The Geiger counter has long been the audible symbol of radiation, its clicking rate rising with the intensity around the detector. It became especially familiar through coverage and dramatisations of Chernobyl, where the sound came to stand for invisible danger in an abandoned landscape. Online, the effect is now reused far beyond news footage, appearing in urban exploration videos, horror edits, science explainers and gaming clips whenever a scene needs an immediate sense of contamination without any dialogue.
