Cloud Chamber

A cloud chamber is prepared and the mechanism for showing a radioactive particle trail is briefly described. A radioactive source of Pb-210 which is primarily a low energy beta emitter is placed at the lower center of the chamber. One of the daughter nuclei of Pb-210 is Po-210 which emits high energy alpha particles that fly through the cloud chamber. The path of these alpha particles is observed and the random nature of the radioactive decay is demonstrated.
