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.

    Mean annual recharge in the Sand Hills of Nebraska (USA) over the 2000-2009 period was estimated at a 1-km spatial resolution as the difference of mean annual precipitation ( P) and evapotranspiration (ET). Monthly P values came from the PRISM dataset, while monthly ET values were derived from...
