摘要

In this research, the transfer efficiency of micron-sized surrogate actinide particles (Europium-doped Gadolinium Oxysulfide) is measured through gloved thumb press interactions. Results provide evidence that material roughness is more of an influence on particle-to-surface adhesion than material surface energy for the materials used in these experiments. The distribution of particles averaging 25 microns when deposited on glass had a lower average transfer efficiency than the 2.5 microns average particle size grouping, but there is an overlap in uncertainty. This research did not find any evidence that contact time has an effect on particle transport in surface-to-surface interactions.
