Representative and highly sensitive express method of measurement of f-activity

The method for determination of f-activity (spontaneous fission) of samples based on a combination of multiplicity spectrometry, measurement of radiation energy, and registration of time of long-range fission products is considered. The method is representative, highly sensitive, and fast. The minimum determined value of the specific activity is 1.4⋅10-3 Bq/g.
