Kb. Yatsimirskii et Pe. Strizhak, KINETIC DETERMINATION OF CESIUM-137 AND SR-90 RADIONUCLIDES IN WATER, Journal of analytical chemistry, 52(6), 1997, pp. 573-575
A kinetic method for determining low concentrations of cesium-137 and
strontium-90 radionuclides in water was suggested, The method is based
on the fact that these radionuclides have different effects on the re
action rate of ascorbic acid oxidation by Methylene Blue in the presen
ce of copper(II) ions.
