# Ra isotopes in groundwater wells. # W. Burnett and B. Mortazavi, PIs # The R denotes duplicate samples. # A, B and corr denote samples that were collected by two Mn-fibers # put in series and the final results corrected for the recovery. # Uncertainties given are +-1 sigma based on counting statistics. # B.D. = below detection. Low yields on some of the shallow wells # were a result of reducing groundwaters attaching the MnO2 fibers. ========================= date_local year yrday_local ------------------------- 6-Mar-12 2012 66 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- TW1 -87.693 30.255 19.6 1.85 5.05 0.49 34.8 1.25 17 0.43 19 2.39 nd TW1A -87.693 30.255 19.6 1.85 4.01 0.41 27.4 1.14 13.5 0.22 15.8 1.89 44.4 TW1B -87.693 30.255 19.6 1.85 2.35 0.34 18.7 1.13 7.52 0.13 6.65 1.8 nd TW1corr -87.693 30.255 19.6 1.85 9.04 0.92 61.7 2.57 30.5 0.5 35.7 4.26 nd TW3 -87.67 30.255 20.1 2.5 3.78 0.45 40 1.21 27.3 0.23 19.1 2.35 nd TW3A -87.67 30.255 20.1 2.5 2.46 0.35 33.5 1.15 22.8 0.09 19.7 2.27 33.8 TW3B -87.67 30.255 20.1 2.5 1.66 0.33 20.9 1.17 15.1 0 10.6 1.91 nd TW3corr -87.67 30.255 20.1 2.5 7.27 1.04 99.1 3.4 67.4 0.27 58.2 6.71 nd TW4 -87.678 30.256 18.9 8.81 6.47 0.67 60.2 1.46 114 1.06 46.8 3.53 nd TW4A -87.678 30.256 18.9 8.81 14 1.11 105 1.94 197 3.46 86.1 4.55 84.1 TW4B -87.678 30.256 18.9 8.81 2.48 0.52 22.3 1.22 31.4 0.75 10 3.15 nd TW4corr -87.678 30.256 18.9 8.81 16.7 1.32 125 2.31 235 4.11 102 5.41 nd TW5 -87.725 30.254 20.6 0.2 2.73 0.27 48.4 1.24 27.9 0.23 41.3 1.97 nd TW5A -87.725 30.254 20.6 0.2 2.64 0.36 43.1 1.51 26.5 0.35 37 2.53 86.8 TW5B -87.725 30.254 20.6 0.2 0.42 0.09 2.45 0.24 3.49 0.9 8.4 2.19 nd TW5corr -87.725 30.254 20.6 0.2 3.04 0.41 49.6 1.74 30.5 0.4 42.6 2.91 nd TW6 -87.725 30.255 21.4 0.07 3.54 0.39 38.2 1.3 32.5 0.86 43.7 2.9 nd TW6A -87.725 30.255 21.4 0.07 3.21 0.4 35.3 1.11 24.4 0.52 40.1 2.62 15.6 TW6B -87.725 30.255 21.4 0.07 2.24 0.35 24.9 1.12 20.6 0.6 26.1 1.97 nd TW6corr -87.725 30.255 21.4 0.07 20.6 2.56 226 7.11 156 3.33 257 16.79 nd TW7 -87.786 30.245 20 0.1 0.88 0.17 9.13 0.61 1.98 0.59 5.05 1.33 nd TW7A -87.786 30.245 20 0.1 0.8 0.18 8.11 0.6 1.35 0.04 5.74 1.5 100 TW7B -87.786 30.245 20 0.1 B.D.
