TOKYO, Aug. 4 (UPI) -- X-ray films that were instrumental in proving that the Aug. 6, 1945, bombing of Hiroshima was atomic have been found after 60 years.
One of the films, found in the research office of the late Japanese physicist Yoshio Nishina in Tokyo, turned black from radiation following the atomic bomb attack on Hiroshima, proving to military officials that the damage was not from an ordinary bomb, the Mainichi Shimbun reported Thursday.
Ryohei Nakane, 84, a former scientist at Riken Institute, found the films while organizing data from the office after earthquake reinforcement work last year.
A list accompanying the seven films showed that five of them were from the Hiroshima Red Cross Hospital. One film from the Hiroshima Red Cross Hospital, which was located less than a mile from ground zero, turned completely black after the bombing, while the others were not significantly affected.
"There were military officials at the time claiming, 'What dropped was not a nuclear bomb,' the evidence have historical value," Nakane said.
