The Healthier Tech Podcast

In this episode, Andrew McAfee, electrical engineer, EMF consultant, and inventor of the nuisance current blocker, answers live questions after a replay of his conversation with Dr. Sam Milham, one of the first scientists to document health effects in people working around electricity.
McAfee explains why voltage alone tells you almost nothing about your real exposure, and what to actually measure and fix instead. And he has lived this at the extreme, uprooting his life to Green Bank, West Virginia, one of the only radio quiet zones left in the country.
Here's what you'll learn:
Why a meter reading zero volts can still mean current is flowing through your body, and why that current is constantly ionizing and deionizing your cells
Why dirty electricity filters can backfire and make your magnetic field exposure worse if your home wiring already has a code violation
How Andrew uses a simple copper rod and a gauss meter to find and redirect "rivers" of ground current crossing a property
What to test for before buying a car, including exact gauss thresholds for your feet, seat, and head, and why to pull the Bluetooth chip before you drive it home
Why DC electricity is fundamentally safer for the body than AC, and why almost no one can practically build a fully DC home today
Andrew McAfee came to this work through his own health crisis caused by faulty wiring in his home, then spent years mastering both the trade of electrical work and the science of EMF health effects, a combination R Blank says he has rarely seen in one person.
McAfee worked directly alongside Dr. Sam Milham, whose research and book, Dirty Electricity, shaped much of what we understand today about electromagnetic fields and health, and he credits Dave Stetzer, the researcher behind the dairy cattle studies that first established ground current exposure thresholds. McAfee now lives in the Green Bank National Radio Quiet Zone, a federally protected area with no cell towers and no 5G, where he is working with Children's Health Defense lawyers to strengthen state radiation limits to protect residents, not just the Green Bank Observatory's telescope.
If you have ever measured zero volts in your home and assumed that meant you were safe, this conversation will change how you think about what your wiring is actually doing to your body.

Turkish researchers exposed pregnant rats to WiFi-frequency radiation throughout pregnancy, then examined their offspring's thyroid glands one full year after birth. What they found reveals something troubling about prenatal EMF exposure.
In this episode, I walk through a new study that tracked thyroid damage from prenatal WiFi exposure for an entire year after birth. The findings show that EMF exposure during pregnancy doesn't just affect development in the womb -- it creates lasting biological changes that persist well into adulthood.

A new study found that twelve weeks of exposure to cell phone frequency radiation caused significant hormonal disruption, reduced sperm quality, and increased anxiety in laboratory rats -- and the effects persisted even after exposure stopped.
In this episode, I break down a twenty twenty-five study that exposed rats to eighteen hundred megahertz electromagnetic fields -- the same frequency used by GSM mobile networks worldwide. The findings reveal how EMF exposure affects multiple biological systems simultaneously, from stress hormones to reproductive health.

What happens when a cell tower goes up outside your bedroom window, makes you sick, and the law says you have no right to do anything about it?
In this episode of The Healthier Tech Podcast, R Blank sits down with health and environmental advocate Camilla Rees and attorney Scott McCollough to unpack one sentence buried in the 1996 Telecom Act that took away your town's power to stop a cell tower on health grounds. Thirty years later, courts have stretched that same sentence into a liability shield, so when the infrastructure outside your home makes you sick, the traditional remedies you would have against any other polluter simply do not exist. And right now, for the first time in decades, two federal agencies are finally asking the public what wireless exposure is doing to their health.
Here's what you'll learn:
How Section 704 of the Telecom Act strips your local zoning board of the power to reject a tower on health or environmental grounds, and why that one clause explains the last thirty years of wireless buildout
Why courts ruled that trespass, nuisance, and personal injury claims are all preempted by federal law, leaving people who get sick from a nearby tower with no remedy at any level of government
How the FCC's exposure limits measure only heating, while the FDA approves medical devices every day that use radio frequency radiation specifically because it changes biology
What the W90 radiation sickness diagnostic code reveals about the gap between what federal health agencies will reimburse and what federal communications regulators will admit exists
Why the US sits at 23 percent fiber to the home while South Korea sits at 96 percent, and how that gap keeps the country locked into wireless by design
Scott McCollough has spent more than forty years litigating telecommunications and utility law, and serves as Chief Litigation Counsel for Children's Health Defense's Electromagnetic Radiation and Wireless program. In 2021 he and Environmental Health Trust won a DC Circuit ruling that the FCC's decision to leave its radiation guidelines untouched was irrational. The FCC then sat on that order for five years. In this conversation he lays out the next case, filing within a month, built around people who tried to stop a tower, failed, got sick, and were told nothing could be done. Camilla Rees has worked on the biological effects of EMFs for nearly twenty years, co-authored "The Safety of Wireless Technologies: The Scientific View" with Richard Lear, founded Manhattan Neighbors for Safer Telecommunications and ElectromagneticHealth.org, and now serves as Senior Policy Advisor at NISLAPP. She also speaks from personal experience, having moved twice at significant expense to get away from exposures that affected her health.
If you have ever watched a tower go up near your home and wondered why nobody at city hall could stop it, this conversation will change how you think about who actually controls the air around your property.

A large-scale study tracking over sixteen hundred pregnant women in Iran has found a measurable link between cell phone use and pregnancy outcomes -- including miscarriage, abnormal birth weight, and infant height.
In this episode, I break down the findings from researchers who measured real-world electromagnetic exposure during pregnancy over a four-year period. The results show a dose-response relationship: the more cell phone exposure, the greater the risk. What makes this particularly concerning is that these effects occurred at exposure levels millions of pregnant women experience every day.

A new study reveals concerning effects when testicular tissue is exposed to the exact frequencies used in modern wireless networks. Researchers found measurable changes in immune function, gene expression, and sperm quality.
In this episode, I break down a twenty twenty-five study that exposed rats to three point five gigahertz and twenty-four gigahertz radiofrequency radiation -- the frequencies used in WiFi and five G networks. The findings suggest these exposures may affect male reproductive health in ways we're only beginning to understand. I explain what the research found, why it matters for your everyday life, and one simple step you can take today.

New research reveals that the timing of EMF exposure during pregnancy may be just as important as the intensity -- and late pregnancy appears to be a critical vulnerability window.
In this episode, I break down a study that exposed pregnant rats to cell phone frequency radiation at different stages of pregnancy. The findings reveal a specific developmental window when exposure triggers significant brain cell death in offspring -- and it corresponds to a period when many pregnant women are still using their phones without concern.

Chinese military researchers found that electromagnetic pulses can break down the blood-brain barrier -- your brain's primary defense against toxins -- in just two weeks.
In this episode, I break down a new study from China's Airforce Medical University that reveals the exact biological pathway through which pulsed electromagnetic fields trigger brain inflammation and compromise the protective barrier that keeps harmful substances out of your brain. The findings matter because they show concrete mechanisms of EMF damage to the central nervous system -- and the exposure timeframe was surprisingly short.

Thyroid problems are on the rise -- especially among women -- and a new study reveals an unexpected factor that may contribute to lifelong thyroid dysfunction.
Turkish researchers exposed pregnant rats to WiFi-frequency radiation throughout pregnancy, then examined their offspring's thyroid glands one year after birth. The results show significant and persistent damage -- including increased cell death, DNA breaks, and tissue scarring -- that didn't heal over time. This suggests prenatal WiFi exposure may cause thyroid problems that last well into adulthood.
