Abstract

W-values are of considerable interest in the determination of absorbed dose by gas filled detectors, particularly in the fields of radiobiology and radiation protection. This paper describes experimental work undertaken in the measurement of W-values for Rossi-Failla type tissue-equivalent gas and its constituents using alpha particles in the range 1.1-3.9 MeV. Descriptions are given of the ionisation chamber used and the procedure adopted. Results and uncertainties are shown together with results of other workers for comparison. It is concluded that in general there is good agreement among the values quoted by different authors and that the experimental data available provides a reasonable basis for dose assessment.
