Is a small or large decay constant best for protection against gamma radiation? Hint: Calculate half thickness.

Example: Decay constants for Pb, Al, water, and Fe are 0.77, 0.16, 107, and 0.44. Which is better for radiation shielding?

The larger the decay constant, the fewer penetrations of the material.
