  2. Beta particle - Wikipedia

    en.wikipedia.org/wiki/Beta_particle

    Beta particles can be used to treat health conditions such as eye and bone cancer and are also used as tracers. Strontium-90 is the material most commonly used to produce beta particles. Beta particles are also used in quality control to test the thickness of an item, such as paper, coming through a system of rollers. Some of the beta radiation ...

  3. Common beta emitters - Wikipedia

    en.wikipedia.org/wiki/Common_beta_emitters

    Tritium is a low-energy beta emitter commonly used as a radiotracer in research and in traser [check spelling] self-powered lightings. The half-life of tritium is 12.3 years. The electrons from beta emission from tritium are so low in energy (average decay energy 5.7 keV) that a Geiger counter cannot be used to detect them. An advantage of the ...

  4. Radiation - Wikipedia

    en.wikipedia.org/wiki/Radiation

    Beta radiation from linac accelerators is far more energetic and penetrating than natural beta radiation. It is sometimes used therapeutically in radiotherapy to treat superficial tumors. Beta-plus (β +) radiation is the emission of positrons, which are the antimatter form of electrons. When a positron slows to speeds similar to those of ...

  5. Beta decay - Wikipedia

    en.wikipedia.org/wiki/Beta_decay

    The two types of beta decay are known as beta minus and beta plus.In beta minus (β −) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino; while in beta plus (β +) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β + decay is also known as positron emission.

  6. Ionizing radiation - Wikipedia

    en.wikipedia.org/wiki/Ionizing_radiation

    The penetrating power of x-ray, gamma, beta, and positron radiation is used for medical imaging, nondestructive testing, and a variety of industrial gauges. Radioactive tracers are used in medical and industrial applications, as well as biological and radiation chemistry. Alpha radiation is used in static eliminators and smoke detectors.

  7. Radiochemistry - Wikipedia

    en.wikipedia.org/wiki/Radiochemistry

    Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being inactive as the isotopes are stable).

  8. Radioactive tracer - Wikipedia

    en.wikipedia.org/wiki/Radioactive_tracer

    It decays by beta-decay with a half-life of 87.51 days. It is used to label the sulfur-containing amino-acids methionine and cysteine. When a sulfur atom replaces an oxygen atom in a phosphate group on a nucleotide a thiophosphate is produced, so 35 S can also be used to trace a phosphate group.

  9. Radionuclide - Wikipedia

    en.wikipedia.org/wiki/Radionuclide

    In food preservation, radiation is used to stop the sprouting of root crops after harvesting, to kill parasites and pests, and to control the ripening of stored fruit and vegetables. Food irradiation usually uses beta-decaying nuclides with strong gamma emissions like cobalt-60 or caesium-137.
