Alpha particles have an Atomic Mass number of 4, and a charge of +2. As a result, they are the heaviest and most charged of all the common radioactive decay particles around. This makes them interact with nearly everything.
They can be stopped with only a few inches of air, a sheet of paper, or even your skin. Their danger, however, is that, if you ingest alpha producing material, they can interact most strongly, i.e. ionize, sensitive internal tissues, causing major damage.

∙ 11y agoAlpha particles have a relatively large mass compared to beta particles and gamma rays. They also have a +2 charge.
They attract electrons from the atoms of the material they are attempting to pass through. This slows them greatly. They do 'steal' electrons from those atoms and form helium atoms which increases their size immensely turther making it difficult to pass throught a material.

What materials can alpha radiation go through?
Alpha particles have very little kinetic energy, and are fairly safely stopped by a few centimeters of air or something as thin as a sheet of paper. Of course, they can travel unimpeded through a vacuum.
Clothing and skin will block the majority of the alpha and beta particles from DU materials?
No. Clothing and skin will block alpha, but not beta.
How far can alpha particles from Thorium-232 decay travel in body fluids?
Alpha particles with energies of 4.0 MeV from Thorium-232 decay can travel less than 28 microns in body fluids.
Why do alpha particles travel shorter distance in air than beta particles?
because alfa particle have a tendency to move in air then beta particles
What can stop alpha particles?
A sheet of notebook paper will stop alpha particles. Depending on their energy, alpha particles, which are helium-4 nuclei (two protons and two neutrons), will only travel a few feet in air. Use the link below to learn more.
Why does alpha pass through some materials and not others?
Alpha particles can pass through very few materials. The spacing between nuclei of the material would have to be enormous for an alpha particle to pass through. The passage of alpha particles simply depends on the density of the material.
What can alpha particles can pass through?
Alpha particles can pass through very few substances. It can travel in air but has a range of only a few centimetres.
What gives off alpha particles?
Alpha particles are a type of particle of radiation that is emmited by certain radioactive materials. The materials that give off Alpha particles are called ''Alpha emitters.''
How far can alpha particles travel through air?
Just a few inches.
What do alpha particles leave charged in their path when they travel through matter?
Charged ions
What blocks alpha particles?
A few millimetres of lead.
Alpha particles ejected from the nucleus travel at the speed of light?
No. Alpha particles are helium nuclei; such nuclei have a mass, and can therefore NOT travel at the speed of light.
Why were few alpha particles deflected?
some of alpha particles were deflected through an angle of 90 degree
What materials can alpha radiation go through?
Alpha particles have very little kinetic energy, and are fairly safely stopped by a few centimeters of air or something as thin as a sheet of paper. Of course, they can travel unimpeded through a vacuum.
Can radiation travel through a liquid?
it depends on the type of radiation alpha ((type of)nuclear radiation) can't travel through it for very long Infra red (heat) can but is absorbed by the particles in the water as it goes
Clothing and skin will block the majority of the alpha and beta particles from DU materials?
No. Clothing and skin will block alpha, but not beta.
Can alpha particles pass through the human body?
No
