![]() We theoretically calculated the activity on the path that arose during the explosion of an atomic bomb of the same yield as the hydrogen bomb in Bikini (14 Megatons according to official data).The activities on the path were produced by fission fragments which came about as a result of the primary.Our report considers only that activity which was produced by fission fragments. ![]() It is necessary to take into consideration that part of the was produced by the neutrons formed during a thermonuclear reaction. How reach the fallout path? Primarily, due to fissile material from an atomic charge (either uranium or plutonium), which is utilized for the purpose of the initiation of a thermonuclear reaction. This assessment may be compared with the outcomes observed in the Bikini region. Thus, we set ourselves on a task to develop an assessment of the radioactive contamination which is to be expected following the 1 March 1954 explosion at Bikini, if it would be possible to calculate it from the data on our own nuclear weapons tests. This formula allows us to assess the dose levels on the path for a device, if radiation levels for any path are known.Īs is known, such dosage assessments assume great significance in the period before the conducting of new tests, and they provide a foundation for various practical activities regarding the provision of security for any humans and animals that may be found in the vicinity of the radioactive cloud’s path. Consequently, the scaling of the radioactive fallout path formula, proposed by N.N Semenov, was evaluated. Such information makes an assessment possible of the nature of the exploding materials, and particularly-.Īssessments of such nature were made possible in 1954 when N.N Semenov, N.A Dmitriev, V.N Rodigin, and N.M Emanuel, produced a summary of the data on the radioactive contamination which was produced as a consequence of detonations of the RDS device at the UP-2 (see report no. However, the information published in print is of interest for other reasons as well. These reports particularly emphasize the high levels of gamma radiation along the fallout path, and in relation to this, the dangers which may arise after the detonation of hydrogen bombs. Official international sources (“A report by the United States Atomic Energy Commission on the effects of high-yield nuclear explosions” from 15 February 1955) as well as the press have recently given much attention to the question of the radioactive contamination created after the explosion of the hydrogen bomb at Bikini on 1 March 1954. See ‘hydrogen bomb’.“Regarding the Nature of the fallout path of the Hydrogen Bomb detonated on 1 March 1954 at Bikini. with its high share of other plutonium Plutonium - the 94th element in the classification of elemen. plutonium Plutonium - the 94th element in the classification of elemen. and a multiple of this impact velocity is necessary for reactor System used to initiate, maintain and control a fission chai.

The highly developed weapon technology in the nuclear weapon countries partly enables lower values, e.g. material is required for a nuclear blasting charge, e.g. A minimum mass of fission See 'nuclear fission'. material was fissioned in one millionth of a second. In each case about 1 kg fission See 'nuclear fission'. The bombs dropped on Hiroshima (U-235 bomb) and Nagasaki (Pu-239 bomb) had an explosive energy Ability to do work or diffuse heat. ![]() The explosive force of a nuclear weapon is indicated in kilotonnes (kt) or megatonnes (Mt) of TNT equivalents (TNT (trinitrotoluol) is a chemical explosive). released during the fission See 'nuclear fission'.
