Relationship between radium isotopes and their chemical analogues in a hot spring area in Taiwan
A gamma-ray spectrometry was used to measure radium isotopes in a radium-enriched hot spring area. The activity of 224Ra was highly correlated with 228Ra in water caused by their same chemical behavior and the or...

Application of ICP-QMS for the determination of ultratrace-levels of 226Ra in geothermal water and sediment samples
A rapid, accurate and less labor intensive approach to determining 226Ra in environmental samples was examined; this utilized quadrupole-based inductively coupled plasma mass spectrometry (ICP-QMS). The procedure...

Variations of U/Th-series nuclides with associated chemical factors in the hot spring area of northern Taiwan
The relationship of the activity ratios (ARs) of U/Th-series nuclides and associated factors (pH, Eh, and the concentrations of Cl- and SO4 2-) in the hot spring area of Taipei were determined. The contents of U ...
