Conclusions The advantages of the above method of absolute measurements of β-active liquids consist of: 1. The absence of any intermediate chemical operations in preparing samples; 2. The absence of such procedures as drying the source, with the related errors which are difficult to estimate, and are due to possible losses owing to the chemical instability of the precipitated preparation or of the isotope exchange; 3. The absence of any corrections for self-absorption, back-scattering, etc. The efficiency of the compensated element counting is virtually equal to 100%; 4. High accuracy; 5. Speed of operation. The duration of one measurement, including the preparation of the sample, amounts to no more than 1 hr as compared with 10–15 hr required for other methods.
