The Search for the lost "Battle of Anghiari": Lost_Leonardo-018
Testing the neutron backscatterer at the ENEA facility near Rome, Italy. They are testing the device on a mock brick wall to see whether it can pick up hydrogen (organic material) for the search for Da Vinci's lost Battle of Anghiari. In the background is a nuclear reactor that currently is not being used in this particular test, but might be used in future tests.
