Alpha particles have a range of a few centimeters in air and are stopped by a sheet of paper or human skin. Their penetration range in tissue is limited to a few cells.

How far can alpha particles travel through air?

Just a few inches.


How far can alpha particles from Thorium-232 travel in body fluids?

An alpha particle with energy of 4.0 MeV from Thorium-232 decay can travel less than 28 microns in body fluids.


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.


How far does alpha travel in air?

About 10cm.


How far can alpha particles from Thorium-232 decay travel in body fluids?

Alpha particles from Thorium-232 decay have very low penetration power and can typically travel only a few centimeters in body fluids. This means that the surrounding tissues within a short distance of the particle's source would be affected by its radiation.


Do beta particles travel further than alpha particles?

Yes, beta particles typically travel further than alpha particles because they have a higher energy level. Alpha particles are heavier and more charged, so they interact with matter more readily and have a shorter range. Beta particles have less mass and charge, allowing them to penetrate further.


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.


Why beta particales are harder to stop than alpha particales?

Beta particles have a higher penetrating ability compared to alpha particles because they are smaller and have higher energy levels. This allows beta particles to travel further and penetrate deeper into materials, making them harder to stop than alpha particles. Additionally, beta particles can travel faster than alpha particles, increasing their ability to penetrate materials.

Alpha particles ejected from the nucleus travel at the speed of light?

Alpha particles are emitted from the nucleus at high speeds, typically around 5-10% of the speed of light. They move with such energy due to the strong repulsive force between the positively charged alpha particle and the remaining nucleus.


Why do alpha particles travel shorter distance in air than beta particles?

Alpha particles are larger and heavier than beta particles, so they interact more readily with air molecules through collisions. This causes alpha particles to lose their energy more quickly and travel shorter distances in air compared to beta particles, which are smaller and lighter. Additionally, alpha particles have a higher ionization potential, leading to more interactions with air molecules and a shorter range in air.
