Alpha radiation can be stopped by a sheet of paper, beta by a sheet of aluminum foil gamma... several feet of lead. Positrons are 'anti-electrons' and so it would annihilate itself in contact with an electron from normal metal.

∙ 12y agomostly yes because aluminum is not that dense but it depends on the thickness of the aluminum, really thick aluminum would not be penetrated, but i am not sure on any figures.
his a nice animation (http://www.darvill.Clara.net/nucrad/images/penetration.gif) that shows how gamma rays (the green line at the bottom) only gets stopped by the more dense lead

How would you list alpha partcles beta particles and gamma rays in order of increasing penetrating power?
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.
Define the three types of Radiation alpha particles beta particles gamma particles and list the name of the scientist who discovered it?
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.
What ype of radiation ionzing is less penetrating?
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.
What are the components of natural radiation in order from least to most penetrating?
Alpha particles, which consist of two protons and two neutrons; Beta particles, which consist of one electron; Gamma rays, which is the highest frequency of electromagnetic radiation, has no mass, and is not made up of any subatomic particles. Alpha particles con be stopped by a mere piece of paper; Beta particles can pass through paper but can be stopped by aluminum foil; Gamma rays can pass through paper and aluminum foil, and can only be stopped by lead or concrete.
What is Alpha radiation stopped by?
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.
What would penetrate a car door made of aluminum?
gamma ray
What is a gamma particles penetration ability?
gamma particles have high penetration power they can easily penetrate several feet of steel walls.
Can alpha penetrate aluminum but not concrete?
Alpha particles do not penetrate much. They are stopped by a few inches of air. They do not penetrate a piece of paper well, and are stopped by aluminum and concrete. Beta particles can penetrate better, but are stopped by rather thin pieces of aluminum. High energy beta particles are shielded with plastics, wood, or water. Gamma rays are best absorbed by atoms with heavy nuclei. Neutrons are usually either absorbed by atoms or moderated to the point of having little energy. Unlike the other emissions, neutrons have a half life, which is a little less than fifteen minutes.

Do red light penetrate most than gamma why?
Red light does not penetrate more than gamma rays.
What stops beta particles from traveling?
Aluminium
What kind of gamma ray can penetrate solids?
Gamma rays are gamma rays are gamma rays.
Which radioactive particle can be stopped by a regular sheet of notebook paper?
Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead. Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead.
