Presets
Gamma rays are not stopped abruptly — they are attenuated exponentially, I = I₀·e^(−μx). The half-value layer is the thickness that cuts intensity in half, and it takes about ten of them to reach 0.1%. Dense, high-atomic-number materials like lead have the largest μ, which is why they make the most compact shields.
