Indications for Increased Cosmic Radiation in the Interplanetary Space,y protons and α-particles. In undisturbed regions a higher and possibly dangerous cosmic ray intensity is expected, but these regions may be at the boundaries of the planetary system. Attention is called to the high intensities that occur after the rare outbursts of solar cosmic rays and to particles trapped in the earth’s magnetic field.
