    A quick answer for the moment.



    Some background


    I think NASA/Goddard is the primary agency for collecting data on solar radiation. They do a lot of research into the effect of radiation on systems and personnel.

    It looks like the local density is about 10 particles/cc. Electrons and protons (alphas) are electrically neutral on a macroscopic scale. The coulomb forces simply enforce electrical neutrality.
