Among the finest Mayan carving to be excavated are three temple door lintels that feature narrative scenes of a queen celebrating the king's anointing by a god.


Radiation protection

Lintels may also be used to reduce scattered radiation in medical applications. For example, Medical linacs operating at high energies will produce activated neutrons which will be scattered outside the treatment bunker maze with a dose rate that depends on the maze cross section. Lintels may be visible or recessed in the roof of the facility, and reduce dose rate in publicly accessible areas by reducing the maze cross section.
