Hiroshima Beach: X-ray echoes of glassy fallout
Date: May 15, 2019
Author: David Bradley
An X-ray study has proven that tiny glassy particles in the sand on Japan's Motoujina Peninsula came from the fallout of the Hiroshima atomic bomb. Geologist Mario Wannier, who was studying tiny marine life spotted the unexpected in samples of sand from the beach there and hopes his discovery will raise awareness in the scientific community and beyond.
