Abstract EN
One of the main problems in quantitative gamma-ray spectroscopy is the determination of detection efficiency, for different energies, source-detector geometries, and composition of samples or sources.
There are, in principle, three approaches to this issue: experimental, numerical, and semiempirical.
Semiempirical approach is based on the calculation of the efficiency for the measured sample on the basis of an experimental efficiency measured on the same detector, but with a calibration source that can be of different size, geometry, density, or composition—the so-called efficiency transfer.
The aim of this paper is to analyze the semiempirical approach, using EFFTRAN and MEFFTRAN software as a typical example.
These software were used in the Department of Radiation and Environmental Protection, Vinča Institute of Nuclear Sciences, on three HPGe detectors.
The results were compared to the experimentally obtained efficiency, and further validation is performed by measuring reference materials issued within the framework of several interlaboratory intercomparisons.
The analysis of the results showed that the efficiency transfer produces good results with the discrepancies within the limits of the measurement uncertainty.
Also, for intercomparison measurement, utest criterion for the trueness of the result was applied showing that the majority of the obtained results were acceptable.
Some difficulties were identified, and the ways to overcome them were discussed.
