Neutrino detection is a challenging process due to their weak interaction with matter, requiring large and sensitive detectors often located deep underground or underwater to minimize background noise. These detectors utilize various methods such as Cherenkov radiation, scintillation, and radiochemical techniques to capture the rare interactions of neutrinos with other particles.

Cherenkov Radiation occurs when a charged particle, such as an electron, travels through a dielectric medium at a speed greater than the phase velocity of light in that medium, emitting a characteristic blue glow. This phenomenon is analogous to a sonic boom and is utilized in various applications, including nuclear reactors and particle detectors, to identify high-energy particles.

Scintillation refers to the rapid fluctuation in the brightness or position of a distant star or other astronomical object, caused by the Earth's atmosphere. This phenomenon is analogous to the twinkling of stars and can also affect radio waves, impacting satellite and GPS signals.
