In general, a liβuid scintillation method can be applied to determine the tritium concentration in an environmental water such as rain water and river one. In this case, the followings are generally carried out: (1) a sample solution is directly measured in a large vial for long time (about several days) by using a low-back liβuid scintillation counter; (2) after the sample solution is enriched by applying the electrolysis method, the solution thus enriched is measured with a normal liβuid scintillation counter. However, the tritium separation factor (βa) in the solution obtained by the electrolysis-apparatus having a film of solid polymer electrolyte by applying the electrolysis method (SPE electrolysis method) is not so large (about 6) . Increasing βa in the solution is an important matter since it leads to an increase in the accuracy of tritium concentration in an environmental water. We then considered the effect of a high magnetic field on the electrolysis, the electrolysis-apparatus based on the SPE electrolysis method was set in the field, and the electrolysis was carried out under each high magnetic field in the range of 0-3 T. The electrolysis-apparatus was set as follows: the direction of the electrolysis current was at (a) right angle, (b) counter current, (c) reverse current, to the magnetic field. Conseβuently, the following three were obtained : in the case of (a), βa increased with increasing the magnetic field between 0 and 2 T (0-2 T), but decreased with increasing one (2-3 T) ; in that of (b), a increased with increasing the magnetic field (0-3 T), and especially, exponentially increased (2-3 T) ; in (c), βa slightly increased (0-3 T) . From the above-mentioned, the following two matters were clarified: (1) the effect of the magnetic field on the electrolysis is fairly large under a certain condition ; (2) a large βa can be obtained when an appropriate condition is chosen.
