GoKawiilSNO+ Detector in Canada Tracks Geoneutrinos to Map Earth's Interior
Deep inside the Creighton mine at Snolab in Sudbury, Canada, researchers operate the SNO+ neutrino detector, a water-shielded sphere filled with liquid scintillator and lined with thousands of light sensors. The device is designed to catch geoneutrinos, rare particles emitted by radioactive decay inside the Earth, by isolating itself from cosmic radiation and surface contamination through extreme cleanliness protocols including showers and radiation-free clothing for anyone entering.
