Elektrische Leitfähigkeitsmessungen und Bestimmung des G(freie Ionen)-Wertes bei röntgenbestrahlten Flüssigkeiten verschiedener Molekularstruktur

Abstract

Electrical conductivity measurements were made for the determination of G (free ions) in some hydrocarbons. The radiation source was a x-ray tube operated at 55 kV. Four quantities were measured for each liquid: 1. the stationary electrical conductivity at low electric field strength during irradiation, 2. the mobilities of the radiation-induced ions, 3. the volume recombination coefficient, and 4. the absorbed dose rate. All measurements were performed with aerated liquids at room temperature. The following G-values were obtained: n-pentane 0,1; n-hexane and n-heptane 0,09; iso-octane 0,11; cyclohexane 0,06; benzene 0,07; decalin 0,04. The standard deviation was estimated to ± 25 per cent.
