For the most part alpha particles are stopped before passing through the skin.
Alpha particles are the strongest of the three known types of radiation (alpha, beta, & gamma). Although the strongest, the alpha particles are the least penetrating.They do not tend to penetrate any substance.A well-known example is your skin. Alpha particles do not penetrate your skin barrier. However, alpha particles energy is high and is a cause of skin cancer and genetic mutations.
Alpha radiation consists of alpha particles, which are relatively large and heavy, typically composed of two protons and two neutrons. As a result, alpha particles have a low penetrating power and cannot penetrate even a piece of paper or human skin. They are usually stopped by a few centimeters of air or the outer layer of dead skin cells.
1. Alpha Particles are the least penetrating, but do a great deal of radiation damage on the surface of what they hit.2. Beta Particles penetrate to a certain extent depending on their energy.3. Gamma Rays penetrate the most, and a Gamma source requires heavy (lead, etc.) shielding.
Beta particles are smaller and have less mass than alpha particles, which allows them to move faster and penetrate materials more easily. Additionally, beta particles have a lower ionization potential compared to alpha particles, allowing them to interact with materials in a way that allows them to penetrate further.
Ernest Rutherford discovered radiation. Alpha is most harmful is ingested, it cannot penetrate the sign, nor paper or metal or lead, beta is able to penetrate paper and metal, and gamma, the most harmful of the three is able to penetrate paper, metal, lead, and skin. beta can penetrate the skin after a long period of time.

Alpha particles are actually electron-less helium nuclei versus beta particles which are actually electrons, which are much smaller than alpha particles. Therefore, alpha particles' penetrating strength is much smaller than beta particles (a sheet of paper versus a wooden board). Therefore, beta particles will penetrate more into a human body and will do more damage than alpha particles which are usually stopped at the skin.
Alpha: Highly ionising particles that can not penetrate the skin, smoke or most substances. It's only dangerous when inhaled or ingested. Beta: Is slightly less ionising but can penetrate air, layers of skin and paper. It's only slightly more dangerous than Alpha.

If you mean the Alpha radiation, then it can penetrate very little; barely a few cm's in the air as it is a helium nucleus.
Beta particles are smaller and have less mass than alpha particles, which allows them to move faster and penetrate materials more easily. Additionally, beta particles have a lower ionization potential compared to alpha particles, allowing them to interact with materials in a way that allows them to penetrate further.

Alpha radiation can be stopped by a piece of paper, clothing, or human skin. It cannot penetrate the outer layers of the skin, but can be harmful if inhaled or ingested.
False. Alpha particles have a larger mass and charge compared to beta particles, which causes them to interact more strongly with materials. As a result, alpha particles penetrate less deeply into materials compared to beta particles.
Polonium is safe outside the body because it emits alpha particles, which cannot penetrate the outer layer of skin. However, if ingested or inhaled, polonium can be highly toxic due to its high radioactivity and ability to damage cells within the body.
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.
