# Ra isotopes in groundwater wells. # W. Burnett and B. Mortazavi, PIs # The R denotes duplicate samples. # A,e collected benote samples that werin series a by two Mn-fibers # put ected for thd 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 ------------------------- 29-Nov-11 2011 333 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- TW1A -87.693 30.255 21.7 4.63 6.18 0.52 50.3 1.16 37.4 0.97 47.2 2.85 43 TW1B -87.693 30.255 21.7 4.63 3.71 0.4 27.3 0.99 21.3 0.86 22.6 2.5 nd TW1corr -87.693 30.255 21.7 4.63 14.4 1.21 117 2.7 -87 2.26 110 6.63 nd TW4 -87.678 30.256 21.5 6.78 7.99 0.66 59.4 1.33 93.3 0.84 39.9 2.9 nd TW5 -87.725 30.254 22.4 0.2 1.63 0.24 45.3 0.9 19.2 0.62 24.1 2.71 nd TW7 -87.786 30.245 21.6 0.11 1.1 0.25 10.9 0.56 2.46 0.07 11.2 2.83 nd
