does helium 4 or tritium decay fast by gamma rays?

this isnt a hw question just asking because I am confused as to if I am correct or not

    Only nuclear fusion or fission processes produce gamma rays.

    Helium-4 is stable, it does not decay. Same with Helium-3, completely stable, non-radioactive. It's rarer than Helium-4 though, but that's only because of the stellar processes that produce each type of helium.

    Tritium, aka Hydrogen-3, decays by beta decay, produces no gamma rays. Just produces an electron or positron plus a neutrino, no photons.

      Actually, it's not correct that gamma rays are only produced by fusion or fission.
      Gamma rays were discovered by observing the natural decay of Radium.  Long before fusion or fission were even hypothesized.

    I'm not sure what you mean by "by gamma-rays".

    If you mean "by being bombarded with gamma-rays"  the answer is no. No method to speed up radio-active decay has been found - except shooting neutrons into nuclei like happens in nuclear reactors and atom-bombs

    Helium-4 does not decay.  It is stable.

    Tritium decays by beta emission.

    No.

    Tritium decays into Helium-3 by beta decay, with a half life of a bit over 12 years.

    Helium-4 is a stable isotope, and has no known fast decay mechanism.

      Correct, but the question was about He-4
      H-1 and H-2 are also stable.

    Helium 4 is *stable*.
