Particles in the Mist
In this project, there was a cloud chamber built to see radioactive decay particles with a radioactive source. In this project an ionizing smoke detector is being used as the radioactive source. The difference between an ionizing smoke detector and one that is not is that they tend to respond 30-90secs faster to fast flame fires than photoelectric fire alarms. . A cloud chamber is a sealed environment containing supersaturated vapor of water or alcohol. Supersaturated water vapor is a vapor ready to condensate, but lacking nuclei on which to condense. In this project 91% isopropyl alcohol is being used. When decay particles travel through the chamber,
