April 22, 1960
The AEC agrees to initiate talks with Western European nations in the attempt to control nuclear proliferation through the classification of gas centrifuge technology.
April 9, 1960
Having read the Union Carbide and General Electric reports on gas centrifuges, and taking into account West Germany and The Netherlands’ unwillingness to classify their programs, the AEC looks into other courses of action, including collaboration with the other two nations and even declassifying their own program.
September 16, 1986
In a follow up to their earlier May report, the Lithuanian Academy of Science summarizes levels of radiation detected between April and August of 1986 following the Chernobyl nuclear accident. Atmospheric tests showed a sharp rise in radiation levels in late April, up to 50 times higher than Soviet standards for safe levels of exposure. Levels dropped off in May, with occasional spikes. The report also summarizes tests of food products grown in Lithuania or imported from other Soviet Republics.
May 23, 1986
Report from the Lithuanian Academy of Sciences on radiation levels detected in May 1986 following the Chernobyl nuclear accident. Both atmospheric tests and tests of food products like milk and honey showed elevated levels of radiation and radioactive isotopes which were “dangerous to the health of the population.”
April 26, 1986
The Soviet Minister of Power and Electrification reports on an explosion and fire at the Chernobyl Atomic Power Station in Ukraine. The Soviet Ministry of Heath has determined that "it is not required to take special measures, including the evacuation of the population from the city."
February 21, 1979
Yuri Andropov, then Chairman of the KGB, reports concerns about the Chernobyl nuclear plant. Serious flaws in the construction "might lead to failures and accidents."
March 23, 1960
As West Germany and The Netherlands developed ultra-centrifuges without a classification policy, the AEC discuss ways to keep the technology under wraps without arousing suspicion from the other members of Euratom.
February 26, 1960
A Union Carbide Nuclear Company study to determine how quickly and easily foreign countries could develop and utilize gas centrifuges with the goal of creating nuclear weapon facilities. The study determines that, due to the cheap cost and relatively small size of the centrifuges, even un-industrialized countries such as Cuba could achieve this technology within 8 years if helped by a larger nation.
February 19, 1960
The development of the gas centrifuge method, according to this report, would make production of U-235 (and by extension, nuclear weapons) possible for as many as 20-30 foreign countries. The U.S. is thus forced to consider its strategy for how to limit proliferation despite this new, cheap technology.
December 7, 1959
US Atomic Energy Commission classification director C. L. Marshall explains to international affairs director A. A. Wells that the design for the gas centrifuge must be classified for fear of providing an “unfriendly nation” a low-energy consuming method for “the separation of heavy isotopes…an important part of a [nuclear] weapons program.”
