A group of staff members from the Soviet Embassy in Tokyo interviewed Japanese witnesses of the atomic bomb explosions in Hiroshima and Nagasaki. They found that the two bombs wreaked havoc on the bodies of those within a small radius of the explosion; most survivors exhibited severe burns, a decreased white blood cell count, and injuries from broken glass. Witnesses from outside this radius faced less severe injuries, and the Embassy staff note that the Japanese press has been exaggerating the effects of the atomic bomb in order to justify the nation’s unconditional surrender.

Soviet ambassador Yakov Malik introduces a compilation of eyewitness materials and data gathered in the aftermath of the atomic bombings of Hiroshima and Nagasaki. Staff members from the Soviet embassy in Tokyo were sent to survey the explosion sites, speaking personally with survivors and capturing footage of the affected cities.

A cable discussing Molotov's intention to give a speech at the UN about veto powers, atom bombs, and arm reductions. He will offer a proposal from the Soviet delegation calling for universal arms reductions, a ban on the use of atomic energy for warlike aims, and efforts towards global peace and security.

Excerpts from articles on James Byrnes, General Mark W. Clark, Clement Attlee, and US refusal to share technical information about the atomic bomb.

Excerpts from a press conference by James Byrnes on the creation of a Far East Consultative Commission, as well as articles on the atomic bomb, the Council of Foreign Ministers, and a new civilian advisor for Jewish matters appointed by General Eisenhower.

In this document, the "father" of the first Soviet nuclear bomb, Igor Kurchatov, asks the chief of the Soviet ministry of energy, Pervukhin, to help demobilize the Ukranian physicist Veniamin Kelman, who was a fellow of UIPhT before the war. In this note Kurchatov writes about the high quality of the Ukrainian nuclear scientist and about his importance for the development of the Soviet nuclear program. This document once again demonstrates that Ukraine played a significant role in the Soviet military nuclear program.

This famous, de-classified document officially started the Soviet atomic project aimed at producing the nuclear bomb. The second point of this document orders the Ukrainian Academy of Sciences to establish a plan for the project of Uranium enrichment. F. Lange, a scientist from the Ukraine Institute of Physics and Technology, was appointed as head of this project because he worked previously on theoretical aspects of Uranium enrichment.

Report by N.M. Emanuel on the U.S. Castle Bravo test in the Marshall Islands. The report surmises from fallout data that the bomb used a fission-fusion-fission design, and that the bomb contained a larger than normal amount of fissile material which induced a thermonuclear reaction.

The letter describes geographic, safety, and technical considerations taken into account when selecting a test site for the RDS-37 hydrogen bomb. Specifically, the letter highlights that a testing field should be chosen based on the existence of population centers, the terrain, and the main wind patterns.

Resolution outlining the work of the newly established Design Bureau No.11 (KB-11). Atomic bombs are referred to in the resolution as “jet engines S,” in two versions, S-1 and S-2 (abbreviated as RDS-1 and RDS-2). RDS-1 meant the analog of the first U.S. plutonium-239 implosion type atomic bomb tested on 16 July 1945 in New Mexico RDS-2 signified the analog of the uranium-235 gun type bomb exploded over Hiroshima on 6 August 1945.
