This paper describes ultra low-level gamma-ray spectrometry measurements of the 60Co activity distribution inside one 52 mm and one 41 mm thick steel sample. The samples had been exposed to the Hiroshima atomic bomb and were from the Aioi bridge and the Yokogawa bridge. Both samples were measured in a recent study aiming to back up model calculation of Hiroshima dosimetry. The 60Co activity distributions found in this study support the assumptions made in the previous study.
