What is a beta particle made up of?
A beta particle is an electron. Alpha particles consist of two neutrons and two protons, and gamma particles consist of photons.
What is the range of beta particles in the air?
The range of beta particles in the air is up to several hundred feet. Beta particles are emitted by specific types of radioactive nuclei. Potassium-40 is a type of radioactive nuclei that emits beta particles.
Why beta particales are harder to stop than alpha particales?
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.
What correctly describes the charge of beta particles and alpha particles?
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
Can paper shield beta particles?
Beta particles are not stopped by a paper sheet.
What is alpha radiation made of?
Beta particles are made of either electrons (or their opposite particle - positrons). They are emitted from certain atomic nuclei in the process of radioactive decay. Electrons and positrons are considered one of a class of subatomic particles called "Elementary Particles". Elementary particles are believed to have no further substructure, and are therefore made only of energy by the formula E= mc^2.
What is a soft beta particle?
Low energy beta particles, say, from tritium, are called soft beta particles.
What is the charge of beta particles?
Beta Particles have a negative charge,In Beta decay a neutron changes into a proton and a beta particle, an electron.
How can you prevent beta particles?
Thin sheet or plastic may prevent beta particles.
What does it take to stop beta particles with energies up to 13.5Mev?
Materials such as plastic, glass, or water can effectively stop beta particles with energies up to 13.5 MeV by absorbing and slowing down the particles. Thicker layers of these materials are more effective for stopping higher energy beta particles.
Can beta particles pass through aluminum?
Yes, beta particles can pass through aluminum. However, the thickness of the aluminum and the energy of the beta particles will determine how many particles can pass through. Thicker aluminum will block more beta particles compared to thinner aluminum.
What are the properties of alpha particles?
Alpha particles are made up of 2 protons and 2 neutrons, this gives them a strong positive charge. They are slow moving and can be stopped by a sheet of paper or skin. Their charge makes them highly ionising which means that they can damage living tissue if they get inside the body. Beta Particles are made up from electrons it's charge is zero. Their mass is very light (1/1836) . Beta's penetration abilities can travel through Aluminium or a thin sheet of a metal Gamma Particles are made up from a electromagnetic wave it's charge is negative it doesn't have a mass it can travel through Lead
