摘要：
The results of investigations of the radiation characteristics of graphite samples taken front the masonry in two commercial uranium-graphite reactors at the Mayak Industrial Association are presented. The specific activity of alpha, beta, and gamma emitters present in the graphite in different parts of the masonry, including cells located next to the damaged cell, is determined. The specific activity of the main product Of activation Co-60 is 10(2)-10(4) Bq/g. The concentration of Cs-137 in the graphite is higher than that of any other fission product (the specific activity in the cells located next to the damaged cell is 10(4)-10(6) Bq/g). 244 On makes the largest contribution to the total activity of transuranium elements; its activity it? one sample was 2.10(7) Bq/g. More than 90% of the activity of the masonry graphite is due to 14 C. The outer and inner surfaces of the graphite bricks are most highly contaminated with radionuclides. The results obtined are the basis for the high estimated content of radionuclides it? the entire graphite masonry for each reactor.
