Demonstration of 151Sm analysis using Trinity nuclear debris samples

Journal Article · · Journal of Radioanalytical and Nuclear Chemistry
Here, the long-lived fission product 151Sm (T1/2 ≈ 90 y) present in archived dissolved Trinity nuclear test debris samples was analyzed using liquid scintillation counting and the results were compared to the expected values based upon historical analysis results. The measured 151Sm activities were found to agree with the expected values within experimental error. This demonstration validates the use of this technique in situations where the sample is too old for traditional shorter half-life radioactive fission product signatures such as 99Mo (T1/2 = 2.75 d), 97Zr (T1/2 = 16.7 h), 147Nd (T1/2 = 10.98 d), and 153Sm (T1/2 = 46.3 h), or too dilute for determining fissions through stable isotope ratio measurements.
