A brief review is given of the extensive published work which deals with the induced conduction in liquid dielectrics and, in particular, the results concerning the mobility, recombination and diffusion of ions which are produced by ionization in saturated hydrocarbons are discussed in some detail. It is shown that for the mobility of positive and negative ions, as well as for the recombination coefficients, relations are valid which, apart from constant parameters depending on the type of liquid, contain only the viscosity. Using the formula which the author has derived for the viscosity of saturated hydrocarbons it is thus possible to express all the above coefficients for these substances in terms of temperature and molecular structure. The activation energy involved in these processes may also be established. Also reviewed is the recent work on liquefied noble gases which is significant for the study of the mechanism of ion mobility in relation to the molecular structure of these liquids. Lastly the possibility of using liquid-filled ionization chambers for dosimetry is discussed. A formula for the ionization current in such a chamber filled with saturated hydrocarbons is given and the effectiveness of such a device for a wide spectrum of quantum energy is established.
