THE ABSOLUTE STANDARDIZATION OF RADIOISOTOPES BY THE BETA-GAMMA COINCIDENCE METHOD USING HIGH EFFICIENCY DETECTORS
Technical Report
·
OSTI ID:4292734
The corrections pertaining to absolute disintegration rate determinations by the 4 pi beta - gamma coincidence method are discussed. It is demonstrated that because of the high efficiency of the 4 pi detector most corrections are small. In general, the largest corrections, apart from background are those due to the accidental coincidence rate and dead time losses, expressions for which are derived. A 4 pi beta - gamma coincidence apparatus which was developed in this laboratory is described. An account of the performance of this instrument is given together with the experimental verification of the accidental coincidence rate and dead time corrections. (auth)
