A method for determination of 210 Po and 210 Pb in rainwater samples is described. This method was developed to permit measurement of the radionuclides in rainwater samples collected at short time intervals (2 weeks) on a small area (0.5m 2 ) and to give results with the minimum delay. This was achieved by estimating 210 Pb from counts...
Ra, Pb and Po were preconcentrated from seawater samples by addition of a magnetic adsorbent followed by mixing and collection of the adsorbent using a magnet. The magnetic adsorbent is prepared by coating micron sized magnetite particles with manganese dioxide. When yield tracers ( 133 Ba for 226 Ra, 208 Po for 210 Po and stable...
