摘要：
Fission reactions result in Nd isotope decay products which alter Nd isotopic compositions measured in nuclear debris. Trinitite samples measured by MC-ICP-MS show perturbations of Nd isotopes relative to Nd-142, the only isotope of Nd which is blocked from fission product decay. By measuring Nd-144/Nd-142 and the total number of atoms of Nd-142 in the sample, it is possible to quantify the total number of fissions in nuclear debris, an important signature in post-detonation nuclear forensics.
