Table 7 Uranium concentrations, beta gamma dose rate at 30 cm (μGyh-1) and activity ratios (where measured) in surface soil river sediment and water samples (μgL-1) from Fallujah, Iraq

From: Uranium and other contaminants in hair from the parents of children with congenital anomalies in Fallujah, Iraq

Sample a Beta/gamma b Uranium mgkg -1 c U238/U235
Soil 1 150 0.857, 0.685, 1.033 129
Soil 2 120 0.164, 0.231, 0.252 132

Soil 6 130 1.44, 1.51, 1.51 129
BP Horizon Oil   0.070, 0.073, 0.073 138

  1. Three separate aliquots were taken from each soil sample and results are shown. Limit of Detection was 0.002 mgkg-1. As a check on the ion exchange method, the Uranium atom ratio from the deep oil from the BP Horizon Macondo oil spill was run with the Fallujah soil samples.
  2. a nGyh-1; b mean of three runs is tabulated for each of three aliquots; LOD, U-235 = 0.0007; c Natural ratio is 137.88; these measurements are derived from counts using the ion-exchange extracted Uranium solutions. 95% CI limits for Natural Uranium Ratio are 132.1 < Ratio < 144.1, Values below 132.1 are thus enriched, above 144.1 depleted with p < 0.05. NA = not assessed.
