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.
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.
How far does an alpha particle travel?
This depends on their energy. An alpha particle that comes from nuclear decay is usually only able to travel a short distance, a few centimeters, through air. Alpha particles as cosmic rays, however, are much more energetic, and can penetrate quite deeply, even through many meters of solid shielding. These can penetrate the atmosphere.
What blocks alpha particles?
A few millimetres of lead.
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.
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.

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.
How far does alpha travel in air?
About 10cm.

A few millimetres of lead.
What do alpha particles leave charged in their path when they travel through matter?
Charged ions
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
How far will alpha travel?
a few centimeters deepending on the energy
Can neutrons travel as far through matter as alpha and beta particles can?
Alpha particles are actually a nucleus of a helium atom, consisting of a 2 protons and 2 neutrons, and therefore significantly larger than one single neutron. Beta particles on the other hand is electrons, much smaller than the neutron. The particle's size determine it's energy, and probability of avoiding collision.Cut short,Beta particles go long the longest of the three.Neutron shorter.Alpha particles can't penetrate a piece of paper. Travel shortest.
