The clicking of a Geiger counter is heard when Cpt. Price and his team of four locate a package in the Call of Duty 4: Modern Warfare level, "Crew Expendable". It was popularized, though, in the Call of Duty 4: Modern Warfare level duo: "All Ghillied Up" and "One Shot, One Kill" where there are radioactive patches scattered around Pripyat, Ukraine and the player must carefully avoid them while completing their objective. It is also used to locate the nuke in Call of Duty: Modern Warfare: Mobilized in the campaign level "Needle in a Haystack".
