Tritium is a radioactive form of hydrogen, also known as an isotope, that's produced naturally in the upper atmosphere when gases and cosmic rays collide. When you see the self-illuminating "EXIT" signs in public buildings, tritium creates that luminescent glow.
It’s highly unlikely that you'll ever need tritium, but if you do, a gram is more expensive than many new cars at $30,000 (£23.6k). That's equivalent to $850,500 (£668k) per ounce.
