MCNP modelling of scintillation-detector gamma-ray spectra from natural radionuclides
Autor: Hendriks, Peter, Maucec, M, de Meijer, RJ
Publikováno v: Applied Radiation and Isotopes, 57(3):PII S0969-8043(02)00118-5, 449-457. PERGAMON-ELSEVIER SCIENCE LTD
gamma-ray spectra of natural radionuclides are simulated for a BGO detector in a borehole geometry using the Monte Carlo code MCNP. All gamma-ray emissions of the decay of K-40 and the series of Th-232 and U-238 are used to describe the source. A pro

Radiometric sand-mud characterisation in the Rhine-Meuse estuary part A. Fingerprinting
Autor: van Wijngaarden, M, Venema, LB, De Meijer, RJ, Zwolsman, JJG, Gieske, JMJ
Publikováno v: Geomorphology, 43(1-2), 87-101. ELSEVIER SCIENCE BV
The composition of the underwater sediment bed is often defined in terms of the mud (63 and 63 mum) and sand (>63 mum) as: 46.2 +/- 1.9 Bq/kg U-238 and 9.3 +/- 0.9 Bq/kg U-238 and 45.6 +/- 1.9 Bq/kg Th-232 and 9.7 +/- 0.9 Bq/kg Th-231, respectively.

Radiometric sand mud characterisation in the Rhine-Meuse estuary part B. In situ mapping
Autor: van Wijngaarden, M, Venema, LB, De Meijer, RJ
Publikováno v: Geomorphology, 43(1-2), 103-116. ELSEVIER SCIENCE BV
Traditionally, obtaining accurate spatial information about the textural composition of heterogeneous aquatic sediments requires extensive sediment sampling. To avoid a costly and time-consuming operation, a new in situ technique has been investigate

Full-spectrum analysis of natural gamma-ray spectra
Autor: Hendriks, Peter, Limburg, J, de Meijer, RJ
Publikováno v: Journal of Environmental Radioactivity, 53(3), 365-380. ELSEVIER SCI LTD
In this paper, a new system to measure natural gamma -radiation in situ will be presented. This system combines a high-efficiency EGO scintillation detector with full-spectrum data analysis (FSA). This technique uses the (nearly) full spectral shape
