Appropriate quenching level in modified integral counting method by liquid scintillation counting
- 104 Downloads
To know the appropriate quenching level, the modified integral counting method with various quenched samples (MICM-VQ) was applied for the determination of the disintegration rate of 14C or 35S. The appropriate quenching level for the MICM-VQ was considered by the comparison of the integral scintillation spectrum and the integral beta spectrum. The appropriate quenching level of sample in the MICM-VQ was found. The disintegration rate of sample having appropriate quenching level could be determined by the MICM-VQ.
