Searching for possible hidden chambers in the
Pyramid of the Sun
ICRC-2007, Mérida
Pyramid of the Sun
Archeological problem
- Three man-made tunnels (1920-50): no internal structure.
- Radón (1997) measurements: no large cavities (?)
- Moon Pyramide (+2002 results): Internal structure and large tumb!
