Electron radiation

Electron radiation is a stream of free electrons. E-radiation is emitted in radioactive decay of nuclei of the atoms of the substance (beta decay) as beta rays. The intensity of electron beta radiation depends on the type and quantity of radioactive substances. E-radiation of high energy and intensity receive through special installations - charged particle accelerators (see). Electron radiation is used in electronic therapy (see).

Electron radiation - a flow of charged particles - electrons. E-radiation is emitted in radioactive decay of nuclei of atoms (beta decay) as beta rays. Because radioactive beta decay simultaneously with an electron (see) is formed neutrino, electron radiation spectrum is continuous. The maximum energy of the electrons not exceed several million electron volts. The intensity of electron beta radiation depends on the type and quantity of radioactive substances.
Electron radiation can also be obtained with the help of special facilities - accelerators of charged particles (see). On electron accelerators can be obtained beams of particles with energies in the tens and hundreds of million electron volts or higher.
With the passage of a beam of fast electrons through matter scattering of electrons, ionization of atoms of matter and radiation of photons (bremsstrahlung). The ability of the electron radiation to cause ionization of atoms is used for its registration. The same effect is based application of electron beams in engineering and medicine. Widely used methods of electronic therapy based on the use of electron beams, accelerator-produced. Electronic therapy has an important advantage over other types of radiation therapy in connection with the possibility to control the depth of penetration of electrons in a fabric by changing the energy of the electrons. The use of beams of fast electrons in therapy allows to reduce in comparison with the V-ray irradiation of healthy tissues lying on the way to the tumor, because the maximum ionization is created near the end of the path of the electron.
