Ultrasound Study Reveals Wireless Radiation Can Cause Blood Cells to Stick Together
A groundbreaking study commissioned by EHT reveals a startling discovery about the effect of cell phone radiation on human blood. Using diagnostic ultrasound, researchers have documented that exposure to an active cell phone can cause red blood cells to clump together, forming aggregates large enough to be visible on imaging. This phenomenon, known as “rouleaux formation,” has significant implications for public health.
Unlike previous studies relying on the controversial technique of live blood cell analysis in vitro, or samples placed on microscope slides, this study was done in vivo using ultrasonography, a widely available and reliable diagnostic tool routinely used for the evaluation of blood vessels.

get the new, expanded, and updated version of disconnect
Acclaimed and award-winning scientist Dr. Devra Davis shares a compelling cautionary tale, supported by a growing body of evidence surrounding alarming new scientific understandings of cell phones, other commonly used microwave radiating devices, and the new 5G network currently being built-out nationwide – all with limited safety testing!
Building upon the shocking revelations that Dr. Davis uncovered through research and interviews and shared in the 2010 first edition, this new, expanded edition released in 2024 adds recent studies that substantiate and confirm the radiation risks of the “connected world” that endanger our health and the world around us. Understanding that personal electronic devices are here to stay, Dr. Davis shows us the simple safety measures we must take. Sharing these researched solutions, she reminds us that now is the time to implement them — before it’s too late.
