The possible sources analyzed up to now for the neutron flux background at the Gran Sasso National Laboratory are the natural radioactivity in the rock, the concrete, as well as the induced part coming from interaction of cosmic ray muons with the rock or the detector material itself. Water was considered only as moderator in concrete, due to its variable concentration and its radioactivity as additional source for neutron flux modulation. Therefore, the water-rock interaction and its spatial-temporal variation induced by hydrological pattern of the Gran Sasso aquifer are taken into account.

Abstract
The possible sources analyzed up to now for the neutron flux background at the Gran Sasso National Laboratory are the natural radioactivity in the rock, the concrete, as well as the induced part coming from interaction of cosmic ray muons with the rock or the detector material itself. Water was considered only as moderator in concrete, due to its variable concentration and its radioactivity as additional source for neutron flux modulation. Therefore, the water-rock interaction and its spatial-temporal variation induced by hydrological pattern of the Gran Sasso aquifer are taken into account.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
