No, alpha particles are not the most radioactive emission. Gamma rays are more penetrating and more energetic than alpha particles, making them the most dangerous and damaging form of radiation.
Alpha decay has the largest and most damaging particles among the types of radioactive decay. This decay involves the emission of alpha particles, which are made up of two protons and two neutrons and have a relatively high energy level, making them more damaging to living tissues.
Alpha radiation is the least penetrating type of radiation and is easily absorbed by a few centimeters of air, a piece of paper, or even human skin.
The question is unclear. First before what? More likely to occur? I am going to assume the latter... Alpha decay is more likely to occur, when both alpha and beta are possible, because alpha decay removes more binding energy from the nuclide, and the tendency is to reduce energy as quickly as possible.
No, radioactive decay is not a chemical reaction. Radioactive decay is a type of change in the nucleus of an atom that results from instability in that nucleus. And that is a nuclear reaction rather than a chemical one.
Gamma radiation emits high-energy photons, which are electromagnetic particles with no mass or charge. They are the most penetrating type of radiation and are often produced alongside alpha or beta particles during radioactive decay.

alpha decay
The three types of radiation given off by radioactive substances are alpha particles, beta particles, and gamma rays. Alpha particles are the least penetrating, beta particles are more penetrating than alpha particles, and gamma rays are the most penetrating and dangerous type of radiation.
Alpha and beta particles are the same in that changes in unstable atomic nuclei can release alpha particles or can beta particles (depending on the isotope involved), and both are forms of particulate radiation.
Helium (or alpha particles)
Alpha radiation is the least penetrating type of radiation and is easily absorbed by a few centimeters of air, a piece of paper, or even human skin.
Radioactive decay has nothing to do with chemistry and therefore may not be a chemical reaction. But since matter changes its properties (they are even irreversibly) it is considered to be reaction of one (elemental) reactant. Most decay reactions are kinetically of zero order.Different types of radioactive decay include decay by alpha emission (emits an alpha particle, 2 protons and 2 neutrons), Beta - emission, and Beta + emission (positron emission or electron capture).Some radioactive materials also output gamma rays, protons, neutrons, and can decay by fission.
The three types of natural radioactivity are alpha, beta and gamma radiation. Gamma rays are the most energetic, and the hardest to shield against as they do not readily interact with shielding material. Alpha and beta radiation are actually particles. The beta particle is an electron that has been released. Because of its mass, it more readily reacts with shielding material, and so cannot penetrate as far. Alpha particles are the largest and consist of two neutrons and two protons. Shielding is most effective against alpha particles. Your outer layer of dead skin or a T-shirt is generally enough to protect against alpha particles. However, this effectiveness of shielding does not mean that gamma is always the most harmful and alpha the least. The high effectiveness of shielding on alpha particles is due to the fact that they most readily react with the shield (i.e. damage it). This means that if the alpha particle is able to come in contact with living tissue (like the ingestion of radioactive liquids) it will do far more damage than a beta particle or gamma ray.

Alpha decay is more likely to occur, when both alpha and beta are possible, because alpha decay removes more binding energy from the nuclide, and the tendency is to reduce energy as quickly as possible.
Radon is the only naturally occurring radioactive inert gas. Its most stable isotope, radon-222, decays through alpha particle emission. It is produced as a decay product of uranium and thorium in the Earth's crust.
