Hydrogen from the sun is generally not deuterium, let alone tritium. Irradiation does not, as a rule, make the irradiated thing radioactive; the hydrogen nuclei aka protons are "radiation" because they're moving very fast and cause damage when they hit things, not because they're inherently different from other protons.
