Activity levels of short-lived radium isotope (223Ra) along 17 beach transects in Baltic Sea

This dataset contains activity levels of 223Ra (short-lived radium isotope) in groundwater, surface water and river samples collected along the Baltic Sea coastline. This data was used in radium mass balance models that were applied along 17 beach transects in the Baltic Sea. Activity levels were measured using a Delayed Coincedence Counter (RaDeCC). Details of column names in the file are as follows: Sample_ID : ID of the sample Sample_Type : Source of the sample denoted by SW, GW, and RIV. SW refers to surface water sample, GW and RIV are used to denote groundwater and river samples, respectively. Latitude : Latitudinal coordinate of the location (DD) Longitude : Longitudinal coordinate of the location (DD) Ra223_dpm/100L : Activity level of 223-radium in units of dpm/100L Ra223_unc_dpm/100L : Associated uncertainty in the measurement of 223-radium activity levels, expressed as dpm/100L
