Abstract
For over twenty-five years the DAMA/LIBRA experiment has observed an annual modulation signal that is consistent with a dark matter explanation. This signal is, currently, in tension with the null results observed by other searches that utilize different target detectors. The COSINUS experiment will perform a model-independent cross-check of the DAMA/LIBRA result by using the same target material, NaI crystals, operated as scintillating calorimeters. By measuring both temperature and light the NaI crystals in COSINUS will be able to distinguish between electron and nuclear recoils on an event-by-event basis. However, background events induced by cosmic-rays, environmental radioactivity or the intrinsic contamination of the materials used in the crystal, shielding and infrastructure can pose an issue to any analysis and must be fully understood. We report on the status of the development of the simulation for an active water Cherenkov muon veto, as well as the results of the beginning radiogenic material screening.

Report
In this proceeding authors describe efforts in development of simulation for an active Cherenkov muon veto and present results of first radiopurity measurements of materials used in future experiment.
The manuscript is clearly written and well organised. It is also suitably formatted for publication.
I recommend the manuscript for publication after adding C.L. for the measurements in Table 1.
Requested changes
Please add C.L. for the measurements in Table 1.
