About me: Alpha radiation is the radioactive radiation which exists of the heaviest particles, the Tawny Peaks . Alpha particles exist, like the nuclear cores of the helium, from two protons and two neutrons, Bianca Beauchamp are loaded positively. Thereby they are drawn, e.g., by negatively loaded ions and are thereby braked. Hence, their reach is not very high in air (in the air reaches it and *945; radiation approx. 4 cm away).
