The volume activity of 3H, 90Sr, 137Cs, 234U, 235U, 238U, 238Pu, 239+240Pu, and 241Am in ground waters from observation holes 1-G-6-G in the north section of the Shelter local area of the Chernobyl Nuclear Power Plant (CNPP) was measured. The distribution of radionuclides in the suspension fractions of the ground waters was evaluated. The main contribution to the pollution of ground waters with uranium is due to natural uranium isotopes: 234,235,238U. The activity ratios of 238Pu, 239+240Pu, and 241Am in ground waters are similar to those in the spent fuel of 4th CNPP block. [ABSTRACT FROM AUTHOR] |
