Abstract: | A portable liquid scintillation counting system based on the triple-to-double coincidence ratio (TDCR) method was developed at Sofia University “St. Kliment Ohridski”. The system consists of a miniature TDCR counter with cylindrical optical chamber and a specialized TDCR counting module named nanoTDCR. The nanoTDCR module is produced by the labZY company and provides several important new TDCR counting functionalities like: individual extending-type dead-time in each channel; simultaneous counting with two different extendable dead-times and two different coincidence windows and simultaneous TDCR counting and spectrum acquisition. The performance of the new system was tested in benchmark comparisons with the LNHB’s primary TDCR counting system of activity measurements of 241Am, 3H, 14C and 63Ni. Good agreement between the two systems was observed. |
