Plain English Summary
Spanish researchers exposed rats to 2.45 GHz radiation (the same frequency as Wi-Fi and microwave ovens) and found significant changes in thyroid gland structure. The radiation caused thyroid follicles to swell and shrink in different patterns depending on exposure duration and power levels. These structural changes suggest the thyroid gland was responding to radiation stress, raising questions about potential long-term effects on thyroid function in humans exposed to similar frequencies.
Why This Matters
This study adds important evidence to our understanding of how radiofrequency radiation affects endocrine function, specifically the thyroid gland that regulates metabolism, growth, and development. The 2.45 GHz frequency used is identical to what you encounter from Wi-Fi routers, Bluetooth devices, and microwave ovens. What makes this research particularly relevant is that the thyroid sits in your neck, directly in the path of radiation from cell phones held to your ear. The researchers observed measurable structural changes in thyroid tissue after just 30-minute exposures, with different effects from single versus repeated exposures. While we can't directly extrapolate from rat studies to humans, the thyroid's sensitivity to radiation stress documented here aligns with growing concerns about EMF effects on hormone-producing glands. The researchers themselves noted these changes 'may indicate a glandular response to acute or repeated stress from radiation' and called for further research into potential disease development over time.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 2.45 GHz Duration: (10 times in two weeks) for 30 min
Study Details
We used a diathermy model on laboratory rats subjected to maximum exposure in the left front leg, in order to study the effects of radiation on the nearby thyroid tissue.
Fifty-six rats were individually exposed once or repeatedly (10 times in two weeks) for 30 min to 2....
Ninety minutes after radiation with the highest SAR, the central and peripheral follicles presented ...
