Abstract

The method of isotope dilution for determining the exchangeable mass of different substances in living organisms is, at best, approximate. A formally exact method, defining the otherwise vague concept of exchangeable mass, is proposed. The new method may serve as a standard for determining errors in results obtained by the earlier method.
