New portable system for sampling fresh- and ground-waters of low Ra activities. Simultaneous measurement of all four radium isotopes through gamma-spectrometry. Relative uncertainties are 2% to 3% for 226Ra, 228Ra and 224Ra; and <10 % for 223Ra. (228Ra/226Ra) ratios are valuable tracers of water origin in karstic aquifers.
