Which type of radioactivity is associated with charged particles?

The choice of alpha radiation as being associated with charged particles is accurate because alpha particles consist of two protons and two neutrons, making them positively charged. This strong positive charge allows alpha particles to have significant mass, but they also experience a rapid loss of energy in their surroundings, leading to a very limited range of travel and limited penetration ability; they can be stopped by a sheet of paper or even human skin.

Beta radiation, which consists of charged electrons or positrons, is also associated with charged particles. This type of radiation is produced during certain types of radioactive decay (beta decay), in which a neutron in the nucleus converts into a proton or vice versa, emitting a beta particle in the process.

Gamma radiation, on the other hand, is uncharged and composed of high-energy electromagnetic waves. Therefore, while both alpha and beta radiation involve charged particles, gamma rays do not.

Because the question specifically asked for the type associated with charged particles, the choice of alpha radiation is precise, but it's important to note that beta radiation also fits this description. Thus, the reference to only alpha misses the inclusion of beta radiation as another valid option of charged particles. However, if the focus was on the specific types in a singular context, alpha is
