What difference is between Beta particle and negative charges?

  1. "Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei such as potassium-40. The beta particles emitted are a form of ionizing radiation also known as beta rays. "

    Negative charges also contain electrons, Beta particle are high-energy, high-speed electrons.
    What make beta particle harmful to human? will high-speed electrons be the main cause?
    Does anyone have any suggestions?
    Thanks in advance for any suggestions

  3. Just a question, but are you just trying to get people to do your homework for you?
     
  4. Beta particles are electrons, they're just electrons that originate from nuclear reactions, decays, etc., so we call them beta particles instead.

    They're like a lot of high speed bullets fired at your body.
    Except that they don't leave wounds, and you can't see them, but they damage the body at a sub-cellular level.
     
  6. Thanks everyone very much for suggestions
