| Abstract: | A thermal ionization mass spectrometric technique is presented for the detection of 239Pu and 240Pu in sea water, pore water, ocean sediments, sediment trap samples and coral samples. Both sample preparation and purification procedures, as well as the procedure used to detect Pu by mass spectrometry (m.s.), are presented. The m.s. technique proves to be over an order-of-magnitude more sensitive than traditional alpha-counting techniques for the detection of Pu in environmental samples. Also, the ratio of 240Pu/239Pu is obtained with this technique. |
