The Low Radioactivity Techniques (LRT) workshop series examines topics in low radioactivity materials and techniques, a fundamental aspect of rare event searches.

Topics include global radioactivity measurement and screening facilities, low background counting techniques, purification and contamination control, radon control, comsogenic activation of materials, and backgrounds and simulations for rare event experiments related to dark matter, solar neutrinos, double-beta decay and long half-life phenomena. This conference’s wide scope includes all aspects of the development of low background detectors and techniques.
