The Russian Foreign Ministry has released an on-site report on the atomic bombings of Hiroshima and Nagasaki conducted by a team sent by the Soviet Embassy in Tokyo in September 1945.
The Soviet Union was keenly interested in the effects of the new type of weapon.
Studies by experts have also found that the Soviet Union dispatched investigators to the cities just days after the bombings that August, even before U.S. experts got there.
This new report, unveiled Wednesday, was prepared by the embassy and sent to Soviet leader Josef Stalin after a team of three people, including a military attache, visited Hiroshima on Sept. 14, 1945. The city was bombed Aug. 6.
Several days later, the team moved on to Nagasaki, which had been bombed Aug. 9.
The report notes that it was raining heavily on the day the team arrived in Hiroshima. The train station and the town were obliterated with no cover against the rain, it says. Citing witnesses to the blast, the report says a huge explosion followed a flare-up, and many people were subsequently burned to death.
On the radioactive impact on humans, the report, quoting a doctor named Fukuhara, says that some people saw their white blood cell count plummet and bled from the nose and eyes, with their body temperature rising to around 40 degrees. They died three to four days after exposure, it says.
In Nagasaki, the team noted that there were no survivors in areas around ground zero and quoted a witness as saying that a child who had climbed a tree and was covered by thick layers of leaves did not die, while a child nearby on the ground did die.
