Because there are considerable difference between the three, with respect to electric charge, mass, and energy.
Alpha rays are helium nuclei, two protons and two neutrons, an atomic mass number of 4, and a charge of +2. Beta rays are electrons or, in some cases, positrons, an atomic mass number of 1 / 1854, and a charge of -1, or +1 for the positron.
The most penetrating power is for beta particles compared to those given here.
Gamma radiation is more penetrating and is able to travel further through matter compared to alpha radiation. Alpha radiation, on the other hand, is absorbed quickly by even a sheet of paper or skin due to its larger mass and charge, making it less penetrating than gamma radiation.
Alpha particles have very weak penetrating power. They are heavy and charged, so they interact strongly with matter, causing ionization and losing energy quickly. Therefore, alpha particles can generally only travel a few centimeters in air and can be easily stopped by a sheet of paper or skin.
Alpha radiation is the weakest. It can be stopped by a piece of paper and posses no threat to any human tissue. Beta radiation is strong, but still not lethal. It can be stopped by most clothing or fabrics. Gamma radiation is the strongest. It can only be stopped by lead. It posses great harm to tissue that it comes in contact with.
Alpha particles are positively charged. They have low penetrating power but high ionizing power.
Alpha particles have the lowest ionizing ability due to their relatively large size and low penetrating power. Beta particles have medium ionizing ability as they are smaller and more penetrating than alpha particles. Gamma rays have the highest ionizing ability because they are electromagnetic waves that can penetrate deeply into materials, causing damage to biological tissues.
Alpha radiation is the least ionizing type of nuclear radiation. It consists of positively charged alpha particles, which have low penetrating power and are easily stopped by a sheet of paper or clothing.
Beta and alpha are two different things. Beta has negative charges, Alpha has positive. Now the thing is that their ionizing powers also differ. Alpha has extremely HIGH ionizing power whereas Beta has comparatively less (gamma has no ionizing power). Basically alpha ionizes the particles around it very fast and there fore it cannot proceed further into the material, whereas Beta has less ionizing power and can therefore travel farther into the material as the particles around it don't get ionized as fast as alpha. (this is the same reason why gamma has such high penetration power, because it doesn't ionize substances at all). Basically alpha has least penetration power as the ionizing power is most, Beta has medium ionizing and penetration power (compared to alpha and gamma) Gamma has most penetration power as it's ionizing power is least. Hope that answers the question.
it keeps no records of wrong

alpha ray.
Alpha radiation has the weakest penetrating power among the three common types of radiation (alpha, beta, gamma). Alpha particles can be stopped by a sheet of paper or a few centimeters of air, making them less penetrating but more damaging if inhaled or ingested.
The ionizing power of radiation is related to its ability to create charged particles (ions) as it passes through matter, which can cause damage to biological tissues. Penetrating power, on the other hand, refers to how deeply radiation can travel through a material before being absorbed. Generally, radiation with high ionizing power tends to have lower penetrating power, and vice versa.
Alpha particles have a positive charge and weak penetrating power. They can be stopped by a sheet of paper or a few centimeters of air.
Alpha particles have the highest ionizing power because they are large, positively charged particles that interact strongly with electrons in matter. Due to their size and charge, alpha particles have a high probability of colliding with and ionizing atoms in their path, resulting in the transfer of energy and the creation of ion pairs.
No, alpha particles have the highest ionizing power due to their larger size and positive charge. Cathode rays have less ionizing power compared to alpha particles, but they still have the ability to ionize atoms and molecules when they interact with them.
