Abstract

In the field of nuclear waste management is the determination of difficult to measure isotopes important for the isotopic nuclide inventory in disposal material. Accelerator mass spectrometry propose a new precise and reliable way for the quantification of the radioactive material by the means of direct atom counting. For the radiological characterization of radioactive material, the reference nuclides Co-60 or Eu-152 are normally used, because they are relatively easy to measure by gamma ray spectroscopy. The disadvantages are the relatively short half-lives and in the case of reactor concrete they are produced at trace elements. In addition, the technique of projectile X-ray AMS (PXAMS) offers the opportunity to measure medium mass isotopes like Ni-63 and Sr-90, by the measurement of characteristic X-rays. We investigated the X-ray production yields for different target materials in a projectile ion energy range of 0.35 MeV/u to 1.80 MeV/u for the determination of attainable sensitivities.
