Left to right - alpha particles, gamma rays and beta particles. When alpha particles or beta particles or gamma photons hit atoms they knock off negative electrons causing ionisation, that is, in this case, the formation of positive ions. Check of this article is requested. That means that nuclear changes involve almost a million times more energy per atom than chemical changes!

17.3: Types of Radioactivity: Alpha, Beta, and Gamma Decay
Equivalent dose is often expressed in terms of millionths of a sievert, or micro-sievert. With each collision they lose some of their energy in ionising the air molecule until eventually they give up all of their energy and are absorbed. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. However, its short flight knocks about , electrons out of the surrounding atoms. Gamma decay Gamma decay occurs because the nucleus of an atom is at too high an energy state.
Forces and fields: Alpha, beta and gamma - Penetrating power
In most cases, radiation will damage a single or very small number of cells by breaking the cell wall or otherwise preventing a cell from reproducing. Various species of quarks combine in specific ways to form protons and neutrons, in each case taking exactly three quarks to make the composite particle. Therefore the effects of its interaction ionization are much more spread out. Beta decay In beta decay, a particle is emitted from the nucleus of an atom. Because of the large mass of the alpha particle, it has the highest ionizing power and the greatest ability to damage tissue. When studying nuclear reactions in general, there is typically little information or concern about the chemical state of the radioactive isotopes, because because the electrons from the electron cloud are not directly involved in the nuclear reaction in contrast to chemical reactions.
Complete the following nuclear reaction by filling in the missing particle. The alpha and beta radiation consist of actual matter that shoots off the atom, while gamma rays are electromagnetic waves. Radioactivity basically means the emition of particles known as alpha,beta and gamma these are the radiations that come out of a nucleus and make the nucleus stable! You can think of different isotopes of an atom being different "versions" of that atom. This reaction is an alpha decay.
