22 As is to be expected from the nature of the cleanup and emplacg-~ ment, there is a wide range of concentrations. Summing the **'an with the 73°*2**pu, one arrives at a mean value for the transuranics of 21.4 pCi/g. If there are 12.6 Ci of transuranics in the dome (U.S. Department of Energy 1979) contained in 105,000 cubic yards ¢@f soil and one assumes a density of 1.8 g/cc for the soil, the averade concentration to be expected would be: 12.6 ° 103? 105,000 * 0.76 ° 10° * 1.8 = 87 pCi/g. The soserved and calculated values are in reasonable agreement sin the contribution from the material encased in concrete in the “don hole* at the center of the dome is not considered and neither the ans calculated from the samples nor the estimates made during the clearmip are likely to be very accurate. Water samples taken from two different levels of a hole drill in the dome also were analyzed. The water was filtered through a 0.45 micron filter and both filtrate and filter were analyzed. The me values (in pCi/£}) were as follows: Radionuclide Soluble Particulate zs9tzeeny 0.05 77.8 7%) am 0.005 67 **sr 137 es 331 248 112 146 The transuranics are essentially all asscciated with the particulat fraction and not as available for transport as '*’cs and °*Sr where the greater concentrationa are in the soluble fraction. The mean values (in pCi/£) for samples from the 20-foot level in the two wel outside the dome were as follows: Radionuclide Soluble **7) am *"'Sr ‘#7 es 0.003 225 27 z9sT2eep, 0.142 Particulate 164 59 156 97 Somewhat higher concentrations of all nuclides were found in samples from the 40-foot level in cre well. However, at the present time it is not clear if these radionuclides in the well samples are coming fgon the dome or from the fall-back zone or were present in the soil from other causes such as the work done in preparation for construction o the dome. An artificial beach was constructed for the off loading o the material placed in the dome and it is probable that contaminated soil was used in its construction.
