内容記述
The modified integral counting method by control of the high voltage of photomultipliers (MICM-HV) was investigated to show its applicability for radioactivity analysis. In the MICM-HV, pulse height spectra of the sample are measured at various high voltages of photomultipliers in the liquid scintillation counter. The spectra are converted to integral spectra, which are extrapolated to give the convergence point. The counting rate at the convergence point corresponds to the disintegration rate of the sample. The MICM-HV determines the disintegration rate with one cocktail sample and the method requires no unquenched standard sample.
