Alpha rays are used in atomic physics for impact tests; beta rays are used in television tubes, electron microscopes, electron sources, etc.; gamma rays can be used in many high-energy experiments or high-energy weapons.
Ray (ray) by a variety of radionuclides, or atoms, electrons, neutrons and other particles in the energy exchange process emitted, with a specific energy of the particles or photon beam. Common x-rays, alpha rays, beta rays, gamma rays and neutron rays.
A variety of rays, due to the ionization density is different, the biological effect is different, caused by the mutation rate is also different. In order to obtain a higher favorable mutation, it is necessary to choose the appropriate rays, but due to the ray source, equipment conditions and safety and other factors, the most commonly used are γ-rays and x-rays.
Extended information:
Alpha rays can be emitted by a wide range of radioactive substances such as radium. alpha particles can have a kinetic energy of several mega-electron volts. Alpha particles are known to have a positive charge from the direction in which they are deflected in electric and magnetic fields.
Beta rays are negatively charged particles emitted by the decay of radioactive isotopes (e.g., 32P, 35S, etc.). They have a short range and weak penetration in air.
Gamma rays have a strong penetrating ability. When the human body is irradiated by γ-rays, γ-rays can enter the body's interior, and ionization of cells with the body, ionization of ions can erode complex organic molecules, such as proteins, nucleic acids and enzymes.
