Alpha radiation is partiles of 42He2+ (2 protons, 2 neutrons, but no electrons).
They are highly ionizing but have low penetration (can cause severe damange to living organisms but can be stopped using a sheet of paper)
If you mean "alpha radiation", that is the result of certain types of radioactive decay.
Yes, alpha radiation is an ionizing radiation.
Alpha (and beta) radiation is "particle radiation" Gamma is electro-magnetic radiation.
No. Decay is the process, radiation is the product.
The first three letters of the greek alphabet. If you mean particles, then ... alpha is a helium nucleolus, beta is an electron, and gamma is electromagnetic radiation.
Yes, alpha radiation is a form of ionizing radiation. It consists of alpha particles, which are helium nuclei composed of two protons and two neutrons. These particles have high energy and can ionize atoms by knocking off electrons from them as they pass through matter.
alpha particles.
An element that has an unstable nucleus and therefore emits alpha, beta and/or gamma radiation.
Alpha radiation is not necessarily the "weakest" radiation. Alpha radiation is the emmanation of helium nuclei, which is two protons and two neutrons. As such, an alpha particle has a mass of 4 and a charge of +2. As a result, it interacts more readily than any of the other forms of radiation. This means that alpha can be stopped with a few inches or air, or even with a sheet of paper. That does not mean, however, that alpha is the least dangerous - if it is ingested, such as into the lungs, it will be in close proximity to sensitive tissues, making it one of the most dangerous forms of radiation. Its penetrating power is certainly the least, but, "weakest", not by a long shot.

Gamma radiation is a type of electromagnetic radiation, whereas alpha and beta radiation are composed of particles. Gamma rays have the shortest wavelength and highest energy, whereas alpha and beta particles are larger and less penetrating. Gamma radiation does not carry an electric charge, while alpha and beta particles do.
