Even easier to form. ;D

Cosmic rays will be almost entirely from overhead, being effectively shielded by the bulk of the earth. High altitude sources will have more (less atmospheric shielding). If you live near sources of uranium or thorium your background could have some fairly obvious directionality. Your shield might be different types and thickness for different directions to reflect the energy spectra and direction of the various sources.

Yup. And, it is fairly impractical to shield from cosmic rays. The energies are insane, although most of them collide with a molecule in the atmosphere first, and produce showers of lesser-energy particles at lower altitudes. If you want to completey shield against them, you have to go down into a mine. The usual technique is a fast scintillator above your detector that produces a veto of the main detector.
