Gamma radiographies
National french museums and the Musée Guimet of Asitic Arts in Paris have entrusted in 1997 three precious statuettes of khmer divinities to the CEA department of "Applications des rayonnements ionisants" at Saclay. Gamma rays of cobalt-60 are more penetrating than usual X-rays. They show the inside consolidations of one of the statuettes.
