The MAJORANA DEMONSTRATOR Neutrinoless Double-Beta Decay Experiment
Figure 13
Estimated background contributions for the -decay search. Backgrounds from natural radioactivity are shown in blue. Cosmogenic activation products are colored red. Green denotes backgrounds from the environment or those introduced during detector assembly. Purple is for μ-induced backgrounds at depth. An upper limit on the negligible background from atmospheric and other neutrinos is shown in orange. The contributions sum to 3.0 cnts/(ROI-t-y) in the MAJORANA DEMONSTRATOR.
