• The energy required to produce one ion pair, W-value, for electron in vapours of several dielectric liquids has been determined by Bragg-Gray principle. The cylindrical ionization chamber used for measurements was made of stainless steel. Its wall thickness and effective volume were 1 mm and 10 cm^3, respectively. The vapours were obtained from the liquid samples for spectroscopy. The experiments were carried out up to saturated vapour pressure of these liquids at room temperature. ^<60>Co was used for gamma-radiation source in every case. To determine the W-value for several kinds of vapours, argon, nitrogen and air were used as standards. The W-value obtained for vapours of n-hexane, cyclohexane, benzene, carbon disulphide, dichloromethane, and carbon tetrachloride were 27.9, 25.3, 29.0, 24.7, 26.1, and 26.0 eV, respectively.
