Plants exposed to 105 GHz radiation for 2 hours showed stress responses similar to physical damage, suggesting millimeter waves affect living cells.

Plain English Summary

Summary written for general audiences

French researchers exposed flax plant seedlings to 105 GHz electromagnetic radiation (similar to frequencies used in some wireless technologies) for just 2 hours. They found this brief exposure triggered abnormal cell division patterns in the plants, creating clusters of rapidly dividing cells called meristems. The biological response was similar to what the plants showed when exposed to physical stress or mobile phone radiation, suggesting that even non-heating levels of millimeter wave radiation can trigger measurable biological changes in living organisms.

Why This Matters

This study provides compelling evidence that millimeter wave frequencies can trigger biological responses in living systems at non-thermal power levels. The 105 GHz frequency tested falls within the range now being deployed for 5G networks, making these findings particularly relevant as we expand our use of these higher frequency bands. What makes this research especially noteworthy is that the plant response to electromagnetic radiation was comparable to known environmental stressors like cold shock and mechanical damage. The researchers demonstrated that just 2 hours of exposure was sufficient to initiate a cascade of cellular changes that persisted for weeks. While plants aren't humans, they share fundamental cellular processes with all living organisms, and this study adds to the growing body of evidence showing that our bodies can detect and respond to electromagnetic fields at levels well below current safety standards.

Study Details

Exposing seedlings of the flax, Linum usitatissimum L., to a variety of weak environmental stresses followed by a 2 day calcium deprivation, triggers the common response of production of epidermal meristems (actively dividing groups of cells) in the hypocotyl, which is the part of the stem between the root and the cotyledons (the pre-existing leaves in the embryo). This production reaches a plateau of 10-20 meristems after a month in the case of mechanical stimulation and cold shock. Recently, we have shown that radiation from a global system for mobile communication (GSM) telephone also triggers production of meristems with a plateau of around six meristems.

Here, we show that a single 2 h exposure to radiation emitted at 105 GHz at non-thermal levels by a...

Quick Questions About This Study

Yes, research shows millimeter wave radiation can trigger biological changes in plant cells. A 2004 French study found that 105 GHz radiation exposure for just 2 hours caused abnormal cell division patterns in flax seedlings, creating clusters of rapidly dividing cells similar to stress responses.
Studies suggest 5G-range frequencies can trigger cellular responses. Research on 105 GHz radiation (similar to some 5G frequencies) showed it caused abnormal cell division in plants within 2 hours, indicating that millimeter waves can produce measurable biological effects at non-heating power levels.
Research indicates 105 GHz radiation can trigger biological responses in living organisms. A study on flax plants showed this frequency caused abnormal cell division patterns similar to stress responses, suggesting millimeter wave radiation produces measurable effects even at non-thermal power levels.
Millimeter wave exposure can disrupt normal cell division patterns. Research found that 105 GHz radiation triggered the formation of abnormal cell clusters called meristems in plant seedlings, with biological responses similar to those caused by physical stress or mobile phone radiation.
The main documented effect is altered cell division patterns. A 2004 study showed 105 GHz radiation exposure for 2 hours triggered abnormal cellular activity in plants, creating clusters of rapidly dividing cells with kinetics similar to stress responses from environmental stimuli.
