Understanding Radioactive Decay
⚛️ What is Half-Life?
The half-life of a radioactive substance is the time required for half of the radioactive atoms in a sample to undergo decay. It's a constant characteristic of each radioactive isotope, unaffected by physical or chemical conditions.
📉 Exponential Decay Formula
Radioactive decay follows exponential decay: N(t) = N₀ × (1/2)^(t/T), where N(t) is remaining amount, N₀ is initial amount, t is elapsed time, and T is half-life period. This formula describes how quantities decrease over time.
🔢 Decay Constant Relationship
Half-life (T) and decay constant (λ) are related by T = ln(2)/λ ≈ 0.693/λ. The decay constant represents the probability of decay per unit time, providing an alternative mathematical description of radioactive decay.
🧪 Practical Applications
Half-life calculations are essential in radiocarbon dating, nuclear medicine, radiation therapy, environmental monitoring, nuclear power generation, archaeological dating, and pharmaceutical drug metabolism studies.
⏱️ Multiple Half-Lives
After one half-life: 50% remains. After two half-lives: 25% remains. After three half-lives: 12.5% remains. The pattern continues with each half-life reducing the remaining quantity by half.
