Performance of portable TDCR systems developed at LNE-LNHB
2022年7月1日 · In this paper, we will present the newly developed portable TDCR liquid scintillation measurement systems. Two kinds of devices have been developed and designed at LNE-LNHB and built using fused deposition modelling (FDM) 3D printing: a mini-TDCR (25 cm diameter, 10 cm height) and a micro-TDCR (16 cm diameter, 10 cm height).
A review of the triple-to-double coincidence ratio (TDCR) method …
2003年5月1日 · The triple-to-double coincidence ratio (TDCR) method is a fundamental method in liquid scintillation counting (LSC) developed for determination of the massic activity of pure β - and pure electron capture (EC) emitters in solution.
Triple Coincidence Applications | Hidex
The TDCR method has been originally developed for the direct determination of the absolute activities of β- and EC-decaying radionuclides in liquid scintillator medium. TDCR combines experimental data with theoretical calculations of the detector efficiency.

A review of the triple-to-double coincidence ratio (TDCR
This paper gives a review of the development of the triple-to-double coincidence ratio (TDCR) method for standardizing pure beta- and pure electron capture (EC)-radionuclides. The initial idea of Schwerdtel and practical realization and elaboration of the TDCR method by Pochwalski is …
Performance Evaluation of FPGA-based Standalone, Portable TDCR …
2024年5月3日 · The liquid scintillation counting based triple to double coincidence ratio (TDCR) method is a widely employed, direct activity determination technique to standardize pure beta emitters. An “FPGA-based standalone, portable TDCR system” is developed for absolute activity measurement of pure beta-emitting radionuclides.
Basic Metrology: Advancing Triple-to-Double Coincidence Ratio …
2021年3月22日 · The triple-to-double coincidence ratio (TDCR) method of liquid scintillation (LS) counting employs three detectors to determine experimental counting efficiencies so that activity can be measured independent of calibration standards.
