FAQs

Many people refer to mobile phone radiation as electromagnetic field (EMF) radiation. However, EMF encompasses a very large spectrum of frequencies, which often leads to confusion. Cell phones emit multiple EMF frequencies both to function as electrical devices and to transmit signals to cellular towers. Virtually all studies related to the negative health effects of cell phone use refer to the high-frequency RF (radio frequency) band of EMF used to transmit data, including 5G, which operates on microwave frequencies.
All electronic devices also emit low-frequency magnetic fields (ELF-EMF) simply to operate. However, the amount of ELF-EMF your phone emits is minimal compared to common sources like power lines, and its biological effects differ significantly from high-frequency RF. When you put your phone on airplane mode, you stop all high-frequency RF, though negligible low-frequency EMF remains. Modern smartphones emit less low-frequency EMF thanks to efficient circuits, but they emit increasingly higher levels of high-frequency RF and microwave radiation to transfer data faster. The 5G standard, for instance, transmits up to 100 times more data than 4G by compressing data into denser, more powerful wave packets.

Yes, a growing body of concrete, large-scale scientific research points to the dangers of excessive EMF exposure. Perhaps the most compelling is a landmark $30 million study conducted by the U.S. National Toxicology Program (NTP). The NTP study found "clear evidence" that exposure to RF radiation used by cell phones caused malignant tumors (schwannomas) in the hearts of male rats, as well as significant increases in DNA damage in brain tissues. These findings were later corroborated by a large-scale study from the Ramazzini Institute, which modeled long-term exposure to cell tower radiation and observed similar increases in tumors.
Crucially, these studies demonstrate that biological harm and DNA damage occur at levels well below the thermal thresholds (heating) that current, outdated government safety regulations rely upon. At RadiArmor, we firmly believe in the cautionary principle. Waiting for slow-moving government agencies to confirm these dangers and update decades-old safety standards is foolish and potentially dangerous. There are simple, proven ways to dramatically lower your exposure right now, and taking proactive steps to protect yourself is the smartest choice.

Since EMF exposure is cumulative, we advise limiting your exposure as much as possible. One of the best habits is keeping your cell phone away from your body and using the speaker function during calls. If you can’t use the speaker, holding your phone even a couple of inches from your ear can lower your EMF exposure by more than half. Additionally, avoid using your phone in poor reception areas; your device will emit much stronger radiation signals as it struggles to connect to a distant cell tower.

While some people seem to show little immediate effect from chronic EMF exposure, others can experience dramatic symptoms even at low levels. Research into the biological effects of EMF has highlighted several common symptoms, particularly regarding sleep disruption.

• Stress, fatigue, and sleeplessness: Peer-reviewed studies have demonstrated that radiofrequency electromagnetic fields (RF-EMF) can directly alter the human electroencephalogram (EEG) during rest and sleep. Furthermore, research indicates that EMF exposure can suppress the body's production of melatonin—the critical hormone that regulates circadian rhythms and promotes deep sleep—leading to chronic insomnia and daytime exhaustion.
• Rashes, burning sensations on the skin, and facial prickling.
• Body pains and muscle aches.
• Burning sensations in the eyes.
• Hazy thinking and brain fog.
• Digestive disorders.

Yes, but it is important to navigate the market carefully due to deceptive practices. One of the most common scams involves EMF blocking stickers or pendants claiming "99% EMF protection." This is highly misleading; the 99% refers to the material itself, NOT the protection the user actually receives. An EMF blocking sticker offers no more protection from ambient radiation than a waterproof sticker would protect you in a rainstorm.
In fact, the California Department of Public Health has warned against such products because they can actually increase your exposure. Because phones are designed to emit signals primarily through their backs, placing an EMF blocker there forces the phone's antenna to work significantly harder, channeling even more radiation out through the front and sides directly into your body. Similarly, products claiming to magically "harmonize" EMF lack any scientific basis.
At RadiArmor, we rely strictly on physics, not pseudoscience. All our products use proprietary, lab-verified EMF blocking materials exceeding 99% shielding capacity, and we clearly post the real-world EMF reduction levels you will experience. Our cases and sleeves are engineered to reduce your actual EMF exposure by 91 to 96 percent, both during use and while carrying it in your pocket.

Yes, RadiArmor’s EMF blocking material provides the exact same high-level protection against 5G as it does against 4G and other high-frequency RF radiation.

No. The anti-radiation membrane is applied exclusively to the front cover. This precision design creates a shield between the radiation and your head or body, while leaving the back of the phone completely unobstructed to receive signals as intended.

Yes, the same 91% EMF reduction applies when the phone is in your pocket, provided you place the phone so the front cover (containing the shielding material) is facing your body. Since your phone constantly emits EMF to stay connected to cell towers, this physical barrier provides continuous protection. However, for absolute maximum protection, we always recommend turning your phone off or putting it in airplane mode when you don't need it.

The only scientifically sound way to block EMF is to physically place a shielding material between your body and the radiation source. Companies claiming near 100% protection are usually citing the raw material's blocking capacity, not what you actually receive. Worse, companies that put shielding in the back of a snap-on case restrict the antenna, which forces the phone to emit stronger radiation and ultimately increases the user's exposure. The wallet style allows us to put the shield exactly where it needs to be—on the front—protecting you without compromising the phone's functionality.

While highly popular on marketplaces like Amazon, pendants and stickers claiming to "harmonize" or "neutralize" EMF are not backed by any legitimate science. Many rely on fake awards or pseudo-scientific "muscle testing" (kinesiology) to prove they work. Muscle testing is easily manipulated by the placebo effect and the power of suggestion, which is why it fails in double-blind studies. In reality, many of these pendants are just pieces of plastic.
Some companies do embed a tiny piece of real EMF blocking material into their stickers, but as mentioned, placing a tiny shield on the back of a phone does not protect you and often increases your overall exposure by forcing the phone to boost its signal. While unscrupulous companies profit from fake magic solutions, the scientific research proving the dangers of EMF is very real. RadiArmor only develops products based on verifiable physics and tested by independent laboratories.

Because there are so many fake products on the market, we strongly encourage our customers to test our cases themselves. To help, we have a video titled “How to test your RadiArmor case” in our video section.
The most critical factor is using the right meter. You need an EMF reader specifically designed to measure high-frequency RF (Radio Frequency) and Microwave (MW) radiation. Standard Gauss or Tesla meters are meant for low-frequency magnetic fields (like power lines) and will not register the high-frequency radiation emitted by your phone. (If you use a TriField Meter, ensure it is set to the Radio/Microwave setting). Furthermore, because cell phones emit massive amounts of RF, you need a meter with a wide dynamic range; otherwise, the meter will simply max out and fail to show the 91% reduction accurately. If you need guidance on testing, please reach out to us.

RadiArmor cases are specifically engineered to deflect EMF from your head during calls and from your vital organs while the phone is in your pocket—areas most vulnerable to radiation. When texting, you can fold the front cover behind the phone, which reduces exposure to the hand holding the device, though the hand actively texting on the screen remains exposed.
