Аннотация доклада:
The scintillation detector was constructed to research ultralow concentrations of 14C in liquid scintillator samples. The detector is placed in the low background Laboratory BNO INR RAS at a depth of 4900 m.w.e. Measurements of 14C abundance was done for the samples of liquid scintillator on base of linear alkylbenzene. The detector counting rate was measured and the ratio 14C/12C was extracted from the experimental spectrum the LAB sample. The background model was developed and applied for 14C abundance analysis. The value obtained is 14C/12C (9.1 ± 1.0) ×10-16.
