What is the ionising power of alpha?

Answer 1

alpha particle is the heaviest(compared to gama and beta particle).....it has got haish positive charge and moves with a speed lower compared to beta and gama particle and therefore it ionizies the particles around it as it moves in its path

Answer 2

First of all, "Alpha" refers to atomic particles. Alpha particles are NOT nuclear radiation. The worst of the ionizing radiations are neutrons, and Gamma radiation. A piece of notebook paper is enough to stop Alpha particles dead in their tracks. A book, about 2 inches thick, stops Beta particles. Gamma, 1 foot of lead, or 3 feet of concrete. About the same for neutrons.

Alpha radiation is an ionizing radiation.

Answer 3

Because, like Alabama Man, alpha particles are big, strong, and active! An alpha particle is about 16,000 times more massive than an electron and has twice their charge, but of opposite sign. Therefore, as alpha particles plow through a material, they're ripping electrons off of the atoms and molecules within that material left and right without breaking a sweat, ionizing all of those poor atoms and molecules in the process.

Answer 4

Between Alpha, Beta and Gamma, Alpha has the strongest ionising power but the weakest penetration power as it is stopped by a sheet of paper.

Answer 5

The higher collision rate of alpha produces a greater concentration of ionisation (over a short range)

Answer 6

very very ionising but can be stopped very easily
