Large scale single-phase liquid argon time projection chambers (LArTPCs) such as DUNE can achieve MeV-scale thresholds, making them sensitive to solar and supernova neutrinos. In this energy region, low energy activity from radiological sources can be a dominant background. LArTPCs can make use of the scintillation light to discriminate against radiological backgrounds. This talk will present rejection methods exploiting the scintillation light in LArTPCs. We studied a range of detector configurations and rejection approaches based on the properties of the light (pulse shape discrimination) and/or on the detector design.
