    It's Alpha that is the most dangerous as it is the least penetrating. ie when it gets in, it won't get out and can kill and damage various cells by ionising them.
    The other 2 are dangerous 2, just not in the same way and capacity as alpha radiation.

    Alpha is the most ionising but least penetrating. Gamma is least ionising but most penetrating. Both are very dangerous and can cause mutations. Beta is kind of in the middle and can still be dangerous.

    Alpha is the most ionizing, beta is in the middle and gamma is the least.

    In the body, an alpha source is the most dangerous, as most/all of the radiation will be absorbed by body tissue. A gamma source will be less damaging as it is significantly less ionizing, so most of the radiation will pass straight through your body. Beta radiation is somewhere in the middle.

    Considering other times, it also affects the distance it travels through air - alpha radiation won't pass through more than a metre or so of air and can be stopped by just a piece of paper. However, gamma radiation can travel hundreds of metres before interacting with an atom :yep:

    Alpha is the most ionising (dangerous) inside the body as it can't get out nor travel very far.

    Gamma is arguably the least ionising inside the body as it passes straight out; however, it can travel very, very far and it takes a lot to stop it.

    Beta is somewhere in the middle. It's also (technically) the most ionising outside of the body as Alpha doesn't travel very far and is stopped very easily, and gamma radiation is too weak.

    Alpha particles don't travel very far because they're the most ionising. i.e. they're the most likely to interact with particles.
