摘要： A METHOD IS PROVIDED FOR COUNTING ATOMIC DISINTEGRATIONS OF RADIOACTIVE MATERIAL WHICH IS ACCOMPANIED BY EMISSION OF B-RAYS, WHEREIN THE MATERIAL IS DISPERSED IN A SCINTILLATION LIQUID WHICH CONTAINS AN OXDIAZOLE COMPOUND OF THE FORMULA

A1-1,4-PHENYLENE-(1,3,4-OXADIAZOL-2,5-YLENE)M-

1,4-PHENYLENE-B1

WHEREIN A1 IS A BRANCHED CHAIN ALKYL, B1 IS HYDROGEN, PHENYL, LOWER ALKYL, OR LOWER ALKOXY, AND M IS 1 OR 2. THE COUNTS PER MINUTE EMITTED BY THE MATERIAL DISPERSED IN THE SCINTILLATION LIQUID ARE MEASURED WITH A SUITABLE INSTRUMENT SUCH AS LIQUID SCINTILLATION SPECTROMETER.
