The detection and the spectrometry of $beta$-radiation in aqueous solutions by the scintillation counting technique is studied with a water fraction (30-100%) high enough to bar the use of the scintillators otherwise customarily employed. The following possibilities are investigated and delineated in terms of their applicabilities: 1) Cerenkov count. 2) Emulsion count (emulsification of a liquid scintillator). 3) Micelle count (solubilization of a liquid scintillator). The third possibility turns out to be highly suitable: even with 75% volume percent of water in the bulk quantity the detection of $beta$-radiation is still possible with a high counting yield (with the exception of low energy radiation, as in the case of $sup 3$H). The performance capability of micelle counting is demonstrated by the example of a measurement for gamma dosimetry in water; this is the first measurement of a gamma dose with a uniformly distributed gamma emitter.
