What is neutrino?Based on Radioactivity chapter?? How is it used in the radio active field?
Answers
Proton, neutron, and electron are tiny particles that make up atoms. The neutrino is also a tiny elementary particle, but it is not part of the atom. Such particles are also found to exist in nature. Neutrino has a very tiny mass, no charge and spin half. It interacts very weakly with other matter particles. So weakly that every second trillions of neutrinos fall on us and pass through our bodies unnoticed.
Neutrinos come from the sun (solar neutrinos) and other stars, cosmic rays that come from beyond the solar system, and from the Big Bang from which our Universe originated. They can also be produced in the lab.
Neutrinos come in three types or “flavours” – electron neutrino, tau neutrino and muon neutrino.
They can change from one flavor to another as they travel. This process is called neutrino oscillation and is an unusual quantum phenomenon.
Neutrino oscillation was established by Sudbury Neutrino Observatory, Canada, and Super-Kamiokande experiment in Japan. They studied Solar neutrinos, atmospheric neutrinos and man-made neutrinos.
