A RADIOCHEMICAL method 1 has been developed for the determination of cæsium-137 in urine. Acidified urine containing cæsium carrier is passed through a column of ammonium phosphomolybdate mixed with ...
A NUMBER of methods have been proposed for determining very low concentrations of cæsium-137 in sea-water by γ-ray spectrometry. The sodium potassium cobaltinitrite method 1,2 and the nickel ...
