# 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-Jun-10 2010 180 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- DW4 -87.687 30.262 23 0 6.7 0.77 209 4.78 66.5 1.7 166 13.4 nd DW5 -87.686 30.263 22.5 0 18.5 1.4 660 12.7 151 1.04 492 17.7 nd
