WebJan 1, 2004 · Solar photons with energies from ∼100 keV to ∼20 MeV, including all nuclear gamma-ray lines, stop primarily in the thick rear segment alone. The intense 3–100 keV X-ray fluxes that usually accompany large γ-ray line flares are absorbed by the front segment, so the rear segment will always count at moderate rates.
