Zusammenfassung
Bone tissues of thirteen deceased persons were analyzed to determine the activity concentration of the radionuclides Ra-228, Th-228, Th-232 and Th-230. The activity ratios enable to assess the post-mortem-interval (PMI). The samples were prepared for analysis by incinerating and pulverizing. Ra-228 was directly detected by gamma-spectrometry. Th-228, Th-230, Th-232 were detected by ...
Bone tissues of thirteen deceased persons were analyzed to determine the activity concentration of the radionuclides Ra-228, Th-228, Th-232 and Th-230. The activity ratios enable to assess the post-mortem-interval (PMI). The samples were prepared for analysis by incinerating and pulverizing. Ra-228 was directly detected by gamma-spectrometry. Th-228, Th-230, Th-232 were detected by alpha-spectrometry after radiochemical purification and electro-deposition. It is shown that the method is principally suited to determine the PMI. A minimum of 300 g (wet weight) of human bone tissue is required for the analysis. Counting times are in the range of one to two weeks.
