Pretty much anything will. A couple of sheets of paper would do it. Alpha radiation is big and bulky compared to other types of radiation. So it can't penetrate objects very far.
Alpha radiation (a Helium atom with two neutrons) is very bulky, and therefore cannot penetrate physical objects easily. A sheet of paper will not absorb, but deflect the alpha particle.
Materials that absorb light typically contain pigments or dyes that are able to absorb certain wavelengths of light. When light hits these materials, the pigments or dyes absorb the light energy, causing the material to appear darker or change color. This absorption of light energy is what allows these materials to absorb light.
Materials such as paper, clothing, and human skin can block alpha particles and prevent their penetration. Additionally, thicker materials like aluminum or lead are more effective at stopping alpha particles.
Radioactive materials such as uranium, radium, and plutonium give off alpha particles during radioactive decay. These particles consist of two protons and two neutrons and have low penetration power, making them easily blocked by materials like paper or skin.

Black materials absorb more heat than white materials because they absorb a wider range of wavelengths, including visible light and infrared radiation. This absorption leads to higher temperatures in black materials compared to white materials, which reflect more light and heat energy.
Alpha particles can pass through very few materials. The spacing between nuclei of the material would have to be enormous for an alpha particle to pass through. The passage of alpha particles simply depends on the density of the material.
Some examples of materials that absorb light include black paper, dark clothing, and certain types of plastics. When light hits these materials, they do not reflect it back but instead absorb it, which is why they appear darker in color.
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.
Examples of materials that absorb water include sponges, paper towels, cotton fabrics, and soil. These materials have porous structures that allow them to soak up and retain water.
