Atmospheric radioactivity and variations in the solar neutrino flux

A calculation of the inventory of positron emitters in the Earth's atmosphere that results from hadronic cascades initiated by galactic cosmic rays and the variation of this source of low-energy neutrinos with the 11-year solar cycle are presented.
