Radiation, flow of atomic and subatomic particles and of waves, such as those that characterize heat rays, light rays, and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation.
24 Μαΐ 2018 · This chapter describes what the radiation is; chemical action of radiation; historical developments of researches on radiation chemistry; and type, characteristics, and sources of radiations. Radiation is the flow of energetic electromagnetic wave or particle in the space.
21 Μαρ 2024 · Gamma Radiation. Frequently, gamma ray production accompanies nuclear reactions of all types. In the alpha decay of \(\ce{U}\)-238, two gamma rays of different energies are emitted in addition to the alpha particle. \[\ce{_{92}^{238}U} \rightarrow \ce{_2^4He} + \ce{_{90}^{234}Th} + 2 \ce{_0^0\gamma} \nonumber \]
A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively.
This chapter introduces radiation chemistry by discussing the sources of ionizing radiation (radionuclide sources, machine sources), absorption of radiation energy, techniques used in radiation chemistry research, and methods of absorbed energy (absorbed dose) measurements.
19 Μαρ 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.
Radiation chemistry is defined as the study of chemical changes induced by ionizing radiation in gases, liquids, or solids. It plays a crucial role in various fields such as medicine, nuclear technology, and industrial applications.
