Abstract
The overlying rock of underground laboratories provides excellent radiation shielding necessary for many experiments searching for extremely rare nuclear and astroparticle events. Monte Carlo simulations of HPGe detector background and attenuation of gamma-ray fluxes with different shielding configurations were carried out for an underground laboratory. It has been found that even a small radioactive contamination of the shielding material may increase gamma-ray fluxes in underground laboratory by several orders of magnitude. [ABSTRACT FROM AUTHOR]
