Abstract

Errors pertinent in dual beam absorptiometry have been studied. Five areas are given in detail: 1. Scattering, in which a computer analysis of multiple scattering shows little error. 2. Geometrical configuration effects, in which the shape of the sample influences accuracy. 3. Poisson variations, in which dosage and statistical error are minimized. 4. Absorption coefficients, in which variations in compilations are examined. 5. Filtering, wherein is shown the need for Kβ filtering. A zero filter system is outlined.
