It is not clear what is meant by 'beta'. Please rephrase it in a new question.
It's pretty obvious this question is about radioactivity and the beta particles produced by that.
In fact beta particles are not the least penetrating. It is the alpha particles
that penetrate least. That's because they interact easily with atomic nuclei.
Atomic nuclei are positively charged, like alpha particles, causing strong repulsion.
Alpha particles have the least penetrating power compared to gamma rays and beta particles. This is because alpha particles are heavier and more positively charged, which makes them easily absorbed by materials, including skin.
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.
The correct order for decreasing penetrating power of radiation is: gamma > beta > alpha. Gamma radiation is highly penetrating and can pass through most materials, beta radiation can penetrate thin materials, and alpha radiation can be stopped by a piece of paper or even the outer layers of skin.
There are three main types of radiation rays: alpha particles, which are made up of two protons and two neutrons and have low penetrating power; beta particles, which are high-energy electrons or positrons with moderate penetrating power; and gamma rays, which are high-energy electromagnetic radiation with the highest penetrating power.
Gamma rays have the highest penetrating power among alpha, beta, and gamma radiation. They can penetrate the body and various materials easily due to their high energy level.
Alpha particles have the least penetrating power compared to gamma rays and beta particles. This is because alpha particles are heavier and more positively charged, which makes them easily absorbed by materials, including skin.
Beta particles have a very low penetrating power; an aluminium foil of 3-4 mm is a sufficient shielding.
The most penetrating power is for beta particles compared to those given here.

The three types of radiation given off by radioactive substances are alpha particles, beta particles, and gamma rays. Alpha particles are the least penetrating, beta particles are more penetrating than alpha particles, and gamma rays are the most penetrating and dangerous type of radiation.
You throw away the gamma-emitting object due to its high penetrating power, hold the beta-emitting object in your hand as beta radiation can be stopped by skin, and put the alpha-emitting object in your pocket since alpha radiation is the least penetrating and can be stopped by clothing.
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.
Alpha, beta, and gamma radiation have different penetrating abilities due to their difference in energy and interaction with matter. Alpha particles are the least penetrating, as they are heavier and lose energy quickly when passing through material. Beta particles have higher energy and can penetrate more deeply than alpha particles. Gamma rays are the most penetrating as they are electromagnetic radiation with high energy and can pass through most materials.
