Gran Sasso, Italy

Large amounts of gallium have also been used to study radiation given off by the sun. In experiments conducted at the National Laboratory at Gran Sasso, Italy, containers holding more than 33 short tons (30 metric tons) of gallium were used to detect and measure various types of radiation originating from the sun. These experiments were conducted from 1991 to 1997 and from 1998 to 2002.
