Collectively they are often referred to as radiation from a radioactive substance.
When atoms decay, they emit three types of radiation, alpha, beta and gamma. The alpha and beta radiation consist of actual matter that shoots off the atom, while gamma rays are electromagnetic waves. All three kinds of radiation are potentially hazardous to living tissue, but some more than others, as will be explained later on. The first type of radiation, Alpha, consists of two neutrons and two protons bound together to the nucleus of a Helium atom. Though the least powerful of the three types of radiation, alpha particles are nonetheless the most densely ionizing of the three.
Gamma radiation, unlike alpha or beta, does not consist of any particles, X-rays are similar to gamma radiation, with the primary difference being that they.

Radiation Detectors. Three types of radioation - Alpha, Beta, Gamma There are three primary types of radiation: Alpha - these are fast moving helium atoms. They have high energy, typically in the MeV range, but due to their large mass, they are stopped by just a few inches of air, or a piece of paper. Beta - these are fast moving electrons. They typically have energies in the range of a few hundred keV to several MeV.
Radioactivity is the process in which unstable atomic nuclei spontaneously decompose to form nuclei with a higher stability by the release of energetic sub atomic particles. The above definition tells us that radioactivity is a random or spontaneous naturally occurring process. The process cannot be influenced by external factors such as heat, pressure or exposure to a magnetic field. This is not to be confused with the radiation that arises from nuclear fission in nuclear power stations. Here the fission is not spontaneous but is triggered in a nuclear reactor by the bombardment of high energy neutrons.
Alpha-, Beta- and Gamma-Ray Spectroscopy Volume 1 offers a comprehensive account of radioactivity and related low-energy phenomena. It summarizes progress in the field of alpha-, beta- and gamma-ray spectroscopy, including the discovery of the non-conservation of parity, as well as new experimental methods that elucidate the processes of weak interactions in general and beta-decay in particular. Comprised of 14 chapters, the book presents experimental methods and theoretical discussions and calculations to maintain the link between experiment and theory. It begins with a discussion of the interaction of electrons and alpha particles with matter. The book explains the elastic scattering of electrons by atomic nuclei and the interaction between gamma-radiation and matter. It then introduces topic on beta-ray spectrometer theory and design and crystal diffraction spectroscopy of nuclear gamma rays.
How Radiation Sickness Works
All three were named by a New Zealand-born physicist named Ernest Rutherford in the early part of the 20th century. - When radiation of high enough energy strikes another atom , it strips away an electron. The resulting positively charged atom is called an ion , which explains why high energy radiation is called ionizing radiation.
Three Types of Radiation: The Properties and Uses of Alpha, Beta, and Gamma Radiation
An unstable atomic nuclei loss its energy by emitting radiations such as alpha rays, beta rays and gamma rays by a process called radioactive decay. A substance with such an unstable nucleus is called the radioactive substance. The particles produced by radioactive decay, i. Alpha rays:. They are also called alpha particles.
Many nuclei are radioactive; that is, they decompose by emitting particles and in doing so, become a different nucleus. In our studies up to this point, atoms of one element were unable to change into different elements. That is because in all other types of changes we have talked about only the electrons were changing. In these changes, the nucleus, which contains the protons which dictate which element an atom is, is changing. All nuclei with 84 or more protons are radioactive and elements with less than 84 protons have both stable and unstable isotopes. All of these elements can go through nuclear changes and turn into different elements. In natural radioactive decay, three common emissions occur.
