A COST-EFFECTIVE METHOD FOR THE DETERMINATION OF PO-210 AND PB-210 INENVIRONMENTAL MATERIALS

The majority of the methods for the determination of Pb-210 and Po-210 in environmental materials were developed in the 1960s. However, with the advances in technology since that time, particularly in the areas of ion-exchange chromatography and instrumentation, new methods may b e more appropriate to measure these radionuclides in environmental med ia such as foodstuffs. A review was conducted of potentially suitable methods. Four methods were selected for detailed evaluation on the bas is of cost and sensitivity. A cheap, sensitive and simple method is re commended for the analysis of Pb-210 and Po-210 in environmental mater ials.
