4$pi$$-$$beta$$-$$gamma$ COINCIDENCE COUNTING FOR THE CALIBRATION OF NUCLIDES WITH COMPLEX DECAY SCHEMES
Journal Article
·
· Intern. J. Appl. Radiation and Isotopes
The 4 pi - beta - gamma coincidence calibration is normally used only for nuclides with decay schemes which are both reasonably well known and fairly simple. It is shown that by a systematic variation of the mean beta -efficiency alpha m (the ratio of the coincidence to the gamma -counts) the error caused by the selfabsorption of the beta -rays can (in 4 beta - pi counting) be eliminated by an extrapolation method. This is possible even for very complex and uncertain decay schemes, provided that a least one beta - gamma cascade is known. The results of a calibration of a solution of Ce/sup 144/ + Pr/sup 144/ are reported as an example. (auth)
