oct 20, 2017 barium and radium are members of the alkaline-earth metal group. while barium is an abundant element in the earths crustal rocks 340 mg kg 1, radium occurs in nature only in trace amounts 0.1 ng kg 1 .radium has no stable isotopes and the most abundant radium isotope is 226 ra with a half-life of 1600 years. radium-226 is part of the 238 u decay chain and decays to the short,barium sulfate jamming pump thickening filtering,i would guess that you have formed barium sulfate essentially barite which is pretty insoluble, and not too easy to remove. this is probably a result of mixing of two different waters one rich in barium rich is a relative term, but over time it can add up, probably representative of reducing conditions with a low sulfate concentration and a second more oxidized sulfate bearing water.
