Fig.1 (IMAGE) Osaka University Caption The results of “snap shot” radiography using laser-induced neutrons and X-rays simultaneously. (Left) Photograph of the samples: Nickel metal hydride battery (Ni-MH), nickel cadmium battery (Ni-Cd), and boron carbide powder (B<sub>2</sub>C). (Center) X-ray radiography, where B<sub>2</sub>C is transparent to X-rays. (Right) Neutron radiography. The Ni-Cd can be distinguished from the Ni-MH based on the darkness of the shadow. In addition, low transmittance was observed for B<sub>2</sub>C. These results highlight the advantage of neutrons, which can identify materials that are transparent to X-rays. Credit © 2021 A.
