Does Shungite block phone radiation? Popular belief and the current evidence
Shungite phone stickers are very popular. This article sums up what current research says — and doesn't say — about their ability to ‘block radiation’.
“Stick shungite on your phone to reduce radiation” is one of the most common reasons people look for this stone. Before you believe or dismiss it, look at the evidence we have.
Where does the idea come from?
Shungite conducts electricity, and conductive materials can interact with electromagnetic waves — which is why shungite-based materials have been studied for industrial shielding. From there, many people assume a small piece of stone stuck to a phone does the same.
The evidence is very limited
- The study usually cited is a 2003 experiment on mice; its results have not been replicated at a larger scale, and there are no comparable studies in humans.
- Real shielding requires material covering a large enough area; a small sticker cannot surround a device like that.
- Phones need signal to work — if a sticker really blocked it, it would weaken the signal too.
The evidence that a small stone at home protects you from phone and Wi-Fi radiation is very weak.
If you are concerned about electromagnetic radiation
Simpler, better-founded advice: use earphones or the speaker for long calls, don't keep your phone right next to you while sleeping, and follow the guidance of health authorities.

In 1992, scientists first recorded natural fullerenes in a shungite sample. What does that discovery mean, and why shouldn't it be overstated?
Elite shungite has a silvery sheen and is rare and brittle; regular shungite is matte black, durable and easy to craft. Understand the difference to choose the right piece for you.
