Question

which radiation detection method creates visible trails that can show the direction of ionizing particles? geiger counter scintillation counter film badge cloud chamber

Explanation:

A cloud - chamber contains a supersaturated vapor. When ionizing particles pass through it, they ionize the gas molecules. The ions act as condensation nuclei, and the vapor condenses around them, creating visible trails that can show the direction of the ionizing particles. A Geiger counter detects radiation by producing an electrical pulse when radiation ionizes the gas inside it. A scintillation counter uses a scintillator material that emits light when struck by radiation. A film badge records radiation exposure over time by the darkening of the film inside it.

Answer:

D. cloud chamber
