WebWhat is natural radioactivity? Speak to the different types of radiation that an unstable nucleus may emit, and the different types of radiation involved. Why is it important to be … Early researchers found that an electric or magnetic field could split radioactive emissions into three types of beams. The rays were given the names alpha, beta, and gamma, in increasing order of their ability to penetrate matter. Alpha decay is observed only in heavier elements of atomic number 52 (tellurium) and greater, with the exception of beryllium-8 (which decays to two alpha particles). …
