Rapid determination of strontium-90 in seawater
It is shown that Y 2 O 3 , YF 3 , LaF 3 , and CeF 3 help concentrate 90 Y from seawater. To determine 90 Sr, YF 3 is the best reagent because the effect of interfering lead and thorium radioisotopes is minimum in this case. It is proposed to preconcentrate 210 Bi on PbS to eliminate its interference...

Zusammenfassung: | It is shown that Y

, YF

, LaF

, and CeF
3
help concentrate
90
Y from seawater. To determine
90
Sr, YF
3
is the best reagent because the effect of interfering lead and thorium radioisotopes is minimum in this case. It is proposed to preconcentrate
210
Bi on PbS to eliminate its interference. To determine
90
Sr we measure the Cherenkov radiation of
90
Y concentrated on YF
3
without prior elution. |
