Never mind.... I found the answer...

Wilson cloud chamber. The Wilson cloud chamber was one of the earliest tools used by radiochemists. Radioactive particles cannot be seen even with the most powerful microscope, so the Wilson cloud chamber allows chemists to view decay particles indirectly. By changing the pressure inside a glass dome, a water vapor cloud is created. When charged particles pass through the chamber, they leave tracks of their paths. A study of their direction, speed, and distance helps scientists determine the energy of the radiation passing through the chamber.
