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.
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 can be stopped by a few centimeters of air. At normal atmospheric pressure, about 3-4 inches of air is sufficient to absorb alpha particles and reduce their energy to a harmless level.
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 exhibit a definite range in matter because they are relatively heavy and charged helium nuclei that interact strongly with the surrounding material through electromagnetic forces. As they travel through matter, the alpha particles lose energy by ionizing atoms and causing excitation, leading to collisions that eventually slow them down and stop them. This process gives rise to a specific range that alpha particles can penetrate before their energy is dissipated.
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
Paper can stop alpha particles because paper has a higher density compared to air, which makes it more likely that the alpha particles will collide with the atoms in the paper, losing energy and stopping their movement. Additionally, the small size of alpha particles means they are easily absorbed by the materials they come into contact with.
They stop.

Simple, after 1950: to avoid any internal irradiation with alpha particles.
Alpha decay is the type of radioactive decay in which positive particles, specifically alpha particles, are emitted. These alpha particles consist of two protons and two neutrons bound together, giving them a positive charge.
some of alpha particles were deflected through an angle of 90 degree
