Abstract
Ultra low-background radiation measurements are essential to several large-scale physics investigations. Assay of solid polymer materials for extremely low levels of radioactive elements, such as uranium, presents challenges. This paper describes an initial investigation into the use of laser ablation with inductively coupled plasma mass spectrometry for screening a solid plastic, polyethylene, for gross uranium levels.
