Comparison of the Performance of Different Uranium Enrichment Analysis Codes Using a Range of Detector Types

چکیده
This paper describes the results of a set of measurements carried out to assess the state of the practice of relative uranium enrichment measurements by gamma ray spectrometry and to compare a range of approaches by carrying out measurements on a set of uranium samples with known enrichments. Measurements made by a team from Canberra Industries were carried out using two detector/counting chain combinations. The data were collected in such a way as to allow it to be analyzed using different uranium enrichment analysis methods. The results obtained using different detector and enrichment analysis method combinations were compared with each other and with the known values for each sample. Results of these measurements show that in controlled experimental conditions the total uncertainty of reported enrichment is below the procedural upper reporting limit of ±20%. Measurements tend to be better with a BeGe detector over a coaxial detector.

Depleted Uranium in the food chain at south of Iraq
Background: Depleted Uranium (DU) is uranium with low content of U 235 produced as a result of uranium enrichment. DU has high density (19.05 g /cm3), which is 2.54 more than Iron, so it’s high penetrating power makes it preferable as emanations with high penetration power. It was used in second Gulf ware in 1991 for first time. The radioactivity of soil, plants, fruit, meat, milk and water i...
