Changes in the activity of certain enzymes in the cells of Cort's organ in guinea pigs after long term exposure to microwaves
Boczyoski E., Zyss R. · 1972
Early research showed microwave exposure altered crucial enzyme activity in guinea pig inner ear structures responsible for hearing.
Plain English Summary
Researchers exposed guinea pigs to microwave radiation for extended periods and measured changes in enzyme activity in the Corti's organ, the hearing structure inside the inner ear. The study specifically examined dehydrogenase and acetylcholinesterase enzymes, which are crucial for cellular energy production and nerve signal transmission. This early research helped establish that microwave exposure could alter biochemical processes in sensitive auditory tissues.
Why This Matters
This 1972 study represents pioneering research into how microwave radiation affects the delicate biochemistry of hearing. The Corti's organ contains some of the most sensitive cells in your body - the hair cells that convert sound waves into electrical signals your brain can interpret. When researchers found that microwave exposure altered enzyme activity in this critical structure, it raised important questions about potential hearing damage from electromagnetic fields.
What makes this research particularly relevant today is that modern wireless devices operate in similar microwave frequency ranges, and we hold these devices directly against our ears during phone calls. The enzymes studied - dehydrogenase and acetylcholinesterase - are essential for cellular energy production and proper nerve function. Changes in their activity could potentially affect hearing sensitivity or contribute to auditory processing problems over time.

Exposure Details
- Power Density
- 25 mW/cm²
- Exposure Duration
- 25 or 50 days
Exposure Context
This study used 25 mW/cm² for radio frequency:
- 2,500Mx above the Building Biology guideline of 0.1 μW/m²
- 41.7Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
To determine the effects of long-term microwave exposure on enzyme activity in the cells of Cort's organ in guinea pigs.
Guinea pigs were exposed to microwave radiation of 10 cm wavelength. The activity of succinyl dehydr...
Decreasing activity of succinyl dehydrogenase and acetylcholinesterase was observed while the activi...
The results indicate that long-term microwave exposure leads to changes in enzyme activity in the cells of Cort's organ, suggesting a weakening of oxygen metabolism and a decrease in bioelectric activity of the organ. The changes in enzyme activity disappeared 30 days after cessation of exposure.
