    SIGNIFICANCE AND APPLICATION OF NEUTRINOS
    1. A way to monitor nuclear proliferation.
    Neutrinos are produced from radiation, so it might be possible for the International Atomic Energy Agency to use neutrino detectors to monitor which countries are following the treaty on the Non-Proliferation of Nuclear Weapons.

    2. A way to ‘x-ray’ the Earth to find cavities of mineral and oil deposits.

    Neutrinos change the way they spin depending on how far they have traveled and how much matter they have passed through.

    3. Faster global communication.

    These particles can pass through pretty much anything.

    4. A way for scientists to finally detect dark matter.

    The presence of dark matter has still not been directly observed by scientists, but neutrinos could be the missing link. Scientists have theorized that a certain type of neutrino might come from decaying dark matter.

    The IceCube lab has built a neutrino detector in Antarctica that has detected extremely high-energy neutrinos.

    INDIAS POSITION
    India has been among the pioneers in neutrino research, the first of such laboratories having been established in the 1960s. We led neutrino research when our physicists used a gold mine at Kolar in Karnataka to set up what was then the world’s deepest underground laboratory.
