems throughout the body.
Why This Matters
This study adds to the growing body of evidence showing that radiofrequency radiation triggers oxidative stress at the cellular level. What makes this research particularly significant is that it demonstrates measurable biochemical changes in human blood cells after just one minute of exposure to 900 MHz radiation - the same frequency used by many cell phones. The depletion of superoxide dismutase (SOD-1), a critical antioxidant enzyme, combined with increased malondialdehyde (MDA), a marker of cellular damage, points to a fundamental disruption of cellular protective mechanisms. The reality is that oxidative stress is implicated in numerous chronic diseases, from cardiovascular problems to neurological disorders. While this was an in vitro study using isolated platelets, it provides important mechanistic evidence for how EMF exposure might contribute to health problems. The brief exposure times that produced these effects are concerning given that most people carry phones that emit similar radiation throughout the day.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 900 MHz Duration: , 3, 5, and 7 min
Study Details
The aim of the study was to assess in vitro the effect of electromagnetic field produced by mobile phones on the activity of superoxide dismutase (SOD-1) and the level of malonyldialdehyde (MDA) in human blood platelets.
The suspension of blood platelets was exposed to the electromagnetic field with the frequency of 900...
Our studies demonstrated that microwaves produced by mobile phones significantly depleted SOD-1 acti...
On the grounds of our results we conclude that oxidative stress after exposure to microwaves may be the reason for many adverse changes in cells and may cause a number of systemic disturbances in the human body.
