Accelerator mass spectrometry (AMS) is presently the most sensitive technique for the environmental measurement of radionuclides with half-lives greater than about 5000 years. Traditionally, it has been used principally for light elements, of which the most familiar example is 14C. With some modifications, however, it may also be applied to elements as heavy as the actinides, and in particular to 239,240,244Pu and 236U. Here, the principles and methodology of heavy-element AMS are described,...[Show more]
