What is the difference between alpha and beta particles?
Alpha particles are released by high mass, proton rich unstable nuclei.
The alpha particle is a helium nucleus; it consists of two protons and two neutrons.
Beta particles are emitted by neutron rich unstable nuclei.
Beta particles are high energy electrons..
How much does a beta particle weigh?
Beta particles have a charge of minus 1, and a mass of about 1/2000th of a proton. This means that beta particles are the same as an electron.
Are alpha particles heavier than neutrons?
Yes 2>1. An alpha particle is identical to the nucleus of a helium molecule, it contains TWO neutrons and two protons. So it has to be heavier than a single neutron.
Which is more dangerous alpha beta or gamma?
Alpha particles are the most harmful internal hazard as compared with gamma rays and beta particles. Radioactive materials that emit alpha and beta particles are most harmful when swallowed, inhaled, absorbed, or injected. Gamma rays are the most harmful external hazard. … Alpha particles cannot penetrate intact skin.
What are the 4 types of radiation?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle.
