Balanced Ionization Chamber for Differential Measurements of Gamma Rays
"The purpose of the work was to develop a method of measuring very small differences in the half lives of gamma ray emitting radioactive substances. The apparatus was then used to try to detect a difference in the half lives of Be7 metal and BeO. The results of the measurements on the two different chemical forms of beryllium will be given" (p. 1).
