Scott, in Encyclopedia of Toxicology (Third Edition), 2014 α Particles α Particles have a positive charge and are identical with helium nuclei, and consist of two protons and two neutrons. They result from the radioactive decay of heavy elements such as radium, thorium, uranium, and plutonium. Ionizing radiation is generated through nuclear reactions, nuclear decay, by very high temperature, or via acceleration of charged particles in electromagnetic fields. Natural sources include the sun, lightning and supernova explosions. Artificial sources include nuclear reactors, particle accelerators, and x-ray tubes.

WebThe movement of the positive or negative charges results in a current – a flow of charges. These currents are anti-parallel for the alpha and beta particles and so result in forces in opposite directions when the particles pass through a magnetic field. WebFeb 16, 2024 · Ionizing radiation is an established risk factor for cancer. Studies involving the irradiation of cells and experimental animals and epidemiological studies of populations that have experienced unusually high levels of radiation exposure for medical or occupational reasons have demonstrated clear links between ionizing radiation and cancer.

Webpositive charge. In excitation, the energy of incoming radiation raises an outer electron to a higher energy state from which it returns very rapidly (10-8s) to its original state emitting a photon of light in the process. The mechanisms involved in the transfer of energy are dependent on the nature of the ionising radiations involved.
