    The only Isotope i know, that emitts beta rays with an energy above 6,2meV is F20 with about 7,1MeV.

    @magnetman33: Oops there's a 2 to much. 128.192.221m/s, a little more than 1/3 of light speed.

    But you are right still, a beta with that much energy is crazy for an element to give off. I thought I read something about an isotope that gives off 20MeV betas but Google gave me nothing so I'm not sure.

    HapyMetal: 1,281,192,221 m/s ? That's over 4x the speed of light lol. Of course an electron isn't going to break that, so realatavistic effects come into play. It's mass would increase instead of its speed so that would account for higher energy. That said I haven't a clue how any of that math works.

    Awesome, +1

    Alpha particles are used in smoke detectors! Also, they can pretty much be blocked with a sheet of paper. Good save! +1

    @sciencedude12398 Every electron in motion is part of the em-spectrum. You are partly right about the kin.energy. Normally a-paticles are emitted with a speed about 15-20000000 m/s so they have an kin.en. of 7,476*10^-13 to 1,329*10^-12 J so you have to accelerate an electr. to 1281192221 m/s, that's about 6,2meV show me a natural beta emitter with that amount of energy.

    beta radiation is not part of the electromagnetic sprectrum even if they were it is not that factor that makes them penetrating its the actual inetic energy and BTW they have more kinetic energy than alpha particles

    alpha particles are not that fast infact they have a very low energy level. the real danger is if they are ingested of breathed in or if an alpha particle emitting particle is ingested or inhaled as i causes damage to weaker tissuse but can be stoped by clothing and/or upper layers of skin
