Abstract:
Self—absorption of (14)C beta radiation is shown to follow an exponential relationship under certain conditions. A new method of BaCO(2) fixation of activity is presented by which it is possible to determine productivity without using the efficiency of the detector in the calculations. Many objections to the Geiger—Muller method are explained, and corrections are suggested for the methods of Steemann Nielsen and of Sorokin.
