Activation of materials is known to cause background events in underground experiments that may affect the sensitivity of these experiments to rare event searches. The most common source of activation is the exposure of materials to cosmic rays at the surface of the Earth but other various sources of neutrons may also be dangerous. Different computer codes provide estimates of the production...

Neutrino-less double beta (0νββ) decay experiments probe for such rare events that the suppression and understanding of backgrounds are major experimental concerns. Cosmogenic induced isotopes have the potential to be a major background for such experiments. For the MAJORANA DEMONSTRATOR Experiment 76Ge isotope is used as both detector and source. The isotopes 68Ge and 60Co are cosmogenically...
