Discovery Poses Significant Implications for Public Health.
Environmental Health Trust – 11feb2025.
A ground-breaking study commissioned by Environmental Health Trust (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.
The findings, discovered by EHT Vice President for Scientific Research and Clinical Affairs Dr. Robert Brown and his colleague Barbara Biebrich, a senior ultrasound technologist with decades of experience performing vascular ultrasounds, were published Tuesday in the scientific journal, Frontiers in Cardiovascular Medicine.
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.
“Our findings make it clear that, at least in some people, cell phone radiation can lead to observable changes in blood, with potential risks such as reduced oxygen delivery and an increased risk for developing blood clots,” Dr. Brown said.
Key findings include:
- Post-cell phone exposure ultrasound imaging revealed significant aggregation of red blood cells in the veins of a volunteer.
- Rouleaux formation, while reversible, may reoccur often given our constant use of cell phones, and may potentially increase the risk for conditions such as pulmonary embolism, micro-infarcts, stroke, and heart attacks, particularly in vulnerable individuals.
- The study lays the groundwork for a larger, university-led investigation into the prevalence of this phenomenon.

What Does It Mean?
These findings are part of a larger initiative to explore the impact of wireless technology on human health. EHT and a major university will soon begin a larger scale study to learn more.

EHT’s Important Study on Blood Cell Aggregation from Cell Phone Exposure in Environment Magazine—with New Details!
EHTrust.org 25apr2025
Environment: Science and Policy for Sustainable Development released its spring issue today, and it features an article by Dr. Robert Brown, EHT’s Vice President of Scientific Research and Clinical Affairs, about his recently published study on cell phone radiation causing human blood cells to stick together.
Even if you have already read about Dr. Brown’s study in our blog post on the subject, the article in Environment is an important read because it includes new information, discovered after the publication of the initial study — namely that the rouleau effect documented in the study, in which blood cells adhere to each other after five minutes of cell phone exposure, also occurs when a cell phone is held an inch away from the body. The article includes ultrasound images and video of the phenomenon occurring both when a cell phone is touching a volunteer’s body and when the device is simply close to the leg. Click the image to read the article for an explanation of the full impact of this initial research, its implications for human health, and what follow-up research EHT is planning next. As always, distance (or airplane mode) is your friend.
Environment, which is in its seventh decade of publication, invited Dr. Brown to share his groundbreaking study firsthand in the journal’s latest issue, which was released on Earth Day 2025. All readers can access the article for six months free of charge, before it goes behind the subscription paywall.
