Correct Answer: Alpha
Description: Alpha paicles are the most energetic of the 4 types of ionizing radiations. Atoms of different types are known as elements. Elements such as uranium, radium and thorium are unstable. As they change into more stable forms, they release invisible waves of energy called ionizing radiation. 4 main types of ionizing radiations are alpha, beta, gamma and X rays. Alpha paicles are the most energetic of the 4 types of ionizing radiation. 1qswThese are 10 times as harmful as Xrays, beta or gamma rays. It can travel only for a sho distance i.e few inches in air. Alpha paicles lose their energy almost as soon as they collide with anything.
