Simple Cloud Chambers Using Gel Ice Packs
Kamata, Masahiro; Kubota, Miki
Physics Education, v47 n4 p429-433 Jul 2012
Although cloud chambers are highly regarded as teaching aids for radiation education, school teachers have difficulty in using cloud chambers because they have to prepare dry ice or liquid nitrogen before the experiment. We developed a very simple and inexpensive cloud chamber that uses the contents of gel ice packs which can substitute for dry ice or liquid nitrogen. The gel can be frozen in normal domestic freezers, and can be used repeatedly by re-freezing. The tracks of alpha-ray particles can be observed continuously for about 20 min, and the operation is simple and easy. (Contains 1 table, 8 figures and 1 footnote.)
