Web28 de nov. de 2024 · The detection of radioactive emissions is by the ionising effect of radiation on the atoms of matter. An energetic particle or photon that passes through a medium can knock an electron out of an atom in that medium. This process is known as ionisation and it produces charged particles called ions. WebThis radiation is detected by the photomultiplier tubes and shows up as a characteristic ring-like pattern of activity in the array of photomultiplier tubes. As neutrinos can interact with atomic nuclei to produce charged leptons which emit Cherenkov radiation, this pattern can be used to infer direction, energy, and (sometimes) flavor information about incident … Web7. 1.
