  9. Health threat from cosmic rays - Wikipedia

    en.wikipedia.org/wiki/Health_threat_from_cosmic_rays

    The health threat depends on the flux, energy spectrum, and nuclear composition of the radiation. The flux and energy spectrum depend on a variety of factors: short-term solar weather, long-term trends (such as an apparent increase since the 1950s [28]), and position in the Sun's magnetic field. These factors are incompletely understood.
