摘要：
The graphite masonry from decommissioned commercial uranium-graphite reactors is contaminated with radionuclides and is a significant fraction of the radioactive wastes from the nuclear industry. Information about the composition and degree of contamination of the graphite is needed to choose methods and time periods for handling this graphite. The results of investigations performed on I-1, EI-2, and ADE-3 reactors at the Siberian Chemical Combine in 1996-2001 are presented in this paper Analysis of a large number of samples made it possible to construct a detailed picture of the contamination of the masonry, study the distribution of the radionuclides of different origin in the masonry, construct schemes for making estimates, and estimate the content of certain radionuclides, including C-14, H-3, Sr-90, (241)AM, (244)cm, Pu238-241, Cs-137,Cs-134, and Co-60.
