Alpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle. Because of the large mass of the alpha particle, it has the highest ionizing power and the greatest ability to damage tissue.

Mar 19, 2020 · 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.
Alpha particles and beta particles are both types of ionizing radiation emitted during radioactive decay. However, they differ in terms of their composition and penetrating power. Alpha particles consist of two protons and two neutrons, making them identical to helium nuclei.
May 13, 2017 · Alpha particles are helium nuclei and beta particles are fast moving electrons. Alpha particles are released when a nucleus is too heavy - this means there are so many protons and neutrons in the nucleus that the nucleus becomes unstable.

As previously indicated, matter gives off energy (radiation) in two basic physical forms. One form of radiation is pure energy with no weight. This form of radiation — known as electromagnetic radiation — is like vibrating or pulsating rays or "waves" of electrical and magnetic energy. Familiar types of electromagnetic radiation include sunlight (c...
As previously indicated, large unstable atoms become more stable by emitting radiation to get rid of excess atomic energy (radioactivity). This radiation can be emitted in the form of positively charged alpha particles, negatively charged beta particles, gamma rays, or x-rays, as explained below. Through this process — called radioactive decay — ra...
In some elements, the nucleus can split as a result of absorbing an additional neutron, through a process called nuclear fission. Such elements are called fissile materials. One particularly notable fissile material is uranium-235. This is the isotope that is used as fuel in commercial nuclear power plants. When a nucleus fissions, it causes three ...
Radiation can be either ionizingor non-ionizing, depending on how it affects matter. Non-ionizing radiation includes visible light, heat, radar, microwaves, and radio waves. This type of radiation deposits energy in the materials through which it passes, but it does not have sufficient energy to break molecular bonds or remove electrons from atoms....
Alpha particlesare charged particles, which are emitted from naturally occurring materials (such as uranium, thorium, and radium) and man-made elements (such as plutonium and americium). These alpha emitters are primarily used (in very small amounts) in items such as smoke detectors. In general, alpha particles have a very limited ability to penetr...
Beta particles, which are similiar to electrons, are emitted from naturally occurring materials (such as strontium-90). Such beta emitters are used in medical applications, such as treating eye disease. In general, beta particles are lighter than alpha particles, and they generally have a greater ability to penetrate other materials. As a result, t...
Gamma rays and x-raysconsist of high-energy waves that can travel great distances at the speed of light and generally have a great ability to penetrate other materials. For that reason, gamma rays (such as from cobalt-60) are often used in medical applications to treat cancer and sterilize medical instruments. Similarly, x-rays are typically used t...
Neutrons are high-speed nuclear particles that have an exceptional ability to penetrate other materials. Of the five types of ionizing radiation discussed here, neutrons are the only one that can make objects radioactive. This process, called neutron activation, produces many of the radioactive sources that are used in medical, academic, and indust...
1: Gamma radiation. 2: Mass determines penetration depth, charge determines ionization potential. In this article, we explore the properties of radioactive alpha, beta, and gamma particles, their danger, and how to stop them.

Oct 1, 2024 · Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay.
