Alpha particles, which consist of two protons and two neutrons; Beta particles, which consist of one electron; Gamma rays, which is the highest frequency of electromagnetic radiation, has no mass, and is not made up of any subatomic particles. Alpha particles con be stopped by a mere piece of paper; Beta particles can pass through paper but can be stopped by aluminum foil; Gamma rays can pass through paper and aluminum foil, and can only be stopped by lead or concrete.
Alpha radiation, it's force is too weak to even penetrate the outer layer of dead skin. Beta and Gamma radiation can pass through, Beta has trouble passing through clothes whereas Gamma is able to go straight through the body.
Alpha particles are the least penetrating, and are not able to pass through a single sheet of paper. Beta particles can penetrate through a sheet of paper, but not a piece of aluminum. Gamma rays can travel through both paper and aluminum and it takes dense material like lead to stop them or reduce their number. Gamma rays are high energy electromagnetic rays.
Alpha particles can pass through very few substances. It can travel in air but has a range of only a few centimetres.
Depends on how thick the lead is, but beta particles in general don't travel all that far. Of the three types of radiation, gamma (high energy photons) penetrate the most, alpha (helium nuclei) the least, and beta (electrons or positrons) somewhere in the middle. Since most lead jackets stop gamma you can be pretty sure that the lead jackets they use around x-ray machines will stop beta particles.
That depends on the energy of the beta particles and the medium they are passing through. In air beta can travel several inches to several feet. Beta cannot pass through a single layer of aluminum foil.
Beta particles are very small and gamma rays are insubstantial so they can easily pass between or through the atoms of your skin and into your body.
Alpha particles have a high ionizing power beacaue they have a great linear transfer of energy.
Alpha and beta particles are deflected by a magnetic field because they have charge and, as such, are affected by the electromagnetic interaction or force.

Because alpha and beta particles do not have enough power to pass into the body, but they do more damage than gamma rays once they are inside the body.

Alpha particles can pass through very few substances. It can travel in air but has a range of only a few centimetres.
Small particles can pass through the cell membrane by simple diffusion. If the particles are water, the process is given a special name: osmosis.

Gamma rays will always pass through your body. X-rays will pass through normal muscle, fat etc; but are stopped by denser structures like bone. Beta particles (electrons or positrons) depending on their energy will not penetrate the top layer of skin or clothing, but with the highest energy can penetrate about 1cm into tissue. Alpha particles (Helium nuclei) are heavy particles that are stopped by a few centimetres of air and so unless there is contact with a source will not penetrate the skin
