A new 2,400 L liquid scintillator has been produced for the COSINE-100 Upgrade, which is under construction at Yemilab for the next phase of the COSINE dark matter experiment phase. The linear-alkyl-benzene-based scintillator is designed to serve as a veto for NaI(Tl) crystal targets and a separate platform for rare event searches. We measured radioactivities of the liquid scintillator using a custom-made 445 mL cylindrical Teflon container equipped with two 3-inch photomultiplier tubes. Analyses show activity levels of 0.091 ± 0.042 mBq/kg for 238U and 0.012 ± 0.007 mBq/kg for 232Th. © 2025 IOP Publishing Ltd and Sissa Medialab.
