Are the glow colors radioactive? - Martinis Arctic Fruit Store

Q: Are the glow colors radioactive?

Absolutely not! Nothing inside the paint is radioactive. Glow pigments work by absorbing energy from light. Sunlight, room light or UV light excites tiny electrons inside the pigment into a higher energy state. They don't stay there forever, so over time they slowly fall back to their normal state and release the stored energy as visible light. That's why the shirt glows after the lights go out. No batteries. No electricity. No radioactivity. Just physics. If you'd like to dive deeper: https://en.wikipedia.org/wiki/Strontium_aluminate
