# 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 ------------------------- 7-Sep-11 2011 250 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- TW1 -87.693 30.255 27.1 4.7 4.04 0.41 29.1 1.3 17.4 0.27 18.8 3.37 nd TW5 -87.725 30.254 27.1 0.3 3.07 0.3 89.2 2.18 25.1 0.2 33.7 3.08 nd
