The LSC held in the Palacio de Congresos of Jaca the LRT 2019. The Low Radioactivity Techniques (LRT) workshop series examines topics in low radioactivity materials and techniques, a fundamental aspect of rare event searches. The main goal of this workshop series is to bring together experts in this field for presentations and discussion covering broadly the issues of low radioactivity techniques. The intention is to foster and continue the collaboration and resource sharing required for new generations of detectors to be developed at underground facilities. This edition of the workshop was be hosted by the Laboratorio Subterráneo de Canfranc (LSC), which is the second largest deep underground scientific laboratory in Europe.
