Understanding Radon Gas Decay: How Half-Life Functions and Why Density Halves Every 20 cm If you’ve ever studied radon gas or encountered the term “half-life” in scientific contexts, you may have noticed a fundamental principle: density halves every 20 centimeters, a decay pattern with a halflife of 20 cm. But what does this really mean, how does it apply, and why is it important in radiation health, geology, and environmental safety? --- ### What is Radon and Its Natural Decay?
