Disclaimer: This is a simplified engineering model for educational purposes. Real-world outcomes depend on many additional factors: angle of impact, soil composition, building construction quality, secondary effects (fire, collapse), fragment patterns, and more. The Kinney-Graham blast model and linear attenuation approximations used here are simplifications of complex phenomena. Always follow Home Front Command instructions. No shelter guarantees survival against a direct hit from a heavy ballistic missile.
