Lead Equivalence of various materials

This section presents of useful table of lead equivalence for a number of typical building materials. Use caution when using this data as its from pulsating potential x-ray generators with narrow beams. However, from an educational perspective its quite useful when thinking about the design of hospital diagnostic treatment rooms, by looking at where shielding credit could be claimed from the constructional materials used.

Atoms are very special: they like certain particular partners, certain particular directions, and so on. It is the job of physics to analyze why each one wants what it wants.
