Investigating the Radiopurity of Lithium Molybdate for Rare Event Searches

High radiopurity materials are essential for rare event searches such as dark matter and neutrinoless double beta decay. Gamma ray spectroscopy with high purity germanium detectors is one of the most important ways to screen materials for radiopurity. In this poster, we describe a high-purity germanium detector setup in above-ground lab and report on the sensitivity to contamination of interest as ⁴⁰K, ²³⁸U, and ²³²Th. We will further report on the radiopurity of an off-the-shelf sample of Lithium Molybdate measured with this setup. This material is potentially of interest for neutrinoless double beta decay searches as CUPID and AMORE.
