Alpha decay cannot be stopped. It is an energy release process that only ends when the parent nuclide decays to zero.
If you mean, however, "what stops alpha particles?", then the answer is a few inches of air, a sheet of paper, your skin, etc. This is because alpha particles are heavy, with an Atomic Mass number of four, and charged, with an atomic charge of +2; as a result, they interact with other matter very, very easily.
Normal protection from alpha particles, say when handling new uranium-235, can be as simple as a pair of gloves. The problem with alpha particles comes when you ingest the material that creates them, placing the alpha particles in close proximity to sensitive tissues inside your body. That makes alpha particle emitting material very hazardous, if not properly contained.

Is alpha decay the same as alpha radiation?
No. Decay is the process, radiation is the product.
What type of decay is involved when polonium -214 decays into lead -210?
It is alpha decay. In the process, an alpha particle(He2+) is released. So, it is called alpha decay.
What is the nuclear equation for the decay of Po210 if it undergoes 2 alpha decay then a beta decay followed by another alpha decay.?
92Au 282Xe +13S
Which equation correctly represents the alpha decay of polonium 214?
By alpha decay polonium-214 is transformed in lead-210. Po-214--------------alpha--------------Pb-210
What is alpha decay of mendelevium?
Alpha decay is the loss form the atomic nucleus of an "alpha" particle - that is 2 protons and 2 neutrons (a helium nucleus).
Order gamma decay beta decay and alpha deacy form weakest to strongest?
gamma decay beta decay alpha decay
Is alpha decay the same as alpha radiation?
No. Decay is the process, radiation is the product.
What is the type of radioactive decay in which positive particles are given off?
It's called alpha-decay. The two protons and two neutrons are removed in the form of alpha particles, or helium nuclei.
What is the nuclear equation for the decay of Po210 if it undergoes 2 alpha decay then a beta decay followed by another alpha decay.?
92Au 282Xe +13S

It is alpha decay. In the process, an alpha particle(He2+) is released. So, it is called alpha decay.
What is the heaviest of the forms of radioactive decay is?
I'm pretty sure its alpha.
What is the nuclear equation for the decay of radium 226?
The equation for the alpha decay of 226Ra: 88226Ra --> 86222Rn + 24He The alpha particle is represented as a helium (He) nucleus.
What is the equation for the alpha decay of uranium -237?
The equation for the alpha decay of 233Pu:94233Pu --> 92229U + 24He2+where the alpha particle is represented as a helium nucleus.Note that 233Pu decays by alpha decay with a probability of only 0.12%. The other 99.88% is Beta+ decay.
What is the nuclear equation for the alpha decay of uranium 239?
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
What are the possible products of the alpha decay of uranium-238?
The only possible product of the alpha decay of 92238U is 90234Th.
Which equation correctly represents the alpha decay of polonium 214?
By alpha decay polonium-214 is transformed in lead-210. Po-214--------------alpha--------------Pb-210
The least energetic of the forms of radioactive decay is ______?
