Alpha radiation consists of physical particles ... helium nuclei ...with relatively
low energy. Beta radiation consists of a stream of electrons ... much smaller
than alpha particles. Gamma rays are electromagnetic ... the electromagnetic
rays with the highest frequency, the shortest wavelength, and the greatest
energy.
Are relatively large. They are Helium nuclei [Helium atoms stripped of their electrons] As a result they interact often with the matter they pass through often and their energy is rapidly dissipated.
relatively large size and double positive charge
Alpha radiation
A lot of things, but I think you might be referring to which form of radiation since this is the classic answer as to what would stop Alpha radiation. Furthermore tinfoil would stop alpha and beta radiation and lead would stop alpha, beta and gamma radiation.
Alpha radiation is the easiest to shield, only requiring a few inches of air or a sheet of paper. This is because alpha has a mass of four amu and a charge of +2, making it interact with nearly everything.
A zinc sulfide scintillator probe is used to detect alpha radiation. The scintillator probe is just sensitive to alpha radiation.
alpha radiation :)
Alpha radiation
The type of radiation that is easiest to shield are alpha particles. They are also the least harmful. Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus.

If by ionising radiation you mean alpha radiation (the most ionising out of alpha, beta and gamma radiation) then about a millimetre of paper would stop it. alpha radiation ionises the molecules of anything it reaches, but can pass through very few things due to its immense ionising power. This includes human tissue, but in all honesty, a large dose of alpha radiation wouldn't do human tissue alot of good. In short, almost any material can stop ionising radiation.
Yes, alpha radiation is an ionizing radiation.
paper and flesh
Yes, alpha radiation is an ionizing radiation.
To stop radiation leaking out. Alpha and Beta types of radiation will be stopped by the concrete
Alpha (and beta) radiation is "particle radiation" Gamma is electro-magnetic radiation.
It is only deadly if ingested. The skin will stop alpha radiation. It does not have much penetrating power. When inside the body it can cause cellular damage which can lead to cancer.

No. Decay is the process, radiation is the product.
