Becker Emanometer
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
The Becker emanometer is an instrument proposed in 1910 for measuring radium emanation with high precision and speed. The device collects the emanation in a special reservoir, transfers it to the measuring unit, and determines its magnitude based on the rate of discharge of an electrometer.

BECKER EMANOMETER (Becker), an instrument used for measuring radium emanation, proposed by Becker in 1910 at the radiology congress in Brussels. Compared to other measuring instruments (fontaktoscope, fontactometer), apart from its accuracy, the Becker emanometer has the advantage of allowing measurements to be performed extremely rapidly. The emanation under investigation is first collected in a special reservoir, from which it passes directly into the measuring part of the instrument; the magnitude of the emanation is judged by the rate of discharge of the electrometer.
