The operation of INO will have no release of radioactive or toxic substances.The observatory will be located underground so as to provide adequate shielding to the neutrino detector from cosmic background radiation.The observatory is to be built jointly with the Department of Atomic Energy and the Department of Science and Technology. The Tata Institute of Fundamental Research is the nodal institution.INO Project is aimed at building a world-class underground laboratory with a rock cover to conduct basic research on neutrino.The overburden provided by the Earth matter is transparent to neutrinos whereas most background from cosmic rays is substantially reduced depending on the depth at which the detector is located. This is the reason most neutrino observatories are located deep inside the Earth’s surface. The background from cosmic rays (which interact much more readily than neutrinos) and natural radioactivity will make it almost impossible to detect them on the surface of the Earth. Neutrinos are notoriously difficult to detect in a laboratory because of their extremely weak interaction with matter. Why should the laboratory be situated underground? This is possible with neutrinos since they are the only particles which can probe the deep interiors of the Earth. Another important possible application of neutrinos is in the area of neutrino tomograph of the earth, that is detailed investigation of the structure of the Earth from core on wards. Neutrinos hold the key to several important and fundamental questions on the origin of the Universe and the energy production in stars. Hence, a neutrino is about 17 billion times lighter than a neutron. The mass of a neutron is 1.67×10 to the power -27 kg while the mass of a neutrino is of the order of 1×10 to the power -37kg.Neutrinos are the least harmful of all elementary particles, as they almost never react with solid bodies. ![]() Mcdonald for discovering neutrino oscillations demonstrating that neutrinos have mass. In 2015, the Nobel prize in physics was awarded to Takaaki Kajita and Arthur B.“Electron neutrino” is associated with the electron.
