Alpha radiation, like any other form of electromagnetic radiation, travels at the speed of light (300 000 000 metres per second)

∙ 12y agoSame as speed of light "C". Gamma Rays are also form of Electro Magnetic Radiations
All EMR incl Light travel at same speed in same medium.
Which is normally approximated to 3 x 10^8 m/s

∙ 12y agoalpha particle is a helium nucleus its speed depends on the amount of energy it was pushed by.
U238 is a strong alpha source clothing will protect you from the alpha radiation
if clothing isn't worn chances are good it wont penetrate your skin

∙ 9y agoThe speed that alpha particles travel is 5 percent the speed of light. The composition of an alpha particle is two protons and two neutrons.
Wiki User
∙ 14y agoI had to look it up.... about 16,000,000 meters per second, which is about 1/19th the speed of light.
Wiki User
∙ 10y agoIt varies, dependent on the energy of the particle. There is no fixed speed through a medium, as is the case with both light and sound.
Hope that helps!

Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
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.
Where could one locate Alpha particles?
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.
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.
Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
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 does a gravitational field affect alpha particles beta particles and gamma radiation?
Gamma rays are a form of electromagnetic radiation, and therefore travel at the speed of light. This would require an extremely massive gravitational field, i.e. an extremely massive object, on the scale of stars. The same goes for beta particles; electrons and positrons, who already travel at nearly the speed of light due to their low mass. Alpha particles, however, due have some mass, and therefore travel at only 5% the speed of light, still fast enough to escape the Earth, but not fast enough to be affected by larger planets, perhaps.
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 is a fast moving beta particle?
Gamma Rays are electromagnetic radiation , just like light is, and it travels the speed of light, 3 x 10^8 m/s . It will always be the fastest because alpha's & beta's are particles with mass and cannot travel the speed of light. The speeds of alpha's & beta's can be different in different situations and do not always have the same speed, like gammas.
How far can alpha particles travel through air?
Just a few inches.
What blocks alpha particles?
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 fast does alpha radiation move?
alpha radiations travel with different speed depending upon the source they are emitted from
What is alpha ionizing?
Alpha particles are helium nuclei emitted with energies of several MeV and travelling at about 5% speed of light. As air molecules take only about 35eV to ionize, highly charged alpha particles are very strongly ionizing.
