Identification of uranium-bearing particles in swipe samples with fission track method

Abstract

In this study, an advanced method has been developed to identify uranium-bearing particles through fission track and make the particles and fission track detector form a whole. This method can result in the oneto-one correspondence between the fission track and uranium-bearing particles. It is unnecessary to separate the particles from the detector and relocate the particles when they are picked up under microscope. This simple identification is helpful in reducing the loss of particles, which would be picked up and transferred to mass spectrometer for analysis.
