Actually the longer the wavelength, the greater the penetrating power. Cosmic rays penetrate because the are particles, not EM radiation. The shorter wavelengths have a stronger effect because they carry more energy.

In general the shorter the wavelength, the greater the penetrating power.
Cosmic rays go through everything. Electromagneitc radiation is a continuous
spectrum from radio to cosmic rays. Attenuation is a matter of thickness and
specific properties; light will travel through miles of fiber optics, but be
stopped by a sheet of aluminum.
