| Abstract: | The volume activity of 90Sr, 137Cs, 238Pu, 239+240Pu, 241Am, and 244Cm in water taken from unorganized water accumulations on lower marks of the Shelter was determined. Separate water accumulations are characterized by their specific radionuclide activity ratios 238Pu/239+240Pu, 241Am/239+240Pu, and 244Cm/241Am. The activity ratios 241Am/239+240Pu and 244Cm/239+240Pu in the water accumulations are 5–10 times higher than in the irradiated fuel of the 4th Unit of the Chernobyl NPP and in lava-like fuel-containing materials. |
